3. Limiting development on floodplains is effective in controlling floods because this
keeps costs lower than they are when building structures on flat land
keeps floodwaters within channels
eliminates wide stream meanders
allows floodplains to absorb floodwaters without harm to structures

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.
