Hello! I am almost certain the answer is "C". Mark me brainliest if you get a chance :)
The activation energy of a chemical reaction is closely related to its rate. Specifically, the higher the activation energy, the slower the chemical reaction will be. This is because molecules can only complete the reaction once they have reached the top of the activation energy barrier.
The ocean-floor feature is indicated by the arrow in the image and it is a seamount. A seamount is a submarine mountain and it is found on oceanic crust near mid-ocean. It is formed <span>by volcanic activity and the longest seamount would be the New England Seamounts.</span>
<span> Gastrin is produced by
G cells in the pylorus and the duodenum. Gastrin stimulates the secretion of
both parietal and chief cells. It causes the gastric glands to increase their
secretory activity and stimulates gastric motility. Saliva, food, and gastric
juice are mixed together in the stomach to form chyme. The stomach serves as a
reservoir for food before release into small intestine. Gastric juice is
secreted into the lumen of the stomach. Gastrin is secreted into the
bloodstream.</span>
