Biology Pre-Assessment

Within an organism, muscle cells and nerve cells differ in both structure and function.  How is this possible?

• They use different parts of the DNA

• They contain different chromosomes

• They have different cell walls

• They contain different DNA

The part of the cell that controls what enters and leaves the cell is the __.

• cytoskeleton

• cell membrane    

• Golgi apparatus

• Nucleus

A severely dehydrated person is often given intravenous saline injections. Saline (0.9% salt) has the same electrolyte concentration as human cells.  What would happen if pure water was introduced into the body instead of saline?

• The cells would gain water and swell.

• The cells would lose water and shrivel

• The cells would become impermeable to sodium ions

• The cells would become impermeable to chloride ions
