Which hypothesis do the similarities in the bone arrangements support? a. These organisms are members of the same species.

b. These organisms may have descended from the same ancestor.

c. These organisms have adaptations to survive in different environments.

d. These organisms all contain the same genetic information.

B

Explanation:

A similarity in the arrangement of bones in organisms can be hypothesized to be an indication of the organisms descending from the same ancestor.

The similarity in the arrangement of bone in different organisms is one of the morphological evidence used to support the theory of organic evolution which says that all living organisms are of the same descent with modification from common ancestors.

The similarity in the arrangement of bones falls under homology. Homologous organs are similar in structures but different in functions. For example, the pentadactyl limbs of vertebrates. Mammals, birds, reptiles, and amphibians all have limbs that are built on a five-digit plan but the functions of the limb vary within and among different groups of vertebrates.

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.

answer; the correct answer is (beta)
