Answer:
The correct answer is b. phenylketonuria (PKU)
Explanation:
Phenylketonuria (PKU) is a genetic disorder in which an amino acid called phenylalanine accumulates in the body. It occurs due to the mutation in a gene that codes for an enzyme called phenylalanine hydroxylase.
This enzyme is necessary for breaking down the phenylalanine in the body. As in phenylketonuria (PKU), this enzyme becomes defective so dietary phenylalanine starts accumulating in the body which cause this disorder.
Some symptoms of this disease are neurological problems, rashes on the skin, hyperactivity, behavioral disorders, etc. So the correct answer is b.
Answer:
The simplest mechanism by which molecules can cross the plasma membrane is passive diffusion. Passive diffusion is thus a nonselective process by which any molecule able to dissolve in the phospholipid bilayer is able to cross the plasma membrane and equilibrate between the inside and outside of the cell.
The answer is:
The study of tissue is known as histology. To go more in depth, the study of the disease of tissues is known as histopathology.
