Answer: This is a positive feedback loop.
Explanation:
The protein digestion in the body is an example of the positive feedback. The gastric secretions is stimulated chiefly by the action of three chemicals.
These chemicals are acetylcholine, histamin and gastrin. These chemicals stimulate the parietal cells to secrete HCL and intrinsic factors.
The chief cells secrete pepsinogen in response to the gastrin and ACh. As the dietary proteins are digested, it breaks down the amino acids and peptides.
This stimulates the G cells of the stomach to secrete more gastrin. This is how the positive feedback loop for the protein digestion works.
In a red blood cell, the control center is the nucleus. A mitochondria is not a nucleus. It is another organelle that produces energy for the cell.

<u>Answer:</u>
The sequence of the bases in DNA is most important because it provides the instructions for the traits of an organism.
<u>Explanation:</u>
- 'Deoxyribonucleic Acid (DNA)' is an instruction carrier. DNA stores the information and passes it from one generation to another.
- It stores all the information that helps in growth, development and different characteristics developments.
- So, the 'sequence of DNA bases' is important to be transferred during the reproduction that transfers the characters from parents to children.
