Which best describes when the body is working on counteracting an effect?

when hormone levels in the body are all equal

during a negative feedback loop

during a positive feedback loop

when the hypothalamus is signaling the pituitary gland

The answer is a negative feedback loop. Negative feedback is used to counteract an effect and achieve back a homeostatic balance. An example of a negative feedback loop is in thermoregulation. When temperatures are too high, the hypothalamus induces body responses such as vasodilation and sweating that enable the loss of excess heat.
