Explain two reasons why a woman with low levels of LH would not be
able to become pregnant. - ANSWER >>>>>(1) LH acts on the ovary to

female bodies produce "all" the sex hormones. However, the ratios are

this "opposite" hormone that the ovaries would not.
Label the endocrine glands (A-D) A: ______________ B: ______________
C: ______________ D: ______________ - ANSWER >>>>>A: Thyroid
gland B: Adrenal gland C: Kidney D: Pancreas
3. Label the endocrine glands (A-C) - ANSWER >>>>>A: Pineal gland B:
Hypothalamus C: Pituitary gland
Explain the concept of negative feedback and how it helps to maintain
homeostasis. - ANSWER >>>>>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. - ANSWER >>>>>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.
