2. What is the difference between a nucleotide and a nucleic acid? What are the 3
components of a nucleotide?
3. List three important functions of proteins
4. Answer the questions below based on the following diagram of an animal cell placed in a
beaker of solution. In this example, the cell’s membrane is permeable to NaCl and to
water (remember, a 10% NaCl solution means there is also 90% water inside the cell)

Is the solution hypertonic, hypotonic, or isotonic? (circle one)
Is the inside of the cell hypertonic, hypotonic, or isotonic? (circle one)
Will water move into the cell or out of the cell? _____________
Will NaCl move into the cell or out of the cell?______________
Water and NaCl will continue to move across the membrane until the solutions
inside the cell and in the beaker become: hypertonic, hypotonic, or isotonic?
