Question

question 21 of 25
the image shows a unicellular organism called a paramecium.

how are the parameciums cilia a structural adaptation?

a. they are actions that an organism takes that make the organism more likely to be eaten by predators.

b. they are actions that an organism takes to help the organism perform cell division.

c. they are physical features that help the organism survive by allowing it to make food through photosynthesis.

d. they are physical features that help the organism survive by allowing it to move around and get food.

Explanation:

Cilia are physical structures (not actions, eliminating A and B). Paramecium is not photosynthetic (eliminating C). Cilia help in locomotion (moving around) and also in directing food (like bacteria) into the oral groove, which aids in getting food, thus helping survival.

Answer:

D. They are physical features that help the organism survive by allowing it to move around and get food.
