According to the passage, platelets are LEAST likely to contain:
A transmembrane serotonin transporters.
B ribosomes.
C serotonin.
D Ki67.
Passage: "Platelets carry 95 percent of blood serotonin, which is synthesized from tryptophan and secreted by endocrine cells in the lining of the gastrointestinal tract. Researchers experimentally tested the hypothesis that platelet serotonin is responsible for the platelets’ positive effect on hepatocyte proliferation. The number of hepatocytes expressing the Ki67 protein, which is detected exclusively in the nuclei of proliferating cells, was used as a measure of liver regeneration."
Answers
Platelets are least likely to contain serotonin. Platelets are small, colorless cell fragments that are involved in blood clotting. They are also known to contain various proteins and growth factors that play an important role in tissue repair and regeneration. One of these factors is serotonin, which is synthesized and stored in platelets. However, according to the passage, platelets are least likely to contain serotonin.
This is because platelets carry 95% of blood serotonin, which means that most of the serotonin in the body is found in platelets. The researchers in the study hypothesized that platelet serotonin is responsible for the platelets' positive effect on hepatocyte proliferation.
They measured the number of hepatocytes expressing the Ki67 protein, which is a marker of cell proliferation, and found that platelet serotonin indeed plays a role in liver regeneration. Therefore, platelets may not be a good source of serotonin for other purposes, as they contain very little of it compared to the total amount in the body.

How are eating disorders similar to other mental illnesses
Answers
Answer:
Explanation:
Co-occurring disorders are defined as having 2 or more mental health or substance abuse disorders at one time and was formerly known as dual diagnosis. The term dual diagnosis is no longer used as the word “dual” often refers to two where individuals may have more than two disorders occurring at the same time. More often than not individuals will only be treated for their specific eating disorder and their depression or anxiety goes untreated. This is problematic because their depression or anxiety could be the underlying problem driving the eating disorder. If the depression or anxiety remains untreated then the individual has a higher chance of relapsing and falling back into their binging and purging behavior. The following are co-occurring disorders that are commonly found with eating disorders:
A deficiency in thiamine causes the disease beriberi. Which might you expect to be higher than normal blood concentration in an individual with this condition?.
Answers
Pyruvate will be increase since the thiamine deficiency would prevent the transformation of pyruvate to acetyl CoA due to the lack presence of the pyruvate dehydrogenase. thus the answer should be Pyruvate.
Pyruvic acid has a carboxylic acid and a ketone functional group, making it the most basic of the alpha-keto acids.
The conjugate base, pyruvate, is an intermediary in several metabolic pathways throughout the cell.
Pyruvic acid can be synthesized from glucose by glycolysis, converted back to carbohydrates (such as glucose) via gluconeogenesis, or transformed to fatty acids via an acetyl-CoA process.
It may also be used to synthesize the amino acid alanine and fermented into ethanol or lactic acid.
When oxygen is present, pyruvic acid supplies energy to cells via the citric acid cycle (also known as the Krebs cycle), and when oxygen is not present, it ferments to produce lactate.

Axonal degeneration in CNS vs. the PNS? (review)
Answers
CNS axonal degeneration from myelin damage, PNS from injury.
What causes axonal degeneration?Axonal degeneration refers to the destruction or breakdown of axons, the long fibers that transmit electrical impulses between nerve cells. This process can occur in both the central nervous system (CNS) and peripheral nervous system (PNS), but the mechanisms of degeneration differ between the two.
In the CNS, axonal degeneration is mainly a result of damage to the myelin sheath, the protective covering around the axon. This damage can be caused by a variety of factors, including trauma, inflammation, or disease.Once the myelin sheath is damaged, the axon is exposed and vulnerable to further damage. Inflammatory cells, such as macrophages, can enter the damaged area and release toxic substances that cause the axon to degenerate.In contrast, axonal degeneration in the PNS typically occurs as a result of injury or trauma to the nerve itself. When a nerve is damaged, the axon distal to the injury site undergoes a process called Wallerian degeneration. This involves the breakdown of the axon and its associated myelin sheath, as well as the fragmentation of the Schwann cells that produce the myelin.In both the CNS and PNS, axonal degeneration is accompanied by a series of cellular and molecular events that contribute to the process. These include the activation of certain enzymes, the release of cytokines and other signaling molecules, and the recruitment of immune cells.Despite the differences in the mechanisms of degeneration between the CNS and PNS, there are some similarities in the ways that axons can regenerate after injury. In both systems, axonal regrowth is limited by a variety of factors, including scar formation and inhibitory signals from the surrounding tissue. However, researchers are exploring new strategies to promote axonal regeneration and functional recovery after injury.axonal degeneration in the CNS and PNS involves different mechanisms, with damage to the myelin sheath being a primary factor in the CNS and physical injury being the primary factor in the PNS. However, there are some commonalities in the cellular and molecular events that occur during degeneration, and new approaches are being developed to promote axonal regeneration in both systems.

