Answer: The correct answer is-
an agent that causes a mutation in DNA.
Mutagen is an agent or a substance that causes permanent change in the genetic material of living organisms ( DNA, deoxyribonucleic acid). This process is called mutation.
A mutagen can be a chemical, physical or biological agent that causes mutation in the DNA.
Example- Physical agents such as -
- Ionizing radiations like alpha particles, gamma rays, X-rays that brings break in the DNA and cause other damages.
- Ultraviolet radiations that creates pyrimidine dimers ( T=T) and causes replication errors if damage is not repaired.
The correct answers (c.) punctuated equilibrium.Punctuated equilibrium is a mode of evolution that the certain foraminifera (shelled protozoa) represents. It is , in fact, the hypothesis of the evolutionary development of rapid episodes that is marked between long periods of little or even with no change at all.

Answer:
Pons.
Explanation:
Inside of our brainstem, there is a structure which is called the pons, which is present besides the medulla oblongata. The pons is a significant structure in the upper part of our brainstem. It controls breathing, communication between different parts of the brain, and as well as sensations such as hearing, taste, and balance.
Pons is that part of the brainstem which carries one-way communications that advise the cerebellum of voluntary motor activities initiated by the motor cortex.
