an overaccumulation of dinoflagellates causes a ______, which can contaminate shellfish and make them unfit for human consumption.
a) scarlet wave
b) crimson summer
c) red tide

Explanation:

First Question (Amoeba Movement)

Amoebas move using pseudopodia (false feet), temporary projections of cytoplasm. Pellicles are protective layers in some organisms, bacterial conjugates relate to bacterial reproduction, and spores are reproductive structures—none relate to amoeba movement.

Second Question (Dinoflagellate Accumulation)

Overaccumulation of dinoflagellates (often with red pigments) causes red tides, which contaminate shellfish. "Scarlet wave" and "crimson summer" are not scientific terms for this phenomenon.

Answer:

C) pseudopodia