Answers
Answer:What is biometrics?
Biometrics is the measurement and statistical analysis of people's unique physical and behavioral characteristics. The technology is mainly used for identification and access control or for identifying individuals who are under surveillance. The basic premise of biometric authentication is that every person can be accurately identified by intrinsic physical or behavioral traits. The term biometrics is derived from the Greek words bio, meaning life, and metric, meaning to measure.
How do biometrics work?
Authentication by biometric verification is becoming increasingly common in corporate and public security systems, consumer electronics and point-of-sale applications. In addition to security, the driving force behind biometric verification has been convenience, as there are no passwords to remember or security tokens to carry. Some biometric methods, such as measuring a person's gait, can operate with no direct contact with the person being authenticated.
Components of biometric devices include the following:
a reader or scanning device to record the biometric factor being authenticated;
software to convert the scanned biometric data into a standardized digital format and to compare match points of the observed data with stored data; and
a database to securely store biometric data for comparison.
Biometric data may be held in a centralized database, although modern biometric implementations often depend instead on gathering biometric data locally and then cryptographically hashing it so that authentication or identification can be accomplished without direct access to the biometric data itself.
Types of biometrics
The two main types of biometric identifiers are either physiological characteristics or behavioral characteristics.
Physiological identifiers relate to the composition of the user being authenticated and include the following:
facial recognition
fingerprints
finger geometry (the size and position of fingers)
iris recognition
vein recognition
retina scanning
voice recognition
DNA (deoxyribonucleic acid) matching
digital signatures

which of the following statements regarding anaphylaxis is correct?
Answers
The correct statement regarding anaphylaxis is: Anaphylaxis is characterized by airway swelling and hypotension.
Anaphylaxis is a severe and potentially life-threatening allergic reaction that occurs rapidly after exposure to an allergen. It is characterized by a combination of symptoms involving multiple systems in the body. One of the key features of anaphylaxis is airway swelling, which can lead to difficulty breathing, wheezing, and shortness of breath.
Additionally, anaphylaxis can cause hypotension, which is low blood pressure. This drop in blood pressure can result in dizziness, lightheadedness, and even loss of consciousness. Other common symptoms of anaphylaxis include hives, itching, flushing, gastrointestinal disturbances (such as nausea, vomiting, and diarrhea), and a sense of impending doom.
It is important to note that anaphylactic reactions can occur at any time after exposure to an allergen and are not limited to a specific timeframe.

Group of answer choices
Patients with asthma are at lower risk of developing anaphylaxis.
Anaphylaxis is characterized by airway swelling and hypotension.
Most anaphylactic reactions occur within 60 minutes of exposure.
The signs of anaphylaxis are caused by widespread vasoconstriction.
Anaphylaxis is a severe allergic reaction leading to a drop in blood pressure and bronchial contraction. It can be caused by allergens such as shellfish or penicillin and is typically counteracted with the administration of epinephrine. Individuals prone to anaphylaxis are recommended to carry epinephrine injectors.
Explanation:Anaphylaxis is a potentially life-threatening systemic type I hypersensitivity reaction caused by allergic responses. The allergic reactions can cause a sudden drop in blood pressure, also known as anaphylactic shock, and constriction of bronchial smooth muscles, leading to respiratory distress, potentially fatal if untreated. Common allergens that provoke such strong allergic responses are usually nonpathogenic substances such as shellfish, peanuts, or even certain medications like penicillin that are ingested, inhaled, or injected.
Upon exposure to the allergen in susceptible individuals, systemic mast cell degranulation occurs, leading to the allergic response. To counteract this, epinephrine is employed to raise both blood pressure and relax bronchial smooth muscle. People with known severe allergies are advised to carry automatic epinephrine injectors with them, especially in places with limited access to immediate medical attention.
