The question is incomplete as it does not have the options which are:
- estradiol; pituitary gland
-
testosterone; hypothalamus
-
leptin; hypothalamus
-
leptin; pituitary gland
Answer:
leptin; hypothalamus
Explanation:
Gonadotropin hormones are the peptide hormones released by the nerve cells of the hypothalamus which stimulates the anterior hormone to release the gonadotropins like the LH and FSH hormones.
The GnRH hormone is released when the leptin, a protein hormone secreted by the adipocytes stimulates the GnRH neurons of the hypothalamus to release the hormone in both males and females.
Thus, leptin; hypothalamus is the correct answer.
And the peripheral nervous system
Answer: Food terrorism

Any unintentional or deliberate contamination of food which csn have an effect on human health is food terrorism.
Food terrorism can be threat whereby the food that's meant for people to.eat is contaminated deliberately with biological or chemical agents in order to cause injury or death to people and thereby disrupt the social or political stability.

The odorant molecules arrive either directly by diffusion into the mucus, or are supported by transport proteins (odor binding protein or OBP) that allow the hydrophobic molecules - majority - to penetrate the mucus covering the epithelium, and thus to reach the membrane receptors present on the eyelashes of the olfactory neurons. These transport proteins are thought to concentrate odorant molecules on membrane receptors. As ligands, the odorant molecules bind to membrane receptors on the eyelashes, triggering a transduction pathway for a stimulus involving G.olf protein (first messenger), adenylate cyclase, and cAMP ( second messenger). The second messenger causes the opening of ion channels Ca2 + / Na + present on the plasma membrane of the olfactory receptor, these two ions then enter the cell. Ca2 + causes the opening of a Cl- channel, the output of this ion causes depolarization of the membrane so that the olfactory receptor produces action potentials. These impulses will go directly to the olfactory bulb, in the prefrontal region of the brain, where this information (and that of taste) is processed by the body.
