Most animal cells are bathed in an isotonic fluid, such as blood, which protects them from bursting. how does an isotonic solution protect a cell from bursting?

a. it is a solution that has no solutes, making it an empty fluid.

b. the concentration of solutes is equal on both sides of the cell, so the water doesn't rush in.

c. it is a solution with a concentration of solutes higher on one side of the cell than the other.

Ry was studying two populations of the same species of lizards. one population lived on an island and the other lived on the mainland. both populations were affected by a hurricane that hit the island and the mainland with equal force. a year later, henry was testing the gene frequency and saw a decrease in genetic variation in the island species, but not in the mainland species. which best describes a conclusion he might have reached? gene flow greatly affects small populations, but large populations can recover. genetic drift greatly affects small populations, but large populations can recover. gene flow greatly affects large populations, but small populations can recover. genetic drift greatly affects large populations, but small populations can recover.

Which of these is true for bacteria because they are prokaryotic cells? a. they can engulf body cells in order to make memory cells. b. they must invade viruses in order to reproduce. c. they are much larger than eukaryotic body cells. d. they can reproduce on their own outside of other cells.
