Question

A pond, rich in various microorganisms, dries up due to drought. How will the amoeba in the pond protect themselves from this unfavorable condition?

A:By secreting a thick, protective sac around the cell membrane to prevent entry of water from the environment until favorable conditions emerge
B:By secreting a thick, protective wall around the cell membrane to prevent loss of water, forming a cyst until favorable conditions emerge
C:By secreting a thick cell wall which encloses many amoebae in it to prevent loss of water, forming a cyst until favorable conditions emerge

Answer 1

B: By secreting a thick, protective wall around the cell membrane to prevent loss of water, forming a cyst until favorable conditions emerge

Step-by-step explanation:

A is wrong because the purpose is to prevent water loss, not water entrance, which is the main thing amoeba need to protect themselves from

B is exactly correct, Edmentum confirmed

C is wrong because amoeba wouldn't be able to enclose itself with other amoeba and that doesn't seem beneficial

Answer 2
