Explanation:
maintaining a stable environment controlling what enters and exits the cell movement of materials into the cell
Hypothalamus is a part of the brain that links the nervous system to the endocrine system via the pituitary gland. It helps maintain the internal environment constant by regulating major processes in the body such as the heart rate and the body temperature. It is therefore, both a neural and endocrine organ.
C. The sum of all forces on an object in equilibrium is zero. Equilibrium means in a stationary position. Therefore there is no acceleration. And using Newton's second law, we can say that the net or resultant force is 0.
F = ma
=>F = m(0)
=>F= 0
