<span>The choices can be found elsewhere and as follows:
</span><span>a)folded mountains
b)fault-block mountains
c)canyons
d)plateaus</span><span>
I think the correct answer is option B. Mountains that have developed because of compressional stress—colliding plates that force rock layers upward—are called </span>fault-block mountains.
A primary active transport process is one in which MOLECULES MOVE THROUGH TRANSPORT PROTEINS THAT HAVE BEEN ACTIVATED BY ATP.
