Answer:
The correct option is this: AN INCREASE IN FLUID TAKEN BY MOUTH WOULD REDUCE THE AMOUNT PRODUCED BY METABOLISM.
Explanation:
Generally, the amount of water consumed by a person normally leads to increase in the amount of urine that the person will excrete, that is, the higher the quantity of water consumed, the higher the quantity of the urine that will be excreted under normal circumstances. Thus, the statement given in option B is false. The statements given in Option C and D are right; during exercise the quantity of sweat produce and lost by the body is higher than the one that is produced when one is not exercising. Also, diarrhea usually lead to loss of water from the body.
Histamine increases blood flow and vascular permeability. This would account for all of the following changes that occur during inflammation, exceptswelling of the inflamed tissue.redness of the inflamed tissue.movement of defense proteins and cells into the interstitial space.chemotaxis of phagocytes.heat of the inflamed tissue.
Answer:
chemotaxis of phagocytes
Explanation:
Histamine is a chemical involved in inflammation but it also has role as a neurotransmmiter in central nervous system and uterus It is synthesized by the two types of cells: basophils and mast cells and it acts via binding to its receptors (histamine receptors). Roles of histamine are:
vasodilatation and consequently decrease in the blood pressureincrease vascular permability in the nose cavity (runny nose)regulates sleep-wake cyclestimulates gastric acid secretion in the stomach etc.The cell membranes of Antarctic ice fish might have which of the following adaptations?A) very long chain fatty acidsB) branched isoprenoid lipidsC) a high percentage of polyunsaturated fatty acidsD) a higher percentage of trans-fatty acidsE) no cholesterol
Answer: a high percentage of polyunsaturated fatty acids
Explanation:
Cell membranes are semi-permeable membrane, which is selective for certain molecules.
The correct answer is:
Option C. a high percentage of polyunsaturated fatty acids
The adaptation of cell membranes of antarctic ice fish are:
1. The ice fish of Antarctica is known as Channichthyidae. The blood of the icefish is extremely low viscous and making it easier to pump throughout the body.
2. The cell membranes of the antarctic fish are made up of unsaturated fatty acids chains. These adaptations of the cell membrane help the fish to survive at a lower temperature. It also helps in maintaining the transition phase of the liquid to the gel phase.
Thus, the correct option is Option C.

The graph below shows the frequency of moths in a population. The original population had more black and white speckled moths, but the new population has more dark-colored moths.
a. What type of selective pressure was taking place in this population?
b. Come up with a hypothesis related to genetic drift or sexual selection about why this shift may have occurred in the population.
Answer:
This actually happened in real life. A hypothesis for b. is that if pollution made the trees in the moths environment darker, then the dark moth population would increase because they blend in with the darker trees better than the speckled moths and are not as visible to predators (this is related to genetic drift). Therefore a. would be natural selection since the dark moths are more fit to the environment.
Final answer:
The type of selective pressure taking place in this population is directional selection. A hypothesis related to genetic drift or sexual selection for why this shift may have occurred in the population is that there could have been a genetic mutation that caused the moths to have a darker coloration.
Explanation:
The type of selective pressure taking place in this population is directional selection. Directional selection occurs when the environment changes, and a population undergoes selection for phenotypes at one end of the spectrum of existing variation.
A hypothesis related to genetic drift or sexual selection for why this shift may have occurred in the population is that there could have been a genetic mutation that caused the moths to have a darker coloration. This mutation would have been advantageous in the new environment, leading to an increase in the frequency of dark-colored moths over time.

Systolic blood pressure is the amount of pressure that blood exerts __________
Answer:
while the heart beats
Explanation:
Blood pressure of the heart is the pressure by which heart pumps blood through the arteries. Since the blood flow through the heart and arteries is pulsatile, there are two heart blood pressures: systolic and diastolic blood pressure. Normal systolic pressure is about 120 mmHg.
Diastolic blood pressure is the pressure of the blood between heartbeats (when heart is not active, relaxed). Normal diastolic blood pressure is about 80 mmHg.

