Explain two reasons why a woman with low levels of LH would not
be able to become pregnant. - correct answer -(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.

bloodstream? Explain why or why not. - correct answer -(1) Yes.

Explain the concept of negative feedback and how it helps to
maintain homeostasis. - correct 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. - correct 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.
