Final - Fish Metabolism

Question 1

In the goldfish metabolism lab, there was a probe attached to the chamber.

Select one:

a. The probe was crucial in maintaining constant dissolved oxygen levels.
b. The probe was measuring the dissolved carbon dioxide concentration in the water independent of the mass of the goldfish.
c. The probe was measuring the dissolved oxygen concentration in the water.
d. The probe was measuring the quantity of carbon dioxide emitted from the fish.
e. The probe was measuring metabolic rate of the goldfish independent of the mass of the goldfish.

Answer 1

c. The probe was measuring the dissolved oxygen concentration in the water.

Question 2

What is the relationship between mass-specific metabolism and body size?

Select one:

a. None of these
b. As body size increases, M-S metabolism decreases
c. As body size decreases, M-S metabolism decreases
d. AS body size increases, M-S metabolism stays the same
e. As body size decreases, M-S metabolism stays the same.

Answer 2

b. As body size increases, M-S metabolism decreases

Question 3

An ectotherm is:

Select one:

a. None of these
b. An animal that is capable of generating its own body heat therefore its body temperature stays constant over a wide range of ambient temperature.
c. An animal that obtains its body heat from the environment therefore its body temperature varies with outside temperature
d. All of these
e. An animal that continually radiates heat to its environment

Answer 3

c. An animal that obtains its body heat from the environment therefore its body temperature varies with outside temperature

Question 4

Why is it easier to use poikilothermic goldfish in the “Metabolism in Goldfish” lab, instead of homeothermic humans?
Choose one answer.
a. The metabolic rate of a human is much faster, making it difficult to determine
b. It is easier to detect dissolved oxygen than atmospheric oxygen
c. It is too expensive to test the metabolic rates of homeothermic organisms
d. Goldfish tend to be smaller than humans, thus it is easier to manipulate their metabolic rates
e. Goldfish’s metabolic rates have a direct relationship with environmental temperature making their metabolic rates easier to manipulates

Answer 4

e. Goldfish’s metabolic rates have a direct relationship with environmental temperature making their metabolic rates easier to manipulates e. Goldfish’s metabolic rates have a direct relationship with environmental temperature making their metabolic rates easier to manipulate

Question 5

Loggerlite detects the amount of dissolved oxygen in the chamber. For each trial, the datapoints are plotted and a curve is generated. The greater the value of the slope,
Choose one answer:
a. the lower the rate of carbon dioxide consumption
b. none of the above
c. the greater the rate of carbon dioxide production
d. the lower the rate of oxygen consumption
e. the greater the rate of oxygen consumption

Answer 5

e. the greater the rate of oxygen consumption