The genetic makeup that is responsible for a particular trait
Answer:
the genotype is responsible for a particular trait or all of the traits
Explanation:
A genotype, containing alleles inherited from the parents, is responsible for a specific trait. The observable expression of this genotype is known as a phenotype, which is influenced by both genetic and environmental factors. Genetic information, coded within the cells' chromosomes, is passed from the parents to the offspring during reproduction.
Explanation:The genetic makeup responsible for a specific trait is referred to as a genotype. The genotype comprises the inherited alleles from an individual's parents, which are the variations of a gene that code for a specific trait. This genetic information is contained within the cells' chromosomes.
The phenotype, on the other hand, is the observable expression of that genotype, a combination of genetic and environmental influences. For example, let's take hair color. A gene may code for hair color, and different alleles of that gene will result in different hair colors. This interaction between the genotype and environmental factors leads to the physical expression of traits.
When a sperm and egg combine during reproduction, each contributes 23 chromosomes, creating a zygote with a total of 46 chromosomes. These chromosomes carry the genetic information that determines the offspring's traits, passing along genes to ensure the offspring will belong to the same species and will have similar characteristics.

Which of the following organisms would occupy the lowest trophic level of any ecosystem?
1. humans, bears, and pigs
2. lions, wolves, and snakes
3. cows, horses, and caterpillars
4. plants, bacteria, and algae
Answer:
4
Explanation:
Because most of these organisms are autotrophs meaning they make their own food from abiotic factors. Organisms higher up the food chain are heterotrophs meaning they feed on other organisms for energy. Organisms at lower trophic levels usually have higher biomass (in higher population numbers) than higher organisms. This is because of the inefficiencies of passing energy up the food chain.
Final answer:
The lowest trophic level in any ecosystem is occupied by primary producers; thus, plants, bacteria, and algae are the correct answer as they can photosynthesize and make their own food.
Explanation:
The organisms that occupy the lowest trophic level of any ecosystem are those that are the primary producers. In the options provided, the organisms belonging to the lowest trophic level would be plants, bacteria, and algae, as they are capable of photosynthesis, making their own food from sunlight, water, and carbon dioxide. These primary producers are at the base of the food chain and provide energy for all other organisms in the ecosystem.
The other options listed, such as humans, bears, pigs (omnivores), lions, wolves, snakes (carnivores), and cows, horses, caterpillars (herbivores) all consume other organisms and so occupy higher trophic levels.

