Question

A. True

b. False in passive transport, molecules can only move with the net movement of molecules down their concentration gradient

Answer 1

Passive transport requires no energy so moves with the gradient, not against it (active transport) so it is true

Answer 2

This statement is true. Only active transport can move molecules up a concentration gradient using energy. Passive transport on the other hand, uses no energy and occurs naturally. Therefore molecules can only move a concentration gradient.
