If the movement of substances is from low concentration to higher concentration: *
1 point
it would not require energy
it would still be passive transport
it would require ATP, a form of energy
none of the above

It would require ATP, a form of energy

Explanation:

If the substance is moving from low concentration to high concentration, it would be going against the gradient. For example, if you were riding your bike down the hill (high to low), you would be able to coast down. However, if you were riding your bike up the hill (low to high), you would need to put in energy to pedal up. Hope this helps!

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.

c is the answer. hope this
