Question 16 of 20: select the best answer for the question. 16. an amoeba moves by pushing out small projections called rest of the organism along. and then pulling the o a. bacterial conjugates o b. spores o c. pellicles o d. pseudopodia mark for review (will be highlighted on the review page) < < previous question next question > >

D. pseudopodia

Explanation:

The pseudopods are one of the modes of locomotion of unicellular organisms. The amoebas move forming a large pseudopod at the front of the cell, while the cytoplasm retracts from the back and repeats this process, or by extending and contracting several small pseudopods that, in contact with the substrate, allow displacement.

well, that's easy; the answer's c, "it reduces contamination of the water and substrate of the estuary."
