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.
You are supposed to answer what happens in each phase of meiosis.
People with O+ blood cannot donate their blood to negative blood types, while people with O- blood can donate to any blood type. This makes them the "universal donor." However, they can only receive O- blood.

Both X and Z will increase in order.
Option D.
<h3><u>Explanation:</u></h3>
Here in the question we can see that all the three compounds X Y and Z are in equilibrium as they are put in a water beaker containing water. This phenomenon is Called chemical equilibrium when the substances that are isomers to each other actually forms in water and their relative concentration remains in a particular ratio according to their stability.
Here in the question, the solution contains X Y and Z in equilibrium. But if more Y is added in the solution, firstly the equilibrium constant for X and Y will get disrupted because X will get low in amount with respect to Y. So some Y will get converted to X. Similarly, when Z will also face the same problem and some Y will get converted to Z. Hence the amounts of both X and Y will increase along with Y.
