Answer:

D. All of the above

Explanation:

P53 is a tumor protein. It is often referred to as the "guardian of the genome". It can stop the cell from growing, repairs DNA and controls cell death, which is called apoptosis. As the cell is cycle goes on, p53 stops the growth of the cell when there is an error or damage in the DNA. This action prevents the defective cell from replicating. The p53 then signals the production of proteins that repair DNA. If the DNA is not fixable, it programs apoptisis.

If by some chance that the p53 gene are mutated, then it cannot do those functions, which may result in cancer or the uncontrolled replication of defective cells.

How do baroreceptor reflexes would respond to a fall in blood pressure?

RoseWind [281]

Answer:

Barroreceptors are specific type of receptors that are present within the membrane or wells of the blood vessels and monitor the changes occur in blood pressure.

The major and important barroreceptors are located in carotid sinus and the aorta for detecting fluctuation in the blood pressure. If blood pressure falls these receptors firing rate decreases and barroceptors reflexes act to increase heart rate in order to restore blood pressure in an individual.

Thus, the correct answer would be - increasing heart rate.
