its a gene that you either receive from your mother or father.
Answer:
d. Epithelial tissues are nourished by blood vessels in adjacent tissues, thus diffusion is limited to thin tissues.
Explanation:
Epithelial tissues have tightly packed cells and have no space for blood vessels to be present between adjacent epithelial cells. The cells of the epithelial tissues get nutrients from the blood vessels of neighboring connective tissues.
Since the exchange of nutrients between the cells of the epithelial and connective tissues occurs through diffusion, epithelial tissues are only one to few cells layers thick to allow nutrient supply to all of its cells.

The enzyme that is present within the stomach and the lining of the muscular gland, would function optimally in high H+ concentration and would require much HCl needed for an appropriate pH environment to function
This would be pepsin, I believe.
Answer:
They are genetically identical to the parents and only differ if a genetic mutation occurs.
Sexual reproduction involves two parents and produces offspring that are genetically unique.
The greater the genetic variation, the better change that an individual in the population have a favorable gene that can help survival. Genetic variation is an important force in evolution as it allows natural selection to increase or decrease frequency of alleles already in the population.
