Answer:
Clomid tricks the body because it tells the brain that estrogen levels are low, thereby leading to higher production of this hormone  
Explanation:
There are many types of hormones that are regulated by the negative feedback mechanism (where hormone feeds back to decrease its production). Clomid is a drug used to treat female infertility by making the body think that the concentration of estrogen is low, which induces the secretion of Follicle-stimulating (FSH) and luteinizing (LH) hormones by the pituitary gland. The estrogen hormone exerts negative feedback on the Gonadotropin-releasing (GnRH) hormone, which is responsible for the release of FSH and LH. High FSH levels stimulate the growth of follicles in the ovaries, which will be released during ovulation.

Explanation:
Invasive species ruin habitats because they have no natural predators, so they grow and mooch off of native species which kills them off.

D) energy demands triggering a release of glucose.
Notice how the stimulant (low energy supply) triggers a restoration (normalizing) of a normal balance, which in this case is increasing energy supplied (glucose). 
This process is called "homeostasis," or maintaining an internal balance.
