Question

would it be passive or active transport if particles move from an area of high concentration to an area of low concentration? passive transport active transport

Explanation:

Passive transport is the movement of molecules across a cell membrane without the use of energy. It occurs due to the concentration gradient (from high to low concentration). Active transport, on the other hand, requires energy (usually ATP) and moves molecules against the concentration gradient (from low to high concentration). Since the question describes movement from high to low concentration, it fits the definition of passive transport.

Answer:

Passive transport
