Using the appropriate osmotic terms (hypertonic, hypotonic, or isotonic) describe what would happen to each organism in the following settings: A single-celled freshwater protist is placed into a beaker of salt water. A salt-water snail is mistakenly put into a freshwater tank. A head of lettuce is placed soaked in a sink of salt water. A carrot is soaked a sink of distilled, pure water.

If an animal cell was placed in a hypertonic solution, which answers predict what would NOT happen? Osmosis will cause the cell to lose water The cell will expand and possibly die due to the gain of salt by diffusion. The cell will shrivel and possibly die due The cell will not change The cell will shrivel and possibly die due to loss of salt by diffusion. The cell will develop cancer The cell will expand and possibly die due to the gain of water by osmosis.
In which situation would passive transport not use a transport protein for entry into a cell? water flowing into a heypertonic environment an ion flowing into a nerve cell to create an electrical potential glucose being absorbed from the blood oxygen moving into a cell after oxygen deprivation
