Question

If the surface area of a cell that is shaped like a cube increases 100 times, its volume increases about (1 point)
5 times.
10 times.
100 times.
1000 times.
2. Compared to small cells, large cells have more trouble (1 point)
dividing.
producing daughter cells.
storing needed materials and waste products.
moving needed materials in and waste products out.

Answer 1

1. Because of the cube-square law, since the square root is 10, 10 cubed is 1000.
1000.
2. moving needed materials in and waste products out.

Answer 2

1. If the surface area of a cell that is shaped like a cube increases 100 times, its volume increases about (1 point)
(0 pts) 5 times.
(0 pts) 10 times.
(0 pts) 100 times.
(1 pt) 1000 times.
1 /1 point
2. Compared to small cells, large cells have more trouble (1 point)
(0 pts) dividing.
(0 pts) producing daughter cells.

(0 pts) storing needed materials and waste products.
(1 pt) moving needed materials in and waste products out.

1 /1 point
3. If a bacterial cell undergoing binary fission failed to replicate its DNA before the division process occurred, what might result? (1 point)
(0 pts) Each daughter cell would continue on with one-half of the parent cell’s genes.

(0 pts) One daughter cell would receive no DNA but would continue to survive because it acquired all other cell components.
(1 pt) At least one cell would die because it would not have a complete copy of every gene.

(0 pts) The cell would switch to a sexual mode of reproduction.
1 /1 point
4. An advantage of sexual reproduction over asexual reproduction is that sexual reproduction (1 point)
(0 pts) takes less time.
(0 pts) requires more time.
(1 pt) provides genetic diversity.
(0 pts) produces identical offspring.
1/1 point
