Answer:
A) polar
Explanation:
Polar molecules contains partial positive and partial negative charge as in all polar molecules two atoms have unequal sharing electron. Due to unequal sharing of electrons, one atom that attracts valence electrons strongly gains positive charge and other gain negative charge.
For example water, water is a polar molecule having partial negative and partial positive charge because the oxygen atom in water attracts electrons more strongly than the hydrogen atoms.
Hence, the correct answer is "A) polar".
Active transport is the movement of dissolved molecules into or out of a cell through the cell membrane, from a region of lower concentration to a region of higher concentration. The particles move against the concentration gradient , using energy released during respiration .
