Document Summary
Increase o2 stores (hemoglobin, high levels of myoglobin, lungs) b: readjust o2 demands, expel rbc stored in spleen, dive response (forced lab diving, avoiding predator in real life) Give an example of each: r-type, k-type, reproduction as rapidly as possible, many offspring, little parenting care/investment, ex. Insects: delay reproduction until late in life, to ensure strength to tolerate cost of nurturing young, produce few offspring, heavy parental investment, ex. Give an example in an invertebrate and vertebrate species: virgin birth, using ova and female reproductive system to produce haploid or diploid offspring, female gamete differentiates into embryos without fertilization, ex. Invert: aphids, vert: komodo dragon: describe sex determination systems in vertebrates, sex determination by hormonal signals, xy or zw systems: presence or absence of sex-determining. & subsequent chromosome: xy male is heterogametic, zw female is heterogametic birds, butterflies humans, sex determination by. In mammals, the presence or absence of the y chromosome determines sex.
