in which of these stages is mitosis most important?\na tiger cub is born.\na tiger cub learns to walk.\na…

Answer:

C. A tiger cub begins to grow.

Explanation:

Step1: Understand the role of mitosis

Mitosis is a process of cell division that results in two daughter cells each having the same number and kind of chromosomes as the parent nucleus. It is crucial for growth, repair, and asexual reproduction.

Step2: Analyze each option

• Option A: When a tiger cub is born, the major processes are related to birth - related physiological changes rather than extensive cell - division - based growth.
• Option B: Learning to walk is a behavioral and neuromuscular development process. It involves the coordination of muscles and nerves, not primarily mitosis - driven cell division for growth.
• Option C: When a tiger cub begins to grow, there is a need for an increase in the number of cells in its body. Mitosis is essential for this cell - number increase, which leads to overall growth in size (e.g., increase in body mass, length of bones and muscles etc.).
• Option D: Play - fighting is a behavioral activity. It mainly involves the use of existing muscles, nerves, and body structures, not a significant need for new cell production through mitosis for the activity itself.
