Textbook Question
Chapter 1, Problem 15RQ
Although dehydration is one of the most serious physiological obstacles that land animals must overcome, there are others. Think of as many as you can, and think of various strategies that different terrestrial animals have to overcome these obstacles. (Hint: Think of humans, insects, and amphibians; also think of as many different terrestrial habitats as you can.)

Some athletes have drink beet juice (yes, juice from beets) to improve their endurance performance. Beet juice is known to contain high levels of a molecule called nitric oxide (NO) which may improve
blood flow from lungs to working muscles by causing the dilation (widening) of blood vessels. Select the pair below that includes the most related subdiscipline and physiological system.
O lungs / muscles
O motor behavior / endocrine
O sports nutrition / cardiovascular
O biomechanics / cardiovascular
O kinesiology/thermoregulation

- Predict what would happen to the metabolic rate of the mouse if you increased the temperature. Predict what would happen to the metabolic rate of the mouse if you decreased the temperature (You can make this prediction with text or with lines on your graph). Support your prediction with evidence about endotherms and ectotherms. (Hint: Think about what happens to your body when you get hot or cold.)arrow_forwardThe respiratory system is capable of absorbing oxygen and excreting carbon dioxide. The digestive system absorbs nutrients from the diet and excrete indigestible material including wastes. Likewise, the urinary system is capable of absorbing and excreting water and electrolytes according to the needs of the body. These functions may appear to be distinct and separate from each other, but the systems are so organized that they are interdependent on each other and together contribute to the welfare of the body by keeping it in balance or in a state of homeostasis. Create a concept map that illustrates the physiology of acid base balance that unites the three systems (Respiratory, Digestive and Urinary systems) together.arrow_forwardInterpret your data in Graph 1 (Image of Graph 1 attached); What does your data tell you about the effect of temperature on: a) opercular movements in goldfish? AND b) gas exchange in goldfish? Why can data from the control fish be used as a standard for comparing opercular movements in the experimental fish?arrow_forward
- 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.arrow_forwardRiding a bicycle requires additional energy from leg muscles. Which of the following conditions may result from this activity, and which response helps restore the body to its normal condition? * decreased oxygen can be replaced by digesting an apple. increased carbon dioxide in the blood can be removed by breathing faster. increased sugars in the bloodstream can be diluted by drinking water. increased salt wastes can be removed by the heart.

- Consider an ectotherm and an endotherm of equal body mass. Which of the following would you expect to be true? -both animals require the same amount of energy per unit mass -the ectotherm requires more daily calories from food than the endotherm -the endotherm requires less energy per unit mass but more total energy than the ectotherm -the ectotherm requires less energy per unit mass but more total energy than the endotherm -the ectotherm could survive a longer period without food relative to the endothermarrow_forwardElaborate the four unifying themes of animal physiology and give examples.arrow_forwardConsider 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.arrow_forward

Describe the system, giving the stimulus, the response, and how that maintains function of the system. describe a real or hypothetical condition caused by disruption of this system.arrow_forwardDraw a negative feedback loop for maintaining homeostasis for thermoregulation where your body temperature is above the set point. In your drawing, include the stimulus, sensor, integrator, effector, and the arrows between the components to indicate how they all relate (be sure to indicate what each of these components are in your body, for example, what is your integrator). Further, answer the following two questions. First, what might be different between the response of an endothermic and an ectothermic animal in maintaining homeostasis?
