Eric If a swimmer has a lung volume of 6 L at sea level (atmospheric pressure), what would the volume of her
lungs be when she is at the bottom of a pool that is 8.0 m deep? Assume that the temperature and
amount of the air in the lungs remain unchanged.

The pharynx is the structure in the body that serves as a pathway of both air and food. how does the body make sure that food does not get into the lungs? the salivary glands secrete enzymes that pull food out of the air pathway. the small intestine pushes the air out of the digestive system. the pancreas breaks down food in the air pathway. the epiglottis closes the air pathway so that food will not enter it.

Is there any species that went extinct in recent years due to natural causes (not caused by human interaction). if so, what caused it?

During the final stage of the cell cycle, cytokinesis allows the cell to finish dividing, creating with copies of dna. can someone fill in the blanks?
