2. A scientist is studying the fossils of giraffes from different regions and different time periods. What
would the scientist be most likely to learn about?
A. How the color of giraffes changed over time.
B. How the spots on giraffes changed over time.
C. How the height of giraffes changed over time.
D. How the behavior of giraffes changed over time.

C, because fossilisations would have no skin left. Therefore, A and B are ruled out because the colour and spots are all on the giraffe's skin.

It cannot be D because behaviour isn't recorded in fossils either.

Height is the most likely because it can also be a result of evolution and age, and the length of a giraffe's bones will determine its height.

your a sped   no one cares

i would go with b

cytokinesis occurs after telophase so that eliminates d

and the entire reason for cytokinesis is for cellular reproduction
