On the top of a high mountain, air pressure is significantly lower than at sea level, so there is less O2 in a given volume of air. Suppose a person at high altitude maintained the same rate and depth of breathing as he had at sea level. What would happen to the O2 levels in his blood? Explain your reasoning, using the vocabulary: breathing rate, oxygen, lungs, blood.

an adaptation is a change or process by which an organism takes to be better suited for its environment. for example; migration is a behavioral adaptation, this is needed because birds are not built to last extremely cold climates. there are different adaptations because there are different species needing to adjust to different things, bears don't migrate; they hibernate.

they both go up but then go back down. they both end lower than they started. lastly, they both are competitive/the second on.
