Answer:
D
Explanation:
Atoms and molecules are the smallest units of matter.
The condition of the AIDS (Acquired Immunodeficiency
Syndrome) is caused by a virus called HIV (Human Immunodeficiency Virus). The
virus itself attacking the definite type of immune system cell inside the body.
Its cell also known as the helper cells or CD4 helper lymphocyte cells particularly
in the adaptive immune system. HIV ruining these cells, it’ll make so hard for
the body to combat off and guard off other infectious diseases. When people
gets HIV, even slight infection like fever or colds can be much critical
because the body itself has difficulty healing. Hence, immune system of one’s
person will be lowered because the helper cells are slowly being destroyed and it
makes the person unsafe.
The nervous and the endocrine system are tightly linked together.
The main reason for this linkage is due to the connection of the hypothalamus (nervous system) and the hypophysis (a gland in the endocrine system)
The hypophysis is the ''controller'' of all of the other endocrine glands.
The connection between the hypothalamus and the hypophysis enables the nervous system to control the hormone levels of all of the major endocrine glands in the body.
The hypothalamus releases hormones into the bloodstream that leads to the hypophysis. These hormones induce a release of hypophysis hormones that enter the bloodstream and when they reach the target gland (for example pancreas) these hormones induce the release of the hormones of that gland (in the case of the pancreas, insulin).
The hypothalamus monitors the concentration of hormones in the blood, and a high level of a certain hormone blocks the release of the hypothalamus' hormones. Therefore, a high level of insulin blocks a cascade of hormone release that starts in the hypothalamus that leads to its release in the pancreas.
Answer:
Phenylketonuria results from the deficiency of the enzyme phenylalanine hydroxylase
Explanation:
Phenylalanine hydroxylase converts phenylalanine to tyrosine. Deficiency of this enzyme leads to accumulation of phenylalanine leading to the disorder known as phenylketonuria
