The correct answer is: it releases sweat to cool down.
During the exercise, body temperature increases and as a result respiration releases energy in the muscles, the skin produces sweat, which evaporates from the surface of the skin. Evaporation takes heat energy from the body.
Energy needed to perform exercise is derived from anaerobic metabolism within the cytosol of muscle cells (anaerobic respiration).
The similarity of 94% in their DNA sequence suggest that they have originated from a common ancestor and are closely related species.
Explanation:
The difference in DNA sequences in different species is due to the accumulation of genetic variation in the course of natural selection and evolution. Less is the difference in DNA sequences of two organisms the more related they are.
Genes determine the characteristics in an organism, and they are DNA sequences determining the protein to be formed. The similarity in DNA sequence of two species establish the evolutionary relationship among them.
Due to the genetic variation in species, the natural selection of the species had caused the evolution of the species adapted well to the environment.
D is incorrect. They are not specifically restricted to terrestrial environments.
Answer:
The pancreas is not part of the respiratory system
There would be a increase of Sitka spruce and a slight decrease of Martens.