Glucose enters the epithelial cells of the small intestine against its concentration gradient. Select the BEST explanation from the following. Glucose is co-transported in the Na /K pump. Glucose is co-transported with Na , which moves down its concentration gradient into the cell. Glucose follows the water that is pumped into the cell. Glucose is transported through a glucose pump in the apical membrane that hydrolyzes ATP to ADP and Pi. Glucose enters by diffusion.
Answer:
Glucose is co-transported with Na , which moves down its concentration gradient into the cell.
Explanation:
Na/K pump is a pump located on the plasma membrane which uses ATP to move 3 Na ions out the cell and brings in 2 K ions into the cell. It is an example of primary active transport. As a consequence,concentration of Na is higher outside the cell, while K concentration is higher inside the cell.
Glucose is transported in the cell against its gradient, together with Na ions (symport) which move down their concentration gradient.
This is an example of secondary active transport because it uses the energy from the primary active transport to move other substances such as glucose against their own gradients.
Final answer:
Glucose is actively transported into intestinal epithelial cells via secondary active transport using a Na+/glucose symport mechanism. Sodium ions moving down their gradient provide the energy for glucose to be transported against its gradient with the help of SGLT1 and Na+/K+ ATPase.
Explanation:
Glucose enters the epithelial cells of the small intestine against its concentration gradient by a process known as secondary active transport. This involves a symport mechanism, where glucose is co-transported with sodium ions (Na+). The sodium ions move down their concentration gradient into the cell, providing the energy needed to transport glucose against its gradient.
The primary transporter involved is the sodium-glucose co-transporter 1 (SGLT1), which couples the transport of glucose with two sodium ions. This process utilizes the sodium electrochemical potential gradient created by the Na+/K+-ATPase, which actively pumps sodium out of the enterocyte into the blood, maintaining a low intracellular sodium concentration, and allowing the continued inward movement of sodium (and glucose).
Finally, glucose is transported from within the enterocytes into the bloodstream through the basolateral membrane by facilitated diffusion, using the glucose transporter GLUT2.
Which of the following individuals will inherit an X-linked allele from a man who carries it?
A) all of his children
B) all of his daughters
C) all of his sons
D) half of his daughters
Answer:
B) all of his daughters
Explanation:
The males's genome contain XY chromosomes, while female's genome have XX chromosome. If a man has X-linked allele it will be expressed (e.g. the diseases will appear). If a woman has one X-linked allele she will be the carrier (but will not develop the disease). Daughter will inherit one X chromosome from mother and another from father. So, if a man has X-linked disease, all of his daughters will become carriers of the disease.
All of a man's daughters will inherit an X-linked allele from him because males pass on their X chromosomes to their daughters and Y chromosomes to their sons. Daughters will be carriers of a recessive X-linked trait or express a dominant one, while sons have no chance of inheriting an X-linked allele from their father.
Explanation:The individual who will inherit an X-linked allele from a man who carries it will always be all of his daughters. This is because males have one X and one Y chromosome, whereas females have two X chromosomes. A man will pass his Y chromosome to his sons and his X chromosome, which could have the affected allele, to his daughters. Thus, any X-linked allele (either dominant or recessive) that is present in the father will necessarily be passed on to his daughters.
If the X-linked allele that the man carries is for a recessive trait, such as hemophilia or red-green color blindness, his daughters will be carriers of the trait. If the man has a X-linked dominant allele, his daughters will express the trait. The inheritance pattern is different for sons as they receive their X chromosome from their mother and the Y chromosome from their father. If the mother carries a recessive X-linked allele and the father does not, sons will have a 50% chance of inheriting the trait if they receive the affected X chromosome from their mother. Conversely, daughters will have a 50% chance of being carriers if they get the affected X from the mother.

A 23 year-old woman presents with sudden llq (left lower quadrant) pain which does not resolve. the decision is made to perform exploratory laparoscopy revealing a cyst on the left ovary. the cyst is removed along with a partial oophorectomy. what is/are the cpt® code(s) reported for this procedure?
Answer:
The answer is: 49321-51 and 58661
Explanation:
Report 49321 code for laparoscopy, surgical; with biopsy.
The 51 modifier is used when there are multiple procedures performed on the same session or are performed together.
Code 58661 describes partial or total oophorectomy and/or salpingectomy. Looking up ovarian cystectomy in the index of CPT, you are referred to code 58661 for that portion of the procedure also.
A 23-year-old woman's laparoscopy revealing an ovarian cyst and subsequent partial oophorectomy would be reported with a specific CPT code for billing. Laparoscopic surgery is used for less invasive procedures on ovarian disorders such as cysts.
A 23-year-old woman undergoing a laparoscopy to remove a cyst on the left ovary with subsequent partial oophorectomy would have a specific CPT (Current Procedural Terminology) code reported for this procedure. The code selection for the procedure depends on the specific details of the surgery performed. Healthcare providers select CPT codes for billing purposes to accurately describe the medical, surgical, and diagnostic services provided to the patient.
Ovarian cysts can occur as a common disorder and may require surgical intervention when they do not resolve on their own and cause significant pain. Laparoscopic surgery is a less invasive technique which uses instruments and a camera inserted through small incisions in the abdomen. A partial oophorectomy involves the removal of just part of an ovary, preserving some of the ovarian tissue and potentially maintaining hormonal and reproductive function.

