Answer is A. A population becomes separated by environmental factors into two groups that do not reproduce with one another.

When a population of a species become geographically separated then gene flow between them stops. Over a period of time, the population may become genetically different in response to the natural selection due to different environments. Selection and genetic drift will act differently on these two separated populations. This will results into two separate species. This type of speciation is called allopatric speciation.

What is the idea of Continental Drift?
Tamiku [17]
Geologist Alfred Wegner noticed similar rocks & fossils remains were found on Continents which seemed to fit together. He called saw that it was the result of Continental drift and Pangea. Some evidence of the Drift was Rock evidence- Mountain ranges, Glacial scares, Location of coal deposits, ETC.. 

People couldn't image how the Earth could be millions of years ago. But the 1960's evidence would prove Continental Drift is TRUE and .. the story continues (as all good science!)

Continental drift means that continents move away from each other or separated.

Olenka [21]

Answer:

Remove and lower.

Explanation:

Cells of the excretory tubule remove water by osmosis, from which we can conclude that the solute concentration in these cells must be lower than in the filtrate. The excretory tubule remove excess amount of water from the cell through semi permeable membrane of the cell while on the other hand, the solute concentration in the cell is lower as compared to filtrate so that's why it can't diffuse from the cell by the process of osmosis.
