Answer:
A prostaglandins
Explanation:
Fever is the abnormal body temperature that is caused by pyrogens.Pyrogens are the chemicals produced by pathogen. Fever is protective mechanism of body to fight against pathogens. It is actually the immune response that spread to whole body with elevated temperataure. The elevated temperature helps to deal with pathogen more efficiently.
The interleukins released be immune cells in response pyrogen ultimately lead to release of prostaglandin E2. Prostaglandin E2 reset the hypothalamus thermoregulation. The hypothalamus feels the body temperature is cool although how high is the body temperature.
The answer is A because the electromagnetic spectrum is the thing that makes it visible
Answer:
The magnitude of the net force acting on an object is equal to the mass of the object multiplied by the acceleration of the object as shown in the formula below. If the net force acting on an object is zero, then the object is not accelerating and is in a state that we call equilibrium.
Explanation:
This equation is the sum of n forces acting on an object. The magnitude of the net force acting on an object is equal to the mass of the object multiplied by the acceleration of the object, as shown in this formula.
