Each codon of a DNA molecule code is for a specific __AMINO ACID__
Answer:
<u>1. type IV hypersensitivity: delayed-type hypersensitivity. </u>
<u>2. type I hypersensitivity: IgE </u>
<u>3. type II hypersensitivity: IgG </u>
<u>4. type III hypersensitivity: immune complexes </u>
Explanation:
Type IV hypersensitivity is cell mediated hypersensitivity rather than antibodies as in all other types of hypersensitivities. It is also known as delayed type hypersensitivity because it usually respond in 2-3 days via T-Lymphocytes rather than antibodies like IgE or IgG. So we can say that in option 5 is mismatched as it relates type IV to IgG antibodies.
Scientific validity is the applicability of a conclusion drawn in the context of a scientific experiment to the world at large.
Answer:
Tissue
Explanation:
The levels of organization go as follows:
Atom - the building blocks of all living and nonliving material
Molecule - two or more atoms that join together in chemical bond
Organelle - two or more molecules working together to perform a particular function in a cell
Cell - the smallest unit that exhibits all of the characteristics of life
<u>Tissue - two or more cells that work together to perform a particular function</u>
Organ - two or more tissues that work together to perform a particular function
Organ System - two or more organs that work together to perform a particular function
Multi-Celled Organism - two or more organ systems that work together
Answer:
The correct answer is: The ventromedial hypothalamus plays a role in satiety.
Explanation:
The hypothalamus is a part of the brain that controls many important bodily functions and connects both the nervous system with the endocrine system. The hypothalamus consists of several nuclei that have diverse functions and are located in 3 different regions.
The nucleus that plays a role in satiety is the ventromedial nucleus, terminating hunger and giving a sensation of fullness. It also plays a significant role in thermoregulation, among other things.
Neuropeptide Y, on the other hand, is a peptide that is released to make us feel hungry and encourage us to intake food (primarily carbohydrates).
Cholecystokinin is a hormone released by the small intestines after we had a meal, and its function is to improve digestion and make us feel full.
Fat cells DO release leptin, but the function of this hormone is to produce satiety, by stimulating anorexigenic (meaning they take hunger away) hormones and inhibiting orexigenic ones, like Neuropeptide Y.
