SHORT ANSWER
23. ANS:
A—G1 phase, cell growth; B—S phase, DNA replication; C—G2 phase, preparation for mitosis; D—M phase,
cell division (mitosis and cytokinesis).
OTHER
24. ANS:
It shows various stages of mitosis in an animal cell. We know this is an animal cell because of the presence of
centrioles and the shape of the cells.
25. ANS:
Four
26. ANS:
X is the centriole; Y is a spindle fiber.
27. ANS:
D, A, C, B
28. ANS:
The next step would be cytokinesis. It would show two daughter cells forming.
29. ANS:
The student is varying the size of the cubes and testing how far a solution can diffuse into each cube; thus, she
is probably testing the effect of size on the diffusion of materials into each cube. The cubes probably represent
cells.
30. ANS:
Surface area = length  width  the number of sides = 2  2  6 = 24 cm2. Volume = length  width  height
= 2  2  2 = 8 cm3. Ratio of surface area to volume = 24/8 = 3.
31. ANS:
Students should conclude that the largest cube has the smallest ratio of surface area to volume, and the
smallest cube has the largest ratio of surface area to volume.
32. ANS:
The vinegar will turn the pink parts of the cube clear. Thus, the student can cut each cube in half and measure
the amount of each cube that has changed from pink to clear.
33. ANS:
The rate of diffusion should be constant across all three cubes. The vinegar will diffuse to a greater extent into
the smaller cube than into the larger cubes because the ratio of surface area to volume is larger for the smaller
cubes.
