Explanation:
Answer:
peristalsis.
Explanation:
When the food enters the esophagus, it is in the form of a bolus. During this esophageal stage of swallowing, there are rhythmic contractions and relaxation of the circular and longitudinal layers of the muscularis of the GI tract. It is called peristalsis. This pushes the bolus downwards. Peristalsis in the esophagus is controlled by the medulla oblongata.
As the food enters the stomach, waves of peristalsis pass over the stomach every 15 to 25 seconds. The peristaltic waves in the stomach start at its body and become more intense as they reach the antrum. It moves gastric contents from the body of the stomach down into the antrum, a process known as propulsion.
It would substantially increase as they are responsible for 1/3 of the earths Oxygen and without them "eating" up the CO2 there would be an increase of it in our Atmosphere and a decrease in Oxygen <span />
A chemical solution that becomes warm is an exothermic solution. An exothermic solution is when the solution heats up the air around it, while an endothermic solution would be a solution that cools down the air around it.
Adaptations are like mini evolutions that occur in 1 generation , the plant or animals body changes based on the environment around it. Sometimes when and organism evolves it's because of natural selection, which basically means that the organism with the best trait will survive
