Wendy has been doing some undergraduate research in Professor Thomas's biology lab. While riding her bike home late one evening,
she was startled by a careless driver who ran a stop sign just as she was proceeding through the intersection. One of the hormones released into her system was cortisol. Which of the following is true regarding the function of cortisol during the stress response? A. It increases the heart rate.
B. It decreases the appetite.
C. It mobilizes nutrients to be used for energy.
D. It relieves pain.
The hypothalamus ,pituitary and the adrenal glands are responsible fot controlling hormone secretion in the body.
Cortisol is one of the hormones that is released in the body. It is a steroid hormone produced in the adrenal glands at the Zona fasciculata of the adrenal gland cortex.
Its functions include help in regulating blood sugar levels and regulate metabolism among others.
For instance, during the stress response or danger. It increases the body's metabolism of glucose to produce energy.
More energy is needed to carry out the metabolic rate of a person ( the minimum amount of energy required to carry out all of the reactions needed to keep a person alive).
rusting of iron is a chemical change because it is two substances reacting together to make a new substance. When iron rusts, iron molecules react with oxygen molecules to make a compound called iron oxide. Rusting would only be a physical change if iron molecules remained pure iron throughout the process.
