Answer:
c) receptor; control center; effector.
Explanation:
Homeostasis maintains the internal body conditions almost constant. It includes specific cells that sense any deviations of internal or external conditions from the normal range. These cells are called receptors. The sensory information from the receptors is delivered to the control center. The central nervous system mainly serves as a control system wherein sensory information from the receptors is processed. The control center commands muscles and/or glands to perform desired responses to restore the homeostasis. Here, muscles and glands serve as effectors.
For example, thermoreceptors sense the rise of body temperature and the brain (control center) commands sweat glands (effectors) to produce sweat.

Answer:
<em>The amount of energy needed to support the cost of building new tissue and the material that makes up tissue is the cost of proteins and is taken into consideration for growth and repair of tissues</em>
Explanation:
<em>The proteins we ingest as part of our meals per day, are broken down in the guto amino acids. Our bodies can use it for growtn and repair of tissues, as an energy source or as primary materials necessary for the production of other compounds needed by our bodies.</em>
<em>We must include animal protein in our diet, because animal sources contains all of the essential amino acids needed, whereas plant sources of protein do not.</em>
