This process requires large volumes of water to pass through absorption surfaces to get enough oxygen into their bodies using their mouths and gills. These body parts work like a pump to keep water moving over the gas absorption surfaces of the gills.
Answer:
As the population increases, the food supply, or the supply of another necessary resource, may decrease
Explanation:
The correct answer is D. The theory of natural selection provided a better explanation of the processes that were being observed by the scientists.They observed that the related species birds found on one island were slightly different from that of the other, and certain portions earth, have the species, which were not found anywhere else.
I believe the correct response would be B. Since of evolution were to occur, the possibility of the geographically isolated snakes to reproduce would be 0. Since the gene pool or the collection of all the genes in the population were to change and as a result of future reproductions of the 2 populations over time, transmission of specific genes that code for traits were to be specific for that population, ultimately not allowing them to reproduce.
