Question

question 8
the first sign of cytokinesis in an animal cell is the formation of a:
a cell plate
b cleavage furrow
c cell wall
d nucleolus
e nuclear envelope

Explanation:

Cytokinesis in animal cells starts with the formation of a cleavage furrow. A cell - plate forms in plant cells during cytokinesis. Cell walls are a feature of plant, fungal, and some prokaryotic cells, not related to the start of animal - cell cytokinesis. The nucleolus and nuclear envelope are related to nuclear processes and not the initial sign of cytokinesis in animal cells.

Answer:

B. Cleavage furrow
