Question
Aerobic scope can be understood as an animal's capacity to increase its metabolic rate above maintenance levels so that they can perform physically demanding tasks. The following statements are true. Please choose all applicable options. A penalty is applied for incorrect selections.Question 5Answera.Salmon performance is highly dependent on and sensitive to temperature changes.b.All salmon stocks have a similar trend that relates temperature to their percentage of aerobic scope.c.All salmon stocks have the same percentage of aerobic scope at any given temperature.d.As temperature increases, various salmon stocks have higher percentage of aerobic scope available to complete cardiovascular demands.e.As temperature increases, various salmon stocks have lower percentage of aerobic scope available to complete cardiovascular demands.
Solution
The correct answers would be:
a. Salmon performance is highly dependent on and sensitive to temperature changes. This is true because salmon, like many other fish species, are ectothermic animals, meaning their body temperature and metabolic processes are influenced by the temperature of their environment.
e. As temperature increases, various salmon stocks have lower percentage of aerobic scope available to complete cardiovascular demands. This is also true. As the temperature increases, the metabolic rate of salmon increases, which can lead to a decrease in the aerobic scope available for other activities. This is because a higher metabolic rate requires more oxygen, leaving less available for other processes.
The other statements are not necessarily true for all salmon stocks, as there can be variations between different stocks and species.
