BIOD 151 Module 6 Exam (100% Error-free Answers)
Explain two reasons why a woman with low levels of LH would not be able to become pregnant.
correct 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.
correct 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: ______________ correct answers A: Thyroid gland B: Adrenal gland C: Kidney D: Pancreas
3. Label the endocrine glands (A-C) correct answers A: Pineal gland B: Hypothalamus C:
Pituitary gland
Explain the concept of negative feedback and how it helps to maintain homeostasis. correct
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. correct 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.
