Negative feedback serves a regulatory mechanism for reaction to avoid overproduction of a particular product.
<h3>What is negative feedback?</h3>
Negative feedback is a regulatory mechanism in which the products of a given reaction serves as inhibitor or regulator of a step in the reaction sequence so that more of the product is not produced.
Many enzymatic reactions in the body employ negative feedback for their regulation.
For example, high ATP concentration serves as negative feedback for glycolysis.

Answer
Use Mitosis to divide and create daughter cells.
Explanations
Single-celled organisms use mitosis to reproduce. Both growth and reproduction in unicellular organisms are mutually inclusive. When the cell’s volume grows, the ratio of surface area to volume decreases creating challenges in acquisition of nutrients because there will be too much cytoplasm for a given amount of nuclear material , thus the cell divides by mitosis to reproduce daughter cells and the process begins again.
The structures B and C have in common is that both contain partially disgested food. Thus, the correct option is B.
<h3>
What are structures B and C here represent?</h3>
Structure B represents the food pipe or esophagus, while structure C represents the stomach.
Chyme is produced only when food is fixed with gastric juice which is only present in the stomach, hence option A is incorrect.
Waste material is found in the rectum of the body structure, not in the esophagus and the stomach. Thus, option C is also incorrect.
Therefore, the correct option is B.

Answer:
Diseases that result from a homeostatic imbalance include heart failure and diabetes, but many more examples exist. Diabetes occurs when the control mechanism for insulin becomes imbalanced, either because there is a deficiency of insulin or because cells have become resistant to insulin.
