Does the DNA support the hypothesis that the coelacanth is the closest living relative to amphibians, such as frogs? If it does, explain how. If it does not, provide an alternative hypothesis suggested by the DNA data.

DNA does not support the hypothesis that coelacanth is the closest relative to amphibians.

Explanation:

After several DNA analyzes, including analysis of mitochondrial DNA sequences, scientists found that coelacanth DNA does not support the idea that it is the closest relative of amphibians. However, other molecular analyzes, looking at the DNA of other living beings, concluded that the pulmonary fish is, in fact, the closest relative of the amphibians, with Coelacanth being the closest relative of the tetrapods.

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.
