The correct option is B.
Erosion refers to the gradual removal and destruction of the earth surface by agents such as water and wind. Water erosion, especially fast moving water is a greater force of erosion than wind erosion because it has greater energy and therefore can cause more damages.
Answer: a. action potential frequency is high enough that no relaxation of muscle fibers occurs.
Explanation:
A tetanic contraction occurs due to repeated stimuli at short intervals. In this situation, the muscle fiber does nor relax and contracts again. It is a process of sustained contraction of muscles, which evoke when the motor nerve innervates a skeletal muscle and emits the action potential at high rate. The muscles become hyperactive in this condition.

Normally a granite, when metamorphosed, would first form a schist, and then a gneiss would be the higher stage of metamorphism. Presumably in this case, the pressure and temperature conditions were high enough to skip the schist step.
Increased carbon dioxide levels
This is because the plant takes in Carbon Dioxide to use it's carbons to help make energy. So if there is more carbon dioxide, there is more photosynthesis going on in the plant since carbon is also in the sugar the plant uses.
