- Bthe ability to live for some time without ingesting food
- Cprotection from parasites and predators
- Dthe chance to get rid of accumulated waste products
Correct answer
A. the ability to survive during adverse physical conditions
Step-by-step solution
During adverse environmental periods, Amoeba survive by encystment by becoming circular, loses most of its water, and secretes a cyst membrane that serves as a protective covering. When the environment is again suitable, the envelope ruptures and the Amoeba emerges. Related Theory During unfavourable conditions, Amoeba undergo multiple fission inside the cyst to survive and reproduce under unfavourable conditions. In the multiplefission, the nucleus of the parent cell divides multiple times by amitosis (direct cell
