    The ability to live for some time without ingesting food
  • Correct answer
    B
    The ability to survive during adverse physical conditions
  • C
    The chance to get rid of accumulated waste products

    Protection from parasites and predators

Solution

During adverse environmental conditions, amoeba undergoes cellular and molecular changes, such as, change in cell structure, shape, water levels and creates a cyst membrane for the purpose of protection. When the environment is conducive again for survival, the protective envelope ruptures.
