C. They are pulled toward Earth by the force of gravity (and in Physics you would learn that the deceleration speed of gravity is -9.8m/s/s)

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.
Male animal aggression during mating season. The evolutionary purpose of most species is to repopulate and keep the species alive long enough to become the highest being it can evolve into (We humans have done the best at this so far). So, every male in a species gets aggressive during mating season because the stronger ones are most likely to have healthy offspring. So, when animals fight they are fighting to keep their species alive. If you think about it who wouldn't want to be responsible for the evolutionary breakthrough that kept a species alive over thousands of years? hope this helped.
