Cells need mitosis in order to keep the supply of cells suitable for the human body to continue circulating with
<u>Answer</u>: c. Carrying capacity is the maximum population size required for a particular species in a particular area to survive.
<u>Explanation</u>: this is an average population density level. If the population density is above this level, the number of individuals will decrease. If the population density is under this level, the number of individuals will increase until the carrying capacity is reached once more.
Answer:
A. INACTIVE PRECURSOR OF THE ENZYME PEPSIN THAT DIGESTS PROTEINS IN THE STOMACH.
Explanation:
Pepsinogen is the inactive precursor of pepsin produced by the chief cells of the stomach lining. The stomach walls are lined by majorly two types of cells; the chief and the parietal cells. Chief cells secretes pepisinogen and parietal cells secrete hydrochloric acid in the stomach lining. The chief cells upon the signals of increased protein substance in the stomach produces pepsinogen which upon it release, it is activated to the active enzyme Pepsin by the hydrochloric acid from the parietal cell. Hydrochloric acid provides the acidic environment needed for the action of pepsin in the stomach. The pepsin begins the digestion of proteins into small amino acids in the stomach,
