Answer:
A. Activated B - cells divide to form memory cells.
Explanation:
The vaccine contains the dead version of the respective virus, so that virus will be inactive and it will become easy for the WBC to kill it and antibodies will be formed.
This is done because if we get infected by the virus, our body cells (WBC) will remember that how they killed the first entered virus (the dead version) and it will be easy for them to kill the active virus as they know the antibodies which were formed to kill the inactive virus.

Explanation:
If the population of prey species decreases then the competition between the predator population will increase and natural selection will act on them. So nature will select those individuals among predators who are more fit and adapted and less fit individuals will die.
So a few year after the predator population will decrease as there are not enough prey to support the large population of predators which was present when prey were abundant. Therefore the correct answer is D.
The cell cycle is controlled by many cell cycle control factors, namely cyclins, cyclin-dependent kinases (Cdks) and cyclin-dependent kinase inhibitors (CKIs). Cyclins and Cdks, which are positive regulators of the cell cycle, activate cell cycle factors that are essential for the start of the next cell cycle phase.
