There are 4 chromosomes that are visible at the beginning of Mitosis.
Answer - D. Mitosis (Confidently Correct)
Reasoning - Its basically the process when the chromosomes move during the ends of each section. Until then it becomes closed into a new cell.
Explanation:
The influence from radioactivity is inversely proportional to the number of chromosomes , since , humans have more DNA , chromosomes than the insects , and therefore , due to less chromosomes in insects , they are more resistant towards radioactivity .
As the target of the radiation is the DNA .
Hence , It is clear that insect due to lesser DNA are less prone to Radiations .

The Cretaceous period is the last period of the Mesozoic area where new groups of mammals, birds, and flowering plants appeared on Earth.
