strich farms/petting zoos are few and far between, admittedly, but they do exist in places like Picacho, Ariz., and Solvang, Calif., where they produce a special breed of ostrich. Ostriches raised by humans apparently develop feelings for their surrogate parents' species -- feelings that sticklers for interspecies etiquette might deem inappropriate. According to ostrich researchers, both male and female ostriches raised by people are twice as likely to make passes at them. In fact, 70 percent of the studied ostriches flirted (a.k.a. "engaged in courtship behavior") when human visitors came near. The good news is, that behavior consists mostly of elaborate, near-farcical dance moves -- so hold off on the pepper spray and put on your dancin' shoes. The above findings about ostrich mating behaviors align well with the teachings of which famous scientists and theorists that we have learned about in class? a. Erik Erikson and Jean Piaget b. Lev Vygotsky and Jean Piaget c. Konrad Lorenz and Sigmund Freud

Submission 1 (0.67/1 points) Friday, November 3, 2023 11:08 AM CDT Use the definitions of even, odd, prime, and composite numbers to justify your answers for (a)-(c). Assume that r and s are particular integers. (a) Is 6rs even? O Yes, because 6rs = 2(3rs) and 3rs is an integer. O Yes, because 6rs = 2(3rs) + 1 and 3rs is an integer. O No, because 6rs = 2(3rs) and 3rs is an integer. O No, because 6rs = 2(3rs) + 1 and 3rs is an integer. (b) Is 6r + 2s^2 + 3 odd? O Yes, because 6r + 2s^2 + 3 = 2(3r + s^2 + 1) and 3r + s^2 + 1 is an integer. O Yes, because 6r + 2s^2 + 3 = 2(3r + s^2 + 1) + 1 and 3r + s^2 + 1 is an integer. O No, because 6r + 2s^2 + 3 = 2(3r + s^2 + 1) and 3r + s^2 + 1 is an integer. O No, because 6r + 2s^2 + 3 = 2(3r + s^2 + 1) + 1 and 3r + s^2 + 1 is an integer. (c) If r and s are both positive, is r^2 + 2rs + s^2 composite? O Yes, because r^2 + 2rs + s^2 = (r + s)^2 and r + s is an integer O Yes, because r^2 + 2rs + s^2 = (r + s)^2 and r + s is an integer O No, because r^2 + 2rs + s^2 = (r + s) and r + s is not an integer.
