Explain two reasons why a woman with low levels of LH would not be able to
become pregnant. - (answers)(1) LH acts on the ovary to cause ovulation to occur.
(2) LH causes progesterone release to facilitate potential fertilization of the egg
and pregnancy. Progesterone is a key hormone for the maintenance of
pregnancy.
Would you expect a female to have testosterone in their bloodstream? Explain
why or why not. - (answers)(1) Yes. Both male and female bodies produce "all"
the sex hormones. However, the ratios are different. (2) The adrenal glands are
largely responsible for producing this "opposite" hormone that the ovaries would
not.
Label the endocrine glands (A-D) A: ______________ B: ______________ C:
______________ D: ______________ - (answers)A: Thyroid gland B: Adrenal
gland C: Kidney D: Pancreas
3. Label the endocrine glands (A-C) - (answers)A: Pineal gland B: Hypothalamus C:
Pituitary gland
Explain the concept of negative feedback and how it helps to maintain
homeostasis. - (answers)1- The effect or increased level of the hormone acts to
shut down the con!nued release of the hormone. 2- The brain is constantly
monitoring hormone levels to keep levels within a certain range or set-point
(homeostasis). Nega!ve feedback is a way of "turning off" hormone produc!on
when the desired level is achieved

4. Explain the concept of positive feedback. Give an example of a hormone that
works through positive feedback. - (answers)1- Positive feedback is the action of a
hormone increasing the production of that hormone. (This is the opposite of
negative feedback). 2- One example is the action of oxytocin causing the uterus to
contract during labor. Oxytocin enhances the effect of the uterus contractions,
causing more oxytocin to be released. The positive feedback loop is stopped once
the baby is born and the uterus no longer needs to contract, stopping the
production of oxytocin.

5. This type of hormone is derived from proteins:
