Answer:
Nervous and endocrine systems
Explanation:
The sensory receptors of the nervous system sense the stimuli (change or deviation from a homoeostatic condition) and send the information to the central nervous system. The various components of the brain (CNS includes the brain and spinal cord) integrate the sensory information and command the effect organs, the muscles, and exocrine and endocrine glands to perform the desired action to restore the homeostasis. The endocrine glands secrete hormones to regulate the various bodily function. In this way, Nervous and endocrine systems together maintain the homeostasis.
For example, an increased blood sugar level is sensed by sensory receptors of the nervous system. Pancreas (a component of endocrine and digestive systems) is stimulated to release the hormone insulin to restore the normal blood sugar levels.
Answer:
The correct answer is- nervous and endocrine systems
Explanation:
Homeostasis is the ability of a system to resist the change and maintains a stable and constant condition. In our body homeostasis occurs due to the coordination of all body systems. Like the kidney which comes in the excretory system helps in maintaining the osmotic balance in blood.
This coordination is achieved mainly by the nervous and endocrine system. Nervous systems coordinate different systems in the body by accepting the signals and releasing the informatory signals to them.
Endocrine system release hormones in the blood that reaches to target organs and regulate their function that helps in maintaining homeostasis in the body.

After packing acrylic resin into the denture flasks, one should wait to cure the resin to ___.
Answer:make sure the temperature equilibrium exists between flask and acrylic
Explanation: It is fundamental after packing acrylic resin into the denture flasks, one should wait to cure the resin to "make sure the temperature equilibrium exists between the flask and acrylic".
To ensure the optimal curing of acrylic resin in the denture flasks, it is necessary to follow appropriate procedures that are similar to the curing or solidifying processes in other laboratory settings. After packing the acrylic resin into the denture flasks, the resin typically requires a certain period of time to cure. This process is akin to allowing gels to solidify in biological experiments or epoxy diane resins to cure in polymer chemistry contexts.
In these scenarios, specific times are often recommended to achieve complete solidification or curing. For instance, gels may take about 20 to 30 minutes to solidify after setting, and an epoxy resin could require measurements at intervals from 5 to 20 minutes during its curing process.

Bacteria that contain recombinant plasmids can be easily isolated because: Select one:
a. they are designed to be resistant to certain antibiotics
b. their colonies will be distinguished by a color variation from those colonies containing non recombinant plasmids
c. they are smaller than non-recombinant bacteria
d. they are larger than non-recombinant bacteria
Answer:
The correct answer is a. they are designed to be resistant to certain antibiotics
Explanation:
Recombinant plasmids are those bacteria in which a foreign genetic material is placed for giving some addition characteristic to the plasmid. The recombinant plasmid must have origin or replication and a selectable marker. It should produce its numerous copy in its host.
So most of the plasmids have antibiotic-resistant gene as selectable marker. So the bacteria transformed with the recombinant plasmid can be isolated from other bacteria by growing them on medium containing the antibiotic that the recombinant plasmid in bacteria has.
For example, bacteria having a recombinant plasmid that contains an ampicillin-resistant gene can grow in medium having ampicillin antibiotic but other bacteria that do not have this gene can not grow.
The Position Statement 15.27 The Licensed Vocational Nurse Scope of Practice on the board's website outlines that LVNs have a "directed" scope of practice "under supervision." This means that:
Answer:
LVN can perform the initial assessment based on the defined presumptive and conclusive sign and submit his/her findings to the physician
Explanation:
Under this, LVN performs assessment on his/her own to determine the changes in the condition of patient and report it to the physician. Their task involves identifying some presumptive signs such as response state of patient, his/her pulse, body temperature, pupil etc. and conclusive signs such as presence of liver mortis, and any sign of irreversible death.
The LVN must submit his/her clinical finding report to the physician
Position Statement 15.27 outlines that Licensed Vocational Nurses (LVNs) have a 'directed' scope of practice under supervision. This means that LVNs can perform certain medical duties under supervision of registered nurses or physicians. However, more complex tasks requiring vast judgment and specialization are beyond their 'directed' scope of practice.
Explanation:Position Statement 15.27 The Licensed Vocational Nurse Scope of Practice denotes that LVNs, or Licensed Vocational Nurses, have a 'directed' scope of practice under supervision. This means that LVNs are allowed to perform certain medical duties under the direct oversight of registered nurses, physicians or other healthcare professionals. The term 'directed' signifies that although they are licensed nurses, their actions in the medical field are subject to the supervision and guidance of professionals who hold a more comprehensive license.
LVNs responsibilities may include tasks such as monitoring patient vitals, administering medications, and helping patients with personal hygiene. However, complex tasks that entail more intensive judgement and specialization, like treatment plan creation or serious surgical procedures, are beyond the 'directed' scope of practice of an LVN.

The endocrine system incorporates feedback mechanisms that maintain homeostasis. Which of the following demonstrates negative feedback by the endocrine system?a. During labor, the fetus exerts pressure on the uterine wall, including the production of oxytocin, which stimulates uterine contraction. The contractions cause the fetus to push on the uterine wall , increasing production of oxytocin.b. After a meal, blood glucose levels become elevated, stimulating beta cells of the pancreas to release insulin into the blood. Excess glucose is then converted into glycogen in the liver, reducing blood glucose levels.c. At high elevations, atmospheric oxygen is more scarce. In response to signals that oxygen is low, the brain decreases an individual’s rate of respiration.d. A transcription factor binds to the regulatory region of a gene, blocking the binding of another transcription factor required for expression.
Answer:
Answer is option B.
After a meal, blood glucose levels become elevated, stimulating beta cells of the pancreas to release insulin into the blood. Excess glucose is then converted into glycogen in the liver, reducing blood glucose levels.
Explanation:
Homeostasis is the inclination of the various systems in the human body to stay in a normal, stable range for health by self-regulation through negative and positive feedback controls. It maintains equilibrium and provides stability to the human body.
A negative feedback loop (inhibitory loop) is a type of self-regulating system in which increased output from the system inhibits future production by the system. Examples of negative feedback to achieve homeostasis are blood pressure, body temperature, blood sugar, etc. During blood sugar homeostasis, when blood glucose levels rise, pancreatic beta cells release insulin. Insulin also converts glucose into glycogen (glycogenesis) for storage in the liver. When blood glucose levels decrease, pancreatic alpha cells release the hormone glucagon. In the liver, glucagon breaks down the stored glycogen into glucose (glycogenolysis). The glucose then enters the bloodstream and restores the blood glucose levels to normal.
In a positive feedback system, the original stimulus is amplified by the output. Examples of a positive feedback system are childbirth, lactation, blood clotting, etc. During childbirth, the hormone oxytocin released increases and speeds up the contractions.

b. the activation of bodily systems during prolonged stress.
c. body movement, balance, coordination, and fine motor skills.
d. outward family resemblances, such as the shape of the nose and the face.
Answer:
Answer is C. Body movement, balance, coordination and fine motor skills.
Explanation:
The cerebellum known to be responsible for receiving signals from other parts of the senses, the brain and the spinal cord.
Cerebellum is found in the hindbrain of vertebrates, and it is underlying the occipital and temporal lobes of the cerebral cortex.
Note that the hindbrain is divided into two, these are superior metencephalon and the inferior myelencephalon. The cerebellum is from the superior metencephalon division.
The correct option is c. The cerebellum is responsible for body movement, balance, coordination, and fine motor skills, as well as playing a role in emotional responses and learning.
The cerebellum is responsible for body movement, balance, coordination, and fine motor skills. This part of the brain, often referred to as the "little brain," consists of two wrinkled ovals located behind the brain stem and plays a critical role in coordinating voluntary movement. Damage to the cerebellum can cause difficulty in walking, keeping balance, and holding hands steady. Additionally, the cerebellum is influenced by alcohol consumption, leading to impaired walking in a straight line. Beyond physical coordination, it also contributes to emotional responses, helps in discriminating between different sounds and textures, and is essential in learning processes.
Which term is used to describe the amino acids which cannot be synthesized by the cell but must be acquired from an outside source?
Answer:
Essential amino acids
Explanation:
The amino acids that cannot be synthesized by a cell and must be provided by any other source are called essential amino acids. For instance, proteins are made up of 20 standard amino acids. The cells in humans are incapable of synthesizing many amino acids which in turn are called essential amino acids. Histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine are the essential amino acids that must be taken in diet.
Answer:
Essential amino acids
Explanation:
Some amino acids cannot be produced in our body instead they are extracted from the external food sources which are known as essential amino acids Food consumed ,provides essential amino acids. During digestion food is broken down into simple substance and protein within it is digested. Once the protein is digested, essential amino acids are extracted. In totality, there are 9 essential amino acids.

Circulatory systems in molluscs: a) are closed in all species of molluscs. b) are open in species of large-sized molluscs and are closed in species of small-sized molluscs. c) are open in species of small-sized molluscs and are closed in species of large-sized molluscs. d) are open in all species of molluscs. e) are open or closed without regard to body size.
Answer:
b) are open in species of large-sized molluscs and are closed in species of small-sized molluscs.
Explanation:
Class Cephalopoda are the largest molluscs and are known for open circulatory system(enclosed blood vessels do not totally contain blood as blood is pumped with the aid of blood vessels from the gills into body cavities also known as hemocoels by the heart)
Final answer:
Molluscs exhibit varied circulatory systems, with most possessing an open circulatory system, while more active species like squids have a closed circulatory system to support their higher metabolic demands.
Explanation:
The circulatory systems in molluscs can vary, being either open or closed depending on the species. Most mollusks, especially those that are not particularly large or active, have an open circulatory system, where the blood (or hemolymph) is pumped into a hemocoel and is not entirely contained within blood vessels. This type of system is less energy-intensive but does not support high levels of oxygen delivery to tissues, which is fine for less active mollusks. However, more active mollusks, like squids, have evolved a closed circulatory system because they require more efficient oxygen and nutrient delivery to support their fast movements and higher metabolic rates. Such a system, where the blood is contained entirely within vessels and circulated by the heart, is more energy-demanding but supports greater activity levels. Therefore, the claim that circulatory systems in molluscs are open in all species or closed without regard to body size is incorrect. Instead, more active, typically larger molluscs may have a closed system, while the less active, often smaller molluscs usually have an open system.

What is the primary fuel for anaerobic atp production for activities lasting 45-120 seconds?
Answer:
The correct answer is- muscle glycogen
Explanation:
During the first few seconds of exercise, the stored ATP in the resting muscles are used to provide energy to the body once the ATP is depleted in few seconds then creatine phosphate is used to provide energy.
ATP and creatine phosphate only provide energy for up to 15 seconds after that the muscle starts anaerobic respiration for providing instant energy because in starting, the rate of respiration is not that much high that instant supply of adequate oxygen can be provided to form ATP.
Therefore muscle switches to anaerobic respiration to form ATP by using glucose of glycogen that is stored in the muscles. It last about 45-120 seconds and after that muscles use aerobic respiration to make ATP.
A biologist spends her summer break collecting frogs from a remote jungle in Peru. She discovers two distinct color forms that could be variants of a single species or two different species. What would be the most direct test of their species status under the biological species concept?

When making transgenic mice, to determine whether there has been stable integration of a transgene into the mouse chromosome, tail biopsies are taken from the mouse pups and tested for the presence of the transgene by
Answer: Western blot
Explanation: western blot is a laboratory method used to detect specific protein molecules from among a mixture of proteins.
The presence of a transgene in transgenic mice is confirmed using reporter genes such as the green fluorescent protein (GFP). When the mouse pups, which should express the reporter gene if the transgene has been successfully integrated, are exposed to UV light, those that fluoresce under the light have the GFP and hence the transgene is successfully integrated.
Explanation:When making transgenic mice, tail biopsies are taken from the mouse pups to check the stable integration of a transgene into the mouse chromosome. This is done by testing for the presence of the transgene. Most often, the transgene that has been stably integrated is linked to a reporter gene.
Reporter genes are genes that are not present in the organism and that express easily-observable characteristics. When the transgene has been successfully integrated, the reporter gene will also be present, and its expression can be easily monitored. This is often done by linking the transgene with genes encoding for fluorescent proteins, such as the jellyfish protein green fluorescent protein (GFP).
When the mouse pups are then exposed to UV light, those that fluoresce under the light have had the GFP reporter gene integrated successfully and therefore, by extension, the transgene.
Another method would be to use a single-stranded DNA probe labeled with a molecular beacon, typically fluorescence or radioactivity, that can bind with the transgene if it is present in the sample taken from the mouse pups.

A 9-month-old child with cystic fibrosis does not like taking pancreatic enzyme supplement with meals and snacks. The mother does not like to force the child to take the supplement. The most important reason for the child to take the pancreatic enzyme supplement with meals and snacks is:
1.The child will become dehydrated if the supplement is not taken with meals and snacks.
2.The child needs these pancreatic enzymes to help the digestive system absorb fats, carbohydrates, and proteins.
3.The child needs the pancreatic enzymes to aid in liquefying mucus to keep the lungs clear.
4.The child will experience severe diarrhea if the supplement is not taken as prescribed.
Answer:
The correct answer is 2. "the child needs these pancreatic enzymes to help the digestive system absorb fats, carbohydrates, and proteins".
Explanation:
90% of patients with cystic fibrosis get the pancreatic enzymes supplement because of their pancreatic insufficiency. These enzymes are released in the intestine and help to digest food.
The enzymes´ principal functions are:
- To digest carbohydrates, proteins, and fats;
- To help to gain weight;
- To promote the absorption of nutrients.
To get an appropriate corporal weight and an improved lungs´ functioning it is important to take the enzyme supplement with every meal. It reduces bad absorption and improves nutrition.

It also travels through chylomicrons in blood stream. some of the fat is used by the body cells and tissues and some goes to the liver. Than it transformed into many other cholesterol and triglyceride form.
Molecules A and B come in contact with the cell membrane of the same cell. Molecule A passes through the membrane readily, but molecule B does not. Which statement could describe molecules A and B?
Answer:
Molecule A is a simple sugar or amino acid, while molecule B is a starch or protein.
Explanation:
Molecule A, as a simple sugar or amino acid, consists of small molecules which can readily pass through the cell membrane, while Molecule B, as a starch or protein, consists of large molecules, thus, can't pass across the cell membrane.
This is the reason why the cell membrane is considered to be selectively permeable.
Molecule A, which readily passes through the cell membrane, is likely a small, nonpolar molecule. Molecule B does not pass freely, suggesting it could be a larger, polar molecule, which are typically unable to cross the membrane without assistance, possibly through facilitated diffusion.
Explanation:The molecules A and B described in your question seem to exhibit different behaviors in contact with the cell membrane because of their different properties. Molecule A is likely a small and nonpolar molecule, which is consistent with the properties needed to pass freely through the cell membrane's lipid bilayer. On the other hand, molecule B could be a polar molecule or a larger substance. These types of molecules do not readily pass through the cell membrane due to the hydrophobic (water-repelling) nature of the lipid bilayer's interior. Instead, these substances require special means of transport, such as facilitated diffusion, which involves protein channels in the membrane, to pass through.

