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?A) A and D
B) B and D
C) B and C
D) D and E

D and E

Explanation:

The organisms are classified on the basis of their similarities and dissimilarities.

The taxonomic ranks are: Kingdom > Phylum> class > Order > family > genus > species.

As we move from kingdom towards the species the degree of similarities increases  i.e.  organisms that are grouped within a kingdom may have greater number of dissimilarities among them again more similar organisms are grouped into phylum, further organisms  whuich are more similar within a phylum are grouped into class and this goes on.

In a species the individuals are very similar and have least number of dissimilarities among them.

In the given situation, A,B and C are of same class But they are in different order but C,D and E are of same order.

So C is more similar to A and B when compared to D and E.

Thus, D and E  are expected to show greatest degree of structural homology.

correct answer is option a.

tropopause, stratopause and mesopause have all in common aspect that is point of maximum temperature in its layer of the atmosphere. all layers of atmosphere observe abrupt change in temperature. tropopause is the boundary between troposphere and stratosphere. stratopause is the boundary between stratosphere and mesosphere. mesopause is the boundary between mesosphere and thermosphere. these all boundaries are ranges between altitude of 0 to 80 km.

the answer is: reproductively

i think i spelled it wrong lol

anyways hope i
