@amistre64 @Directrix @SolomonZelman @ParthKohli @pooja195 @Loser66 @AlexandervonHumboldt2 @Cardinal_Carlo Can you guys help??

Answer 3

Just because something is aquatic does not mean it's multicellular -- take for example, plankton. We can cross out A.

Answer 4

Just because something is motile does not necessarily mean it's multicellular -- take for example, bacteria or amoeba. We can cross out D.

Answer 5

Symmetry does not equate multiplicity. We can eliminate C.

Answer 6

The only answer that's left is B. Prokaryotes (the most common unicellular organisms) lack a membrane-bound nucleus and membranous organelles. B is your best answer @I_Ask_Alot.

Answer 14

Prokaryotes lack a nucleus. So, to compensate, they have a designated space within their cells called a nucleoid (a "mock" or "mimicry" of a nucleus) to hold their genetic material (i.e. plasmids). So your best answer is D @I_Ask_Alot.
