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.
I think is false if i'm not mistaken only cause the mantle and the crust is larger then the outer and inner core
Considering the definition of volume, the volume of a cube with a side length of 3 centimeters is 3 cm³.
<h3>Volume</h3>
Volume is a measure of the space occupied by an object in three-dimensional space.
In other words, volume of a geometric figure is defined as the amount of space occupied by the object or figure in three-dimensional space. Volume is measured in cubic units.
The volume of a cube is equal to the measure of its side to the cube. That is to say:
Volume = side x side x side = side³
<h3>This case</h3>
In this case, you have a cube with a side length of 3 centimeters. Replacing in the definition of volume:
Volume= 3 centimeters× 3 centimeters× 3 centimeters
Solving:
<u><em>Volume= 3 cm³</em></u>
Finally, the volume of a cube with a side length of 3 centimeters is 3 cm³.