Infection caused by __________ is of greatest concern to pregnant women and those with compromised immune systems.
Answer:
Listeria
Explanation:
Listeria causes invasive syndromes such as meningitis, sepsis, and stillbirth in pregnant or immunosuppressed people. It is an intracellular pathogen and affects the persons with deficient cell-mediated immunity. Bacteria from this genus are part of the normal gastrointestinal microbiota in healthy individuals. However, in immunosuppressed individuals, the bacterium uses proteins such as internalin and phospholipase C for invasion, intracellular multiplication, and cell-to-cell spread.
Pregnant women are at the increased risk of infection due to both systemic and local immunological changes that mostly occur during pregnancy. For example, local immunosuppression at the maternal-fetal interface of the placenta may support the intrauterine infection.
An autoimmune disease is:_________
A. Excessive formation of antibodies following exposure to foreign material.
B. an extreme response to normally harmless material in the environment.
C. An abnormal response to ingested food and drugs.
D. Failure of the immune system to distinguish self from nonself.
Final answer:
An autoimmune disease is a condition where the immune system fails to recognize the body's own cells as self, leading to it attacking its own tissues. The correct answer is D.
Explanation:
An autoimmune disease occurs when the immune system cannot distinguish between self and non-self cells and molecules. This leads to the immune system mistakenly attacking the body's own healthy cells, believing they are foreign invaders. Among the given options, the correct answer is D: Failure of the immune system to distinguish self from nonself.
Autoimmunity involves a loss of immune tolerance, which is the immune system's ability to ignore the body's own cells and only target pathogens. When B cells and other components of the adaptive immune response fail to recognize the body's own molecules, they can lead to tissue damage, altered organ function, and various hypersensitivity reactions associated with autoimmune diseases. Symptoms can often be mixed and may come and go, which can make accurate diagnosis challenging.

Answer:
Pseudo-Science (Astrology, Iridology, reflexology...) Ect.
Explanation:
The Scientific method has to be proven and tested on.
Final answer:
Areas such as morality, aesthetics, spirituality, and religion, along with questions of personal beliefs and values, cannot be approached using the scientific method. This is because these areas involve non-material phenomena and subjective evaluations that are not empirically measurable.
Explanation:
Several areas of study cannot be approached using the scientific method due to their nature. These areas include morality, aesthetics, spirituality, religion (theology), arts, music, literature, humanities, and law. They cannot be investigated using scientific principles because they involve subjective, non-material phenomena that cannot be empirically observed or measured. Questions that involve personal beliefs, values, and ethical considerations fall outside the purview of science.
This distinction is significant in debates where objective facts are distinguished from personal values, such as the belief in life after death or the preference for certain types of music. Examples of questions science cannot answer include inquiries into the existence of supernatural beings or forces, discussions on which genre of music is better, or the ethical implications of human cloning.
What two organ systems are most involved in controlling the negative feedback systems of the body?
Answer:
The respiratory system as well as circulatory system (hormonal system) are involved in controlling the negative feedback of our body.
Explanation:
The respiratory system helps in controlling the negative feedback in such a way that if CO2 level increases in body the system acts in such a way so as to decrease its level in body . the system attains a normal level by increasing the blood circulation and increasing the breathing level forcing CO2 outside of our body.
in case of circulatory system, the blood has several hormones released from glands . the most common example is Insulin and Glucagon .
if a person is hypoglycemic then glucagon concentration increases and blood glucose concentration returns to normal and if a person has hyperglycemia then insulin level increases which in turn increases glucose uptake from body and body returns to normal level.

Two students in science class were investigating the effects of osmosis on chickens eggs exposed to varying concentrations of sugar solutions. The total volume of each sugar solution was 300 milliliters. How much solute and solvent is needed to create a 60% sugar solution?
Answer:
The ratio is 180/120
Explanation:
Osmosis is a process which takes place when there are two environments with different concentration in terms of a specific solute and these environments are usually seperated by some sort of membrane which the solute can pass through from one environment to the other. In this case, the egg shell acts as a membrane and since the environment inside the egg is less concentrated than the outside in terms of sugar, the osmosis takes place. To achieve a sugar solution with 60% concentration in this example, the solute and solvent ratio should be as 180 grams of solute which is sugar and 120 mililiters of solvent.
