A fever is an increase in body temperature above normal range. A fever causes metabolic changes that push the person's body temperature even higher. If body temperature rises above 45oc death occur because cellular proteins change shape and metabolism stops. Is a fever of positive or negative feedback system? Explain

Positive feedback loops are the opposite of negative feedback loops. In a positive feedback loop, any change in the original variable triggers mechanisms that actually push the variable further in the direction of the change. Imagine that body temperature was regulated in this way. Briefly explain what would happen.
in few sentence explain why is the importance of warming up? What physiological changes occur?
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
What should happen to Body temperature ,Hydration Levels ,Blood glucose levels and Oxygen levels 30 minutes after completion of marathon? Is this an example of negative or positive feedback? Explain reasons
When you step outside in the cold, your body temperature decreases; which causes shivering or contractions of your muscles. In this example, the shivering or contracting of the muscles, is what part of the feedback loop?
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.
Which of these is a result of homeostasis?a. Muscular tissue is specialized to contract.b. Normal body temperature is always about 37°C.c. There are more red blood cells than white blood cells.d. Receptors in the eyes detect light.
In the negative feedback system for regulation of body temperature. Identify the following. 1. Stimulus 2. Receptor 3. Control Center 4. Effector 5. Response
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.
Explain why the human body utilizes negative feedback loops verses positive feedbackloops to maintain homeostasis.
which of the following statements are true about homeostasis? Select all that apply. a. The selective permeability of the cell membrane allows for thermoregulation. b. Homeostasis is an organism‘s way of maintaining constant and balanced internal processes. c. Ectotherms rely on environmental heat to maintain homeostasis. d. Homeostasis works by a system of positive feedback.
