Question

if the semipermeable membrane allows the green chemical to pass through freely, where will the green chemical move? options: left to right, right to left, up and down (with an image labeled elsevier)

Explanation:

This question relates to the movement of substances across a semipermeable membrane, likely due to diffusion (movement from high to low concentration). From the diagram (implied by the Elsevier image, often used in biology for cell membrane transport), if the green chemical is more concentrated on the left, it will move left to right to reach equilibrium.

Answer:

A. left to right
