Question 3

Suppose that you want to plot metabolic data for animals ranging in weight from 2 g to 10,000,000 g. A log‒log plot would be useful because

Accepted Answer

A) data > 1,000,000 g or < 1 g cannot be plotted on other kinds of graphs. B) a log‒log plot transforms an allometric equation into a curve. C) a log‒log plot puts all animals (e.g., birds and frogs) on the same trend line. D) with a log‒log plot, a wide range of body weights can easily be plotted on the same graph. A) data > 1,000,000 g or < 1 g cannot be plotted on other kinds of graphs. B) a log‒log plot transforms an allometric equation into a curve. C) a log‒log plot puts all animals (e.g., birds and frogs) on the same trend line. D) with a log‒log plot, a wide range of body weights can easily be plotted on the same graph.

Question 4

Accepted Answer

A)  Pygmy mouse 
B)  Wood rat 
C)  Gray squirrel 
D)  Desert cottontail 
A)  Pygmy mouse 
B)  Wood rat 
C)  Gray squirrel 
D)  Desert cottontail

Question 5

Your partner in your new aquaculture business tells you to feed your salmon for another year because they will be bigger upon selling and that garners more money. What is the potential problem here?

Accepted Answer

A)  Your partner is correct and there is no problem because fish keep growing if you feed them. 
B)  Your partner is incorrect; fish stop growing when in captivity for too long. 
C)  Your partner is likely incorrect; while the fish may grow over the next year, it may much slower such that the cost to feed them overtakes the profit. 
D)  Your partner is correct; the longer you feed fish, the more absorbed energy they put into growth. 
A)  Your partner is correct and there is no problem because fish keep growing if you feed them.
