The answer is <span>B. contains enzymes that begin the breakdown of proteins.
Saliva is watery substance secreted by salivatory glands. <em>It cleanses the mouth</em> and maintenance oral hygiene. <em>It moistens the food</em>, so the created food bolus could easier pass into the esophagus. It also <em>carries food chemicals to taste receptors</em> so they can be tested. It contains enzymes involved in the food digestions. Some of them are amylase, which begins the breakdown of the starch, and lipase, which begins the breakdown of triglycerides. <u>There are no enzymes in the saliva that break down proteins</u>.</span>

Greenhouse gases deplete the ozone layer thereby causing global warming as a result often increase in the intensity of Sun rays reaching the earth.
Example of greenhouse gases include chlorofluorocarbon, nitrogen, water vapor etc
It is an organic substance.
Cellular respiration:
Cellular respiration is the process by which cell break down glucose with oxygen to store the energy as adenine triphosphate or ATP. Energy from ATP is used to help the cell perform daily functions like growing, dividing and repairing itself. Glucose can either be created through photosynthesis in plant cells or ingested in animal cells.
There are four phages of cellular respiration.
• Glycolysis
• Transition stage
• Citric acid cycle
• Electron transport chain
