Riding 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. No answer

During intense exercises and when muscles are working harder, our cells metabolize glucose rapidly resulting to oxygen molecules being quickly consumed. Which of the following becomes the human body's coping mechanism in response to limited oxygen supply? faster breathing and lower blood circulation slower breathing and faster blood circulation faster breathing and faster blood circulation slower breathing and slower blood circulation
If the oxygen level in the blood decreases, the brain sends a message to the lungs/diaphragm to breathe faster, which increases the levels of oxygen in the blood. This describes a negative or positive feedback loop.
Which of the following is an example of negative feedback? A. High blood sugar will increase the viscosity of blood plasma (plasma is concentrated). In response, water is drawn into the plasma from surrounding tissues in order to dilute the plasma B. Breathing rate increases during exercise to provide more oxygen to muscle cells. Heart rate also increase to increase the speed at which the oxygen is delivered. C. During digestion cells in the stomach produce HCl to begin breaking down proteins, the HCl then stimulates the release of pepsin, to continue breaking down proteins. D. In the immune system, antibodies produced by B-cells bind to antigens, which activates other B-cells to produce antibodies of the same kind.
If the oxygen levels increased throughout your body, you would expect to see the following occur to bring levels back to homeostasis Group of answer choices A decrease in sympathetic activity to the smooth muscle of blood vessels An increase in heart rate An increase in stroke volume An increase in parasympathetic activity to the smooth muscle of blood vessels An increase in sympathetic activity to the heart
How is homeostatis maintained by the body system is related to diabetes in respiratory system? (ANSWER IN BULLET SENTENCES!! NOT PARAGRAPH!!)
Jamie has fallen ill. Her body temperature has risen to high levels. Her blood pressure is high and her glucose level is low. In order for her body to return to homeostasis and for Jamie to feel better, the following events are taking place: Select all that apply Dilating blood vessels reduce blood pressure Lowering her body temperature by sweating Raise her body temperature by sweating Apply positive feedback to restore glucose levels in the blood stream by using the hormone glucagon which will raise blood sugar Apply negative feedback to restore glucose levels in the blood stream by using the hormone glucagon which will raise blood sugar Constricting blood vessels to increase blood pressure
Which of the following best describes an example of negative feedback? The body starts shivering to generate heat when you detect you are too warm. The feeling of hunger after you've just had a big meal. The increase in breathing rate when the body detects you are low on oxygen and high on CO2. A decreased heart rate in response aerobic exercise. The body sweating when the temperature gets too cold.
Since humans began playing sports there have probably been people willing to cheat to gain an advantage. One form of cheating utilized by endurance athletes is called blood doping, which relates to our study of cellular respiration. “Blood doping is the misuse of certain techniques and/or substances to increase one’s red blood cell mass, which allows the body to transport more oxygen to muscles and therefore increase stamina and performance.” Definition from https://www.wada-ama.org/en/questions-answers/blood-doping From PED, to shaving points, bribery to drugging opponents (https://www.irishtimes.com/sport/maradona-backs-branco-s-claim-of-drug-laced-bottle-at-italia-90-1.4091470), there seems to be countless ways for athletes for gain an advantage. My question for the class is… What is the worst ethical offense that an athlete can commit? Do you know of any examples where this may have happened?
Which of the following statements regarding skeletal muscle is NOT true? Skeletal muscle is responsible for overall body motility. Skeletal muscle can contract rapidly and can maintain the contraction for long periods of activity .Skeletal muscle can exert tremendous power. Skeletal muscle is called voluntary muscle because it is the only type subject to conscious control.
On Thursdays, you get together with friends to play soccer at the park. One of your friends, Jenny, recently started a high fat, low carbohydrate diet. She commented to you that she feels sluggish and tired when she plays soccer. Based on your knowledge of exercise and fuel sources, explain why she feels this way.
Which of the following statements is True?a. Ectotherms generate most of their body heatmetabolically.b. Ectotherms include birds and mammals.c. Ectotherms experience variable body temperatures.d. Ectotherms are known as “warm-blooded” animals.
Fill in the blank During an infection, the body temperature set point is increased. The hypothalamus communicates to skeletal muscles to shiver and to blood vessels to.......... blood flow to the skin, causing a rise in body temperature
