1
According to your data, the largest mouse consumed:
A)less oxygen per minute than the smallest mouse.
B)more oxygen per minute than the smallest mouse.
C)the same amount of oxygen per minute as the smallest mouse.
2
For each mouse you should have a number of values for the amount of oxygen consumed per minute. Looking at general trends, which value was the highest?
A)The first value you recorded for the mouse.
B)The second value you recorded for the mouse.
C)The third value you recorded for the mouse.
D)The fourth value you recorded for the mouse.
3
Why do you think a mouse consumed more oxygen per minute when it was first put into the cage?
A)There was more oxygen available in the presence of soda lime.
B)Low carbon dioxide levels increase metabolic rate.
C)The animal was cold in the chamber.
D)Handling disturbed and stressed the animal.
4
After a few minutes, the rate of oxygen consumption decreased because:
A)the oxygen level decreased over time.
B)the soda lime took up less carbon dioxide.
C)the stress level of the mouse decreased, and it became relaxed.
D)the mouse lost heat and warmed the chamber.
5
According to Rubner's Surface Rule, the surface to volume ratio for a spherical animal with a radius of 3 inches would be:
A)1:9.
B)1:6.
C)1:5.
D)1:3.
6
Look at the final graph. Did the smallest mouse consume:
A)less oxygen/hour/gram than the largest mouse.
B)more oxygen/hour/gram than the largest mouse.
C)the same amount of oxygen/hour/gram as the largest mouse.
7
Do you think a gram of a liver (for example) from smallest mouse has:
A)substantially more cells than a gram of a liver from largest mouse.
B)about the same number of cells as a gram of a liver from largest mouse.
C)substantially fewer cells than a gram of a liver from largest mouse.
8
If a gram of mouse liver (for example) has the same number of cells, then one cell from a small animal will consume:
A)more oxygen per minute than the same cell in a large animal.
B)the same amount of oxygen per minute as the same cell in a large animal.
C)less oxygen per minute than the same cell in a large animal.
9
Assuming that a mouse loses heat across its body surface, if a smaller animal has fewer cells per square inch of surface area, these cells must have:
A)a high metabolic rate to generate enough heat to maintain body temperature.
B)the same metabolic rate.
C)a low metabolic rate to generate enough heat to maintain body temperature.
10
The smallest mouse should have consumed:
A)less oxygen/hour/gram than the largest mouse.
B)the same amount of oxygen/hour/gram as the largest mouse.
C)more oxygen/hour/gram than the largest mouse.
