4. Look at the pictures below (chromatin has been
stained red). What phase of mitosis is being shown
in picture B? Explain how you know.
A

C
D
A = anaphase (pulled apart); B = Metaphase
(chromosomes lined up in middle); C = prophase; D =
telophase (two nuclei)

5. What is the surface area to volume ratio of a
cube with 5 cm sides?
SA = 5x5x6 = 150 cm2
V = 5x5x5 = 125 cm3
SA:V = 6:5

help the timing of the cycle?
You must answer in complete
sentences!
9. How do the internal and external regulators
help the timing of the cycle?
Internal – checkpoint inside the cell to regulate
when the cell is ready to advance to the next
step of the cell cycle
External – speed up or slow down the cell cycle

• Cancer cells can not regulate the cell cycle
and divide uncontrollably.

11. Calculate the percent absorption of the cube
below.
SHOW YOUR WORK! Don’t forget units!
11. Calculate the percent absorption of the cube
below.
Total volume = 2x2x2 = 8 cm3
Uncolored volume = 1x1x1 = 1 cm3; colored = 7 cm3
Percent absorption = 7/8 = 87.5%
12. Draw the circular cell cycle figure (with phase
names) from memory. Then check your figure
against the one on page 245 in your textbook.
