Answer:
If the immune system has a destructive and autoimmune response, it produces specific antibodies, which bind to the receptors of the thyroid cells and destroy them thinking that they are antigens or factors not characteristic of the body.
Explanation:
This happens because the thyroid cells do not present on its surface the histocompatibility complex, which is a surface protein similar to the proper and non-proper "seal", that is, it is the demarcation by which the antibodies and the cells are guided to recognize what foreign to the organism.
The histocompatibility complex is sometimes absent or rather mutated, thus generating that these cells are considered not their own and that the antibody is a receptor in order to generate the autolysis pathway or even the immune defense pathway.
Answer: C) Prokaryotes convert nitrogen-containing molecules into forms that can't be used by other organisms.
Prokaryotes are the organisms that do not have a membrane bound nucleus, mitochondria and other organelle. They ranges in size of diameter from 0.1–5.0 µm.
Example:<em> Escherichia coli, Sulfolobus acidocaldarius archeobacterium </em>
Decomposers, play an important role in nitrogen cycle. Nitrogen gas is converted to nitrate compound by nitrogen fixing bacteria which are present in root nodules of leguminous plants.
Example: <em>Azotobacter </em>
Answer:
The correct answer is hypophysis or pituitary.
Explanation:
The pituitary gland is at the size and shape of a pea and is also known as the master gland because it controls and stimulates the regulation of other endocrine glands. The pituitary gland is itself an endocrine gland which secretes its hormone directly in the blood.
Some hormones released by pituitary that stimulate other endocrine gland are adrenocorticotropic hormone (ACTH) which stimulate the adrenal gland to release cortisol. FSH and LH hormone that stimulate testes and ovary in male and female, Thyroid-stimulating hormone (TSH) which stimulate thyroid gland, etc. Therefore the right answer is pituitary.
