Answer:
A. What is the effect of pesticides on the environment
Explanation: I just took the test
Allopatric<span> speciation occurs when new species arise as a result of geographic isolation from the ancestral species. It involves an extrinsic barrier to gene exchange and can occur by a number of means including subdivision or peripheral division.</span>
I'm a little confused by this question. Hypertonic just means that something has more of something than another thing. For example, if you place a cell in a solution, and 2% of the cell is made out of something while the solution is made out of 40% of the same thing, the solution would be hypertonic to the cell. Sorry if that explanation doesn't make sense, I tried my best lol.
Although I'd assume the answer is passive transport as anything that is hypertonic to something else will diffuse down its gradient in an attempt to reach a balance.
D is the answer. Mutations can cause MANY problems.
