At the end of winter, water containing very high concentrations of road salt used to deice roadways runs off and some of it enters a very small freshwater pond that contains many aquatic organisms including paramecium. What do you suppose will happen to the paramecium? a
The paramecium's environment will become hypertonic causing paramecium cells to burst

b
The paramecium's environment will become hypotonic causing paramecium cells to burst

c
The paramecium's environment will become hypotonic causing paramecium cells to shrivel

d
The paramecium's environment will become hypertonic causing paramecium cells to shrivel

D

Explanation:

The water molecules in the cell will want to move out of the cell into the pond in attempt to lower the salt concentration which will cause the cells to shrivel up with the loss of water. This is also called becoming hypertonic.

the correct answer is: b. pantala flavescens, because these organisms would have a high level of genetic variation due to sexual reproduction.  

because involves two organisms (parents) whose genetic material combines, sexual reproduction leads to genetic variation in new generations of offspring. the offspring is an unique organism, with new genome, more protected with the higher ability to adapted. this process is fundamental to evolution.
