Briefly describe the scenario that was discussed in the behaving brain that demonstrated that the brain can change based on state or mood. which disease could the research involving rats and learning experiments that was discussed in the behaving brain ultimately with? in the behaving brain, what is a common misunderstanding about amnesia that was mentioned? what is the truth about amnesia that's mentioned? what does research discussed in the responsive brain show to be different in men and women's reaction to touch? what was discussed in the responsive brain as being brain-based and a vital part of normal growth and development in young children? in the responsive brain, what do they discuss as a possibility for leading to deficiencies in cognitive impairment as we age? in the responsive brain, what did the research involving african cichlid fish demonstrate? briefly describe the back story and affliction of the author of peter pan. what did you find most interesting about the behaving brain video, and why? what did you find most interesting about the responsive brain video, and w

To answer this question, researchers studied populations of the dusky salamander (desmognathus ochrophaeus) living on different mountain ranges in the southern appalachian mountains. the researchers tested the reproductive isolation of pairs of salamander populations by leaving one male and one female together and later checking the females for the presence of sperm. four mating combinations were tested for each pair of populations (a and b)—two within the same population (female a with male a and female b with male b) and two between populations (female a with male b and female b with male a). the proportion of successful matings for each mating combination was measured. for example, when all the matings of a particular combination were successful, the researchers gave it a value of 1; when none of the matings were successful, they gave it a value of 0. then the researchers calculated an index of reproductive isolation that ranged from 0 (no isolation) to 2 (full isolation). the reproductive isolation value for two populations is the sum of the proportion of successful matings of each type within populations (aa + bb) minus the sum of the proportion of successful matings of each type between populations (ab + ba). the table provides data for the geographic distances and reproductive isolation values for 27 pairs of dusky salamander populations.
