The correct order according to the size will be - the nucleus of an atom, ribosome, nucleus of a cell, or a human cell.
What is meant by classification?
In terms of biology, classification is defined as basic categories of organisms by their presumed natural relationships. This is used to create taxonomical groups.
The study of the interactions and behaviour of the components of biological materials which include molecules, cells, organs, and organisms is called systems biology.
The organisation of all biological organisms has been a lasting interest in the field of science. Systems biology emerged from the genomics revolution as a separate field of study. This was the beginning of the Human Genome Project.
Therefore, in the terms of classification according to size, the nucleus of an atom will be the smallest, the ribosome will be bigger, the nucleus of a cell will be bigger than the ribosome and the human cell will be the biggest.

The active ingredient in marijuana, tetrahydrocannabinol (thc) is stored in the body's ________ cells.
THC, the active ingredient in marijuana, is stored in the body's fat cells.
Explanation:The active ingredient in marijuana, tetrahydrocannabinol (THC), is primarily stored in the body's fat cells. THC is a lipid-soluble molecule, meaning it can easily dissolve in fat. When someone consumes marijuana, THC is absorbed into the bloodstream and eventually accumulates in fatty tissues throughout the body, including the brain, liver, and adipose tissue.
Because THC is stored in fat cells, it has a long elimination half-life compared to other drugs. This means that THC can remain detectable in the body for an extended period, even after the immediate effects of marijuana have worn off.
In summary, THC is stored in the body's fat cells, allowing it to be gradually released into the bloodstream over time.

Trichodesmium is a nitrogen-fixing cyanobacteria. Why might this cyanobacteria be important to other organisms in nitrogen-poor waters?
Answer:
The answer is Trichodesmium is an important source of usable nitrogen in the nutrient-poor waters and represents almost half of the nitrogen fixation in marine systems.
Explanation:
Nitrogen fixation is the process of converting atmospheric diatomic nitrogen into biologically usable forms of nitrogen, such as ammonium oxides and nitrogen. Trichodesmium is the only known diazotropic capable of fixing nitrogen in daylight in aerobic conditions, being the main diazotropic in marine pelagic systems and an important source of usable nitrogen in the nutrient-poor waters where it lives. Trichodesmium fixes nitrogen on a scale that represents almost half of the nitrogen fixation in marine systems worldwide.
What is the outcome of mitosis?
A. two identical nuclei
B. two identical spindles
C. two identical chromatids
Answer:
The correct answer is option A. two identical nuclei.
Explanation:
Mitosis is a type of cell division during which two identical daughter cells are produced from a single parent cell.
During mitosis, replicated chromosomes are divided into 2 new nuclei, It gives rise to identical cells with the same number of chromosomes.
During interphase, DNA of the cell is replicated and at the last of interphase, the original DNA and a copy of this DNA are in the nucleus of the cell.
In the M phase or mitotic phase, the nuclear DNA of the cell condenses into chromosomes and is pulled apart by the mitotic spindle, made out of microtubules. Four phase takes place during mitosis: prophase, metaphase, anaphase, and telophase. IT results in two identical daughter cells after cytokinesis.
Thus, the correct option is two identical nuclei.
The outcome of mitosis is two identical nuclei
What is the outcome of mitosis?The outcome of mitosis is the division of a cell into two daughter cells, each containing an identical set of chromosomes. During mitosis, the replicated chromosomes are separated and distributed equally into the daughter cells, resulting in the formation of two identical nuclei. This process ensures that each daughter cell receives the same genetic information as the parent cell, allowing for growth, tissue repair, and asexual reproduction in organisms.

