Some students used vinegar to dissolve a way the shells of three eggs and used these eggs as models of human red blood cells. The students observed the changes in the eggs when they were placed in different solutions. Which statement best describes the role of the cell membrane in this model?
The cell membrane is an impermeable barrier that prevents water from entering the cell.
The cell membrane allows solutions to enter the cell, which causes the cell to shrink.
The cell membrane allows water to enter and leave the cell.
The cell membrane removes solutes from the environment.
Viruses are considered nonliving because they need a host to reproduce.
True
False

Plant cells are able to produce their own food. This process happens in which structure?
cell wall
chloroplast
mitochondrion
vacuole
These diagrams show a variety of cells from the same organism. How can cells from the same organism have such different shapes and functions?
As each cell differentiates, the DNA changes so that each type of cell has different DNA once it reaches maturity.
Mutations in the cells' nuclei lead to new combinations of DNA, resulting in different shapes and functions in the different types of cells.
During differentiation, different parts of the DNA in each type of cell are activated, resulting in the different structure and function of the cells.
During differentiation, different types of cells produce proteins which destroy the nonactive DNA, leading to cell specialization.
Which statement best explains how sweating during exercise maintains homeostasis?
It regulates mineral concentrations in cells.
It regulates body temperature.
It maintains water balance.
It maintains sugar balance in cells.
A person with swollen gums rinses his mouth with warm salt water, and the swelling decreases. Which has occurred?
The swollen gums have absorbed the saltwater solution
The saltwater solution lowers the temperature in the gums
The salt in the solution has moved against the concentration gradient
The water in the gums has moved from a high to a low concentration of water
If energy is needed to move materials into or out of a cell, what is most likely occurring?
