Explain in detail why the thyroid becomes enlarged during an iodine
deficiency
When there is a low level of thyroxin in the blood, the anterior pituitary
continues to produce TSH. The thyroid responds by increasing in size and
producing a goiter, but this increase in size is ineffective because active
thyroxin cannot be produced without iodine

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

Progesterone is a key hormone for the maintenance of pregnancy.
We have an expert-written solution to this problem!
Would you expect a female to have testosterone in their bloodstream?
Explain why or why not.
(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.
Explain the concept of positive feedback.
Give an example of a hormone that works through positive feedback.
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.
