Answer:

the correct answer is E

Explanation:

In the sum of contractions, the action potentials are sent more frequently but not with greater intensity, this is because in the motor plate the neurotransmitters do not cease and continue to bind to their receptors, promoting the stimulation of muscle fiber, once the muscle fiber contracts, before returning to its depolarized or resting moment a new contraction begins, some researchers maintain that these contractions are stronger but that the action potential that stimulates them does not refer to more power.

Type the answer through sentences please and thank you
Nonamiya [84]

In order for plants to make their own food, they must go through a process called photosynthesis. This process occurs in the chloroplasts of a cell. To begin this process, all items needed must go to the cells of a plant. Water and nutrient are absorbed from the soil through the roots. A tube called the xylem carries only water up the stem to the rest of the plant. Gas exchange in the plants occur in the tiny pores of a leaf called the stomata. This is opened and closed by the guard cells. The food produced by this process is called ATP and it is a macromolecule known as a nucleic acid.
