Answer:
100 units
Explanation:
The parent cell holds 200 units of DNA. During the process of cell division, this amount is distributed between the resulting daughter cells, with each cell obtaining half of the DNA present in the original cell.
As mitosis yields two daughter cells, each one will receive 100 units of DNA.
When stimulated, the stomach's environment is characterized as acidic. It secretes protease enzymes and hydrochloric acid to assist digestion. The hydrochloric acid keeps the pH low, enabling protease enzymes to effectively break down proteins. Following digestion, the stomach returns to its normal pH level. Therefore, acid secretion coincides with food presence to support proper digestion.
