- How does investigating the homeostasis changes during exercise illustrate homeostatic feedback mechanisms in three ways? Please put emphasis on homeostasis changes during exerciseConsider 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.Make and keep a list of the general principles of physiology. See if you can explain what is meant by each principle. To really see how well you’ve learned physiology at the end of your course, remember to return to the list you’ve made and try this exercise again at that time.
- 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.If the blood temperature falls too low, this is also sensed by the brain and signals are sent to the cutaneous arteries (those supplying the skin) to constrict them. Warm blood is then retained deeper in the body and less heat is lost from the surface. If this is inadequate, the brain activates shivering. Each muscle tremor in shivering releases heat energy and helps warm the body back toward its 98.6 degrees set point. • This is an example of a. a negative feedback loop b. a positive feedback loopCreate a transition period for the sport volleyball A Transition Period is the first thing you should think about when considering an extended period of training. Dividing a longer training period into phases is called periodization. Each period has a purpose. And the purpose of the Transition Period is to prepare you for the harder training ahead.
- Think of possible explanations behind the changes in the PR and BP as the subject exerted physical activity. Translate this explanation into a concept map.A behavioral physiologist is studying the homeostatic control of blood pH. In a trial, a lizard runs on a treadmill for a set amount of time and the blood pH is measured. The blood pH drops as carbon dioxide is released into the bloodstream. Which component of the homeostatic feedback system is responsible for determining if the blood pH is far enough from normal that a response is necessary? Sensor Effector Assimilator IntegratorThe benefits of increased daily physical exercise include all of the following, EXCEPT: Question 14 options: providing a distraction to limit over-eating improving fitness levels and quality of life reducing insulin resistance in effector tissues burning an abundance of calories
- Describe what is meant by a trade-off in physiologicalfunctions, and give an example.Turkeys in captivity fed on a grain diet (type of grain unspecified) begin to show abnormal walking and postural behaviors such as staggering, and paralysis of neck and other appendages.
