When an aquatic mammal begins to dive, it actually exhales and pushes oxygen out of its lungs. This decreases its buoyancy so it doesn't have to use as much energy to fight the tendency to rise to the surface. So, how can these animals stay under for so long if they aren't "holding their breath?" Observe the following graphs. Compare where the 3 animals (2 mammals and 1 bird) store their oxygen.

Which muscle is responsible for inhalation ?

6. in domesticated cats, the following are independently assorting: normal ears (t) is dominant to tufted ears (t); curved whiskers (c) is dominant to straight whiskers (c); the presence of six toes (s) is dominant to five toes (s); gene for hair length is an x-linked codominant. the three phenotypes for hair length are long (xhxh), medium (xhxh), and short (xhxh); medium is the heterozygous condition. given two parents: ttccssxhxh x ttccssxhy how many different gametes could be formed in the female cat with respect to these four traits? how many phenotypes are possible in the offspring from this mating?
