When molecules of one substance are spread evenly throughout another substance to become balanced.

• energy

• equilibrium

• osmosis

• channel protein

Which of the following is true?

• The solution is hypertonic, water will exit the cell, causing it to shrink.

• The solution is hypotonic, water will exit the cell, causing it to shrink.

• The solution is hypertonic, water will enter the cell, causing it to swell.

• The solution is hypotonic and water will enter the cell, causing it to swell.

Isaiah is a student in biology. He was was given the responsibility of caring for paramecium (freshwater protists). He accidentally put them in a saltwater solution. What happened to the poor paramecium?

• The paramecium lost water from their bodies and shriveled.

• The paramecium lost water from their bodies and burst.

• The paramecium survived and reproduced..

• The paramecium enjoy both saltwater and freshwater equally.
