The pyloric valve control food movement from the stomach into the small intestine.
The best answer is C - to break down food into nutrients.
The digestive system breaks down food into its simplest form that cell are able to utilize for energy. Food is broken down into its monomer units. Proteins are broken down into amino acids, lipids are broken down into fatty acids and glycerol and carbohydrates are broken down into glucose.
Glucose is then absorbed into the blood and transported to every cell in the body. The cells take in glucose and use it as fuel and raw material in the process of cellular respiration. From one molecule of glucose, 36 to 38 molecules of ATP ( the form of energy used by cells) are produced.
The leading cause is garbage and waste from people.

In scientific notation, the value of the speed of light in a vacuum
will be written as 2.995 * 10^8. When this value is represented in the form of
a * 10^b, then, a = 2.995 and b = 8.
The value of the speed of light in a vacuum given above can also be rounded up to approximately 300000000. In this case, the scientific notation will be written as 3 *10^8.
