An acid rain is a type of rain or precipitation that has a high level of hydrogen ions resulting in low pH. It can prevent growth of seedlings because it hinders the cell division of plants. Since animals consume plants, they can establish new dietary habits or migrate to areas that have a healthier environment.
Answer: Rift valleys form when plates move <u>apart</u>. This type of plate boundary is called <u>divergent</u>
Explanation:
A diverging plate boundary is the most likely location for a rift valley. Because rift valleys form when two tectonic plates move apart from each other which is similar to the action and definition of a diverging plate boundry
Answer:
D. The presence of aquaporins (proteins that form water channels in the membrane) should speed up the process of osmosis.
Explanation:
Water moves in the cells through osmosis which means water moves from its higher concentration to lower concentration. In many animals and plants, water channels are also present which is called aquaporins which allow the water to move through it in and out of cell more quickly.
The rate of diffusion by channel proteins is higher than simple diffusion therefore the aquaporins speed up the process of osmosis. No ATP is required to transport the water through aquaporin channel proteins.

Explanation:
cell reproduction is the process by which cells divide to form new cells. each time a cell divides it makes a copy of all its chromosomes, which are tightly coiled strands of DNA, the genetic material that holds the instructions for all life, and sends an identical copy to the new cell that is created.
