Part a - hormonal control of the ovarian cycle in humans hormones control the two closely linked reproductive cycles in human females—the uterine (or menstrual) cycle and the ovarian cycle. during one uterine cycle, which is approximately 28 days long, the lining of the uterus undergoes hormonally-regulated changes, if no pregnancy has occurred. at the same time, the hormones also cause a series of changes to take place in an ovary, known as the ovarian cycle. the flowchart below describes the events of the ovarian cycle. drag the names of the hormones to their appropriate locations on the flowchart, starting with the release of a hormone from the hypothalamus. labels may be used once, more than once, or not at all. (note: gnrh = gonadotropin-releasing hormone; lh = luteinizing hormone; fsh = follicle-stimulating hormone.) view available hint(s) gnrh estradiol oxytocin lh and fsh estradiol and progesterone submit provide feedback next

Examine the two squirrel populations in the accompanying figure. the populations are separated by a geographic barrier. if after a long period of time the two species are no longer separated, what evidence is needed to determine if speciation has occurred? the figure shows two populations of squirrels separated by a geographic barrier. examine the two squirrel populations in the accompanying figure. the populations are separated by a geographic barrier. if after a long period of time the two species are no longer separated, what evidence is needed to determine if speciation has occurred? the figure shows two populations of squirrels separated by a geographic barrier. polyploidy is creating new species. the two populations are not interbreeding freely. hybrid offspring of the two populations begin to appear. one species will increase into a population size twice as large as the other species.