There is a wide range of water pollutants usually influenced by humans. Water pollution is a huge problem that affects water ecosystems and their surrounding. Pollutants can be divided into two major groups, according to their source: point source pollutants (from a single source) and non-point source pollutants (from more different sources).
Agricultural and industrial pollutants-consequence of the use of fertilizers and pesticides; the pathogens are washed into the water together with nutrients (such as phosphorus and nitrogen) which lead to the algae blossom.The only way to limit and control this type of pollution is by government regulations.

radiactive, toxic substances, plastic bags are also the huge problem, especially in the oceanWhy is the trachea constructed with rings of cartilage
Answer:
Cartilage rings of trachea have protective role
Explanation:
Trachea is a tube, part of the respiratory system, which allows the passage of the air: from larynx to lungs (primary bronchi). It is enveloped with cartilage rings that prevent collapse of the trachea when there is no air. The cartilage "rings" are C-shaped, except one full ring-shaped - the cricoid cartilage which attaches trachea to the larynx.
The trachea is constructed with rings of cartilage to provide structural support that keeps the airway open, allows flexibility for breathing movements, and assists in coughing to expel foreign particles. The C-shaped cartilage is complemented by muscle and a soft membrane, ensuring both stability and adaptability.
Explanation:The trachea, commonly known as the windpipe, is designed with incomplete rings of cartilage for several crucial reasons. These C-shaped rings provide the trachea with structural support to stay open for air to pass through the respiratory tract. They are made of hyaline cartilage, which is strong yet flexible, enabling the trachea to expand and contract slightly during breathing.
The cartilage rings are connected by fibroelastic membrane and trachealis muscle, allowing for adjustments in the trachea's diameter; this is particularly useful during coughing, when the muscle contracts to push air forcefully through the trachea to expel mucus and foreign particles. Furthermore, the internal lining of the trachea is made of pseudostratified ciliated columnar epithelium and goblet cells, which trap particles and propel them away from the lungs through the action of cilia. This hybrid structure of rigid cartilage and flexible muscle ensures that the trachea remains patent and is capable of clearing inhaled debris efficiently.

Dissociative identity disorder is no longer controversial as the production of books and movies has raised a new understanding of the affliction.
Answer:
False
Explanation:
Dissociative identity disorder is a mental illness in which the person is diagnosed with having two or more different personalities with memory gaps or forgetfulness in between these different personality states. The disorder is a controversial one, and the movies and books focusing on the disorder have failed to reduce this controversy as these books and movies often associate the disorder with violence and crime and ignore other important aspects of the mental problem. The movies and books are often written and made to make the disorder seem more dramatic and hence, often revolve around thriller or horror genre and do not portray the personal struggle of the sufferers, the patients are actually tended towards hiding their disorder rather becoming too violent or dramatic as shown in the movies and written in the books.Hence the movies and books only heighten the controversy associated wit the disorder.What selective pressures might make the sickle cell mutation favorable? Where would this occur, and why?
Sickle cell mutation is most common in Africa and southern half of Europe. The reason for this is because, natural selection made areas with high concentration and history of diseases such as cholera, tuberculosis, yellow fever, and much more.
Answer:
Malarial selective pressure might make the sickle cell mutation favorable. This occurs in African population where malaria is endemic and this happens because the people who are heterozygotes for sickle cell anemia (HbA/HbS) are resistant to malaria so they survive the malarial parasite more successfully than either normal or sickle cell homozygotes.
Explanation:
Sickle cell anemia can be seen as an example of Balancing selection in areas where malaria is endemic. The people who are heterozygous for sickle cell anemia have only one copy of sickle cell allele (HbA/HbS). These people have better chances of surviving malaria because the malarial parasite spends a part of the life cycle in the RBC, if they enter into the RBC which are sickle shaped, they will die. The women who are heterozygous have higher fertility rates, that's why natural selection has not eliminated the allele. The loss of deleterious recessive genes through the death of people who are homozygous is being balanced by the high reproductive rates of women who are heterozygous in malaria prone areas. For this reason the selection is called balancing selection.
