A student claims, "In order to maintain homeostasis, the body utilizes a
variety of feedback mechanisms." Which of the following is an example
of a positive feedback mechanism that could be used to support this
statement?
O An increase in body temperature causes humans to secrete a watery fluid in
the form of perspiration. As the fluid evaporates from the skin removing the
excess heat, the body stops perspiring.
O O2 levels in the blood increase and CO2 levels decrease. The brain tells the
muscles of the diaphragm to inhale and exhale more rapidly. As O2 and CO2
levels returns to normal, the organism's breathing returns to normal.
During childbirth, the release of the hormone oxytocin stimulates uterine
contractions, which in turn stimulates the release of more oxytocin.
O High levels of glucose cause the partcreas to secrete more insulin. As
glycogen forms from glucose, glucose levels decline and the pancreas stops
secreting insulin.
