If organisms A, B, and C belong to the same class but to different orders and if organisms C, D, and E belong to the same order but to different families, which of the following pairs of organisms would be expected to show the greatest degree of structural homology?1. A and D2. B and D3. B and C4. D and E

D and E

Explanation:

As we move from a higher rank to a lower rank in the taxonomic hierarchy, the degree of similarities increases.i.e. the degree of similarities increases from kingdom to species. Species contain the individual who are most similar and can interbreed among themselves.

Since, A , B and C belong to same class while  C, D and E belong to same order, the degree of similarity between C,D and E will be more than that of the degree of similarity between A, B and C.

Again since C belongs to the class of A and B ,it will be more distant from D and E.

Thus D and E will be more similar than D and C or E and C.

i would go with b

cytokinesis occurs after telophase so that eliminates d

and the entire reason for cytokinesis is for cellular reproduction
