Kisspeptin is a protein in humans that has an important role in initiating secretion of the releasing factor gonadotropin-releasing hormone (gnrh). endocrinologists are finding that the protein kisspeptin and its receptor are central to sexual maturation at puberty. neurons that release kisspeptin carry estrogen receptors. if this is a negative feedback system, high levels of estrogen would be expected to:

the electromagnetic spectrum includes, from longest wavelength to shortest: radio waves, microwaves, infrared, optical, ultraviolet, x-rays, and gamma-rays.

kelp are large brown algae that live in cool, relatively shallow waters close to the shore. they grow in dense groupings much like a forest on land. these underwater towers of kelp provide food and shelter for thousands of fish, invertebrates, and marine mammal species.
