The hypothesis is that since the basal metabolic rate of birds and
mammals differ from one another based on their mass then the
length of mammals and birds will also influence the change in
their basal metabolic rate.
Consider Figure 49.3 in the textbook. 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.Salmon performance is highly dependent on and sensitive to temperature changes.
b.All salmon stocks have the same percentage of aerobic scope at any given temperature.
c.All salmon stocks have a similar trend that relates temperature to their percentage of aerobic scope.
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.
When the body temperature of ghost crabs is raised from 15°C to 24°C, resting metabolic
rate and
both increase, but the increase in
is much greater than the increase
in resting metabolic rate. Given this information, what would be the likely result if ghost
crabs in nature experienced conditions that raised their typical body temperature from 15°C
to 24°C?
Select one:
a.
Aerobic scope and capacity for aerobic exercise would decrease.
b.
Aerobic scope would decrease and capacity for aerobic exercise would increase.
С.
Aerobic scope and capacity for aerobic exercise would increase.
d.
Aerobic scope would increase and capacity for aerobic exercise would decrease.

- When the environmental temperature is higher than its body temperature, a toucan (a bird with a very large beak) will increase heat loss by... A. Increasing blood flow to the beak to shed heat by radiation and convection B. Moving to a breezy location to take advantage of convective heat loss C. Gular fluttering D. Lowering heat generated via brown adipose tissue E. All of the abovearrow_forwardHeat exchange with the environment depends on the surface area-to-volume ratio of the body. Assuming that the body shape of an animal is at least somewhat spherical, a considerable decrease in body size would the surface area-to-volume ratio, and the ability to exchange heat with the environment would A. increase; increase B. increase; stay about the same C. increase; decrease D. decrease; increase E. decrease; stay about the samearrow_forwardThis is for Animal Physiology.

- The hormone insulin enhances the transport of glucose (sugar) from the blood into most body cells. Its secretion is controlled by a negative-feedback system between the concentration of glucose in the blood and the insulin-secreting cells. Therefore, which of the following statements is correct? A decrease in blood glucose concentration stimulates insulin secretion, which in turn further towers blood glucose concentration. An increase in blood glucose concentration stimulates insulin secretion, which in turn lowers blood glucose concentration. A decrease in blood glucose concentration stimulates insulin secretion, which in turn increases blood glucose concentration. An increase in blood glucose concentration stimulates insulin secretion, which in turn further increases blood glucose concentration. None of the preceding is correct.arrow_forwardAn athlete participates in aerobic exercise three times a week. One of the changes is an increased ability to deliver oxygen to her skeletal muscles. Over time she notices that she can continue the exercise with greater intensity and duration. The reason for this change is that there is a(n) a. greater response from phosphate transfer. b. greater production of ATP from glycolysis and less from aerobic cellular respiration. c. greater production of ATP from aerobic cellular respiration. d. increased production of lactate.arrow_forwardThe regulation of the blood glucose level represents an important feedback loop in the hu- man body. After a meal, the blood glucose level becomes elevated, stimulating beta cells of the pancreas to release insulin into the blood. Excess glucose is then converted to glycogen in the liver, reducing blood glucose levels. Which of the following represents the stimulus in this feedback loop? A conversion of glucose into glycogen B с D elevation of the blood glucose level decrease in the blood glucose level release of insulin by the pancreasarrow_forward
- Thermoregulation is the process by which animals maintain an internal temperature within a tolerable range. Which of the following statement is NOT TRUE about Thermoregulation ? Lütfen birini seçin: O a. Endothermic animals generate heat by metabolism O b. Ectothermic animals gain heat from external sources O c. In general, ectotherms tolerate greater variation in internal temperature, while endotherms are active at a greater range of external temperatures O d. Ectothermy is more energetically expensive than endothermyarrow_forwardAthletes often use whey products to prepare for competition because whey proteins: Group of answer choices are mild stimulants that produce alertness and reduce reaction time provide all the essential amino acids needed to build new muscle tissue elevate testosterone and estrogen in the blood of male and female athletes, respectively produce rapid weight loss by burning excess body fat and sparing glycogen produce free radicals that promote many of the body's beneficial responses to exercisearrow_forwardAdult humans synthesize large amounts of ATP in the course of a day, but their body weights do not change significantly. In the same time period, the structures and compositions of their bodies also do not change appreciably. Explain this apparent contradiction.arrow_forward