A healthcare provider prescribes a diagnostic workup for a client who may have myasthenia gravis. what is the initial nursing objective for the client during the diagnostic phase?
Final answer:
The initial nursing objective for a client being diagnosed with myasthenia gravis is to ensure safety, manage symptoms, and support during diagnostic tests. Nurses must focus on assessing respiratory function, swallowing, applying the 'assess, document, re-assess, and advocate' strategy, educating the client, and monitoring responses to diagnostic interventions.
Explanation:
Initial Nursing Objective for Myasthenia Gravis Diagnostic Phase
The initial nursing objective for a client undergoing a diagnostic workup for myasthenia gravis is to ensure the client's safety and to manage symptoms during the diagnostic tests. Myasthenia gravis is an autoimmune disorder that affects the neuromuscular junction, leading to a reduction in the number of acetylcholine receptors and resulting in muscle weakness. During the diagnostic phase, it is crucial that nurses assess and monitor the client's respiratory function and ability to swallow, as these can be significantly affected by muscle weakness. The application of the “assess, document, re-assess, and advocate” strategy ensures a thorough evaluation of symptoms and effective communication with the healthcare provider for timely intervention.
It is also imperative for the nurse to educate the client on the nature of the diagnostic tests, such as the administration of an inhibitor of acetylcholinesterase, which can temporarily restore muscle contractility by allowing more acetylcholine (ACh) to remain at the neuromuscular junction. Monitoring the client's response to these tests is essential for accurate diagnosis and to facilitate the initiation of an appropriate treatment plan.

Bacteria need the right kind of food to grow on. generally, they prefer foods that are high in protein, slightly acidic, and _______.
Bacteria optimally grow on high-protein, slightly acidic, and moist substances.
Explanation:Bacteria grow best on substances that are rich in protein, slightly acidic, and moist. Moist environments help bacteria to maintain the necessary solute concentration within their cells and they also aid in the transport of nutrients into the cell. Foods that contain a high protein content include meat, which makes it a prime substrate for bacterial growth.
The acidity level in foods is essential for bacterial survival. Most bacteria cannot survive in highly acidic environments, and hence they prefer slightly acidic foods. This is one reason why foods like lemon and vinegar can be used as natural preservatives to slow the growth of bacteria.
Cellular processes such as respiration and excretion also occur more efficiently in moist conditions. In summary, bacteria are microorganisms that prefer high protein, slightly acidic, and moist environments to grow best.

The entry of bile and pancreatic juice into the duodenum is controlled by
The hepatopancreatic sphincter (sphincter of Oddi) regulates the entry of bile and pancreatic juice into the duodenum. The hormones secretin and CCK, along with the parasympathetic nervous system, control the secretion of these fluids that are essential for digestion.
The entry of bile and pancreatic juice into the duodenum is controlled by the hepatopancreatic sphincter, also known as the sphincter of Oddi. This sphincter acts as a gatekeeper to regulate the flow from the bile duct, carrying bile from the liver, and from the main pancreatic duct, carrying pancreatic juice from the pancreas. The release of digestive enzymes, alkaline bicarbonate, and bile into the duodenum is a crucial process for neutralizing acidic chyme and aiding in the digestion of fats, proteins, and starches.
The hormones secretin and cholecystokinin (CCK) play significant roles in this regulatory process. Secretin is released when acidic chyme enters the duodenum, prompting the pancreas to release bicarbonate-rich pancreatic juice. CCK, on the other hand, is stimulated by the presence of proteins and fats in the duodenum, leading to the secretion of enzyme-rich pancreatic juice and the contraction of the gallbladder to release bile. Lastly, the parasympathetic nervous system, through vagal stimulation, also influences pancreatic secretion during the cephalic and gastric phases of gastric secretion.

Emts respond to a known heroin abuser who is unresponsive. if they give naloxone (narcan) to this patient, the emts should recall that:
Answer:
Naloxone/Narcan administration may cause agitation and/or withdrawal symptoms.
Explanation:
Remember that the main purpose of administering Narcan/Naloxone is to correct respiratory depression in a patient. Prior to administering the medication, a patient must meet three primary criteria:
1. Pinpoint pupils ( evident in a patient with Opiod overdose)
2. Unconsiousness
3. Respiratory depression (cannot breath on their own)
Once those three criteria have been confirmed, under medical control guidance, you can administer Narcan/Naloxone (per proper packaging instructions).
The purpose of this medication is NOT to bring someone out of uncounsiousness. However, if too much is administered, there is a significant chance that the patient can become consious. Therefore, the patient can eitherr be 1) combative and angry because you "took him/her out of their high" or 2) they can be grateful that you helped them out. That being said, you want to be aware that if the patient is combative, your safety is at risk and you will need to involve law enforcement.
Hope this helps!
