Some students used vinegar to dissolve away the shells of three eggs and used the eggs as models of human red blood cells. The students observed the changes in the eggs when they were placed in different solutions. (View Image)
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 solutes 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.

a vertebral column
a vertebral column and hair
sharp teeth and retractable claws
the ability to purr
Which of the following equations represents the overall chemical reaction for photosynthesis?
6O2+ 6H2O → C6H12O6+ 6O2
C6H12O6 + 6H2O→ 6O2+ 6O2
6CO2+ 6H2O→ C6H12O6+ 6O2
6O2 + 6H2O→ C6H12O6 + 6CO2
The rate of photosynthesis can be influenced by...

It takes place in the stroma
Autotrophs (producers) can perform photosynthesis because they have -
Mitochondria
Ribosomes
A Nucleus
Chloroplasts
How does most of the water needed by the plant get into its leaves?
