<span>In short, water and oil don't mix because they are two substances with different types of molecules. The structure of oil's molecules makes it hydrophobic, so it won't mix with water's molecules. Water is a polar molecule, meaning the amount of electrons in the hydrogen and electronegative oxygen is unequal....</span>
The answer is option A "be affected." Every species is prey and a predator. For example a fox eats rabbits and a mountain lion eat's the fox. So if a fox species dies rabbits population would increase (since how they have one less predator to eat them) and mountain lions population would decrease. (since how they lost a food source so they will starve)
Hope this helps!
i think d. is the best answer .
