It's C! It changes as new evidence is found.
Answer:
If the Earth suddenly had no gravity, the Earth’s atmosphere would float into space. Everything not attached to the Earth would fly off into space. Things like trees and most buildings would remain because they are rooted. Since the Earth, itself, is held together by gravity, it would most probably break apart into chunks and float off.
Explanation:
For each of the examples, simple diffusion, carrier, and channel mediated, each type involves the flow down a concentration gradient. This means that the molecules flow from an area of high concentration to an area of low concentration. In turn, this allows for a passive process, meaning no ATP is needed! I hope this explains your question.
