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.

The terms below relate to the movement of materials and membranes. Answer the following questions by selecting the correct term.

This graph shows the results of an experiment performed using frog eggs, whose membranes are nearly impermeable to water. A scientist injected some frog eggs with messenger RNA that coded for the production of membrane channel proteins called aquaporins. Control eggs were left untreated, so they did not produce aquaporins. Both groups of frog eggs were placed in a hypotonic solution and the volume of the eggs in each group was measured over a 5-minute period. The frog eggs with aquaporins increased in volume until finally rupturing, while the control eggs' volumes remained more constant. Using the graph and your knowledge of aquaporin channel proteins, which statements do you think are true? Select all that apply. relative volume 1.5 1.4 1.3 1.2 1.1 1.0 frog eggs with aquaporin 1 control eggs 2 x (rupture) 3 time (min) 4 -5

Distilled water is to the relative ionic concentration inside of the cell. hypotonic O isotonic O hypertonic
