Which statement concerning osmosis and active transport is correct?

question 4 options:

neither facilitated diffusion nor osmosis requires cell energy.

diffusion of gases and other small molecules requires no energy on the part of the cell.

active transport requires cell energy and osmosis doesn't.

both endocytosis and active transport require cell energy.

Active transport requires cell energy and osmosis doesn't is the statement concerning osmosis and active transport that is correct.

Active transport is the movement of dissolved substances across a cell membrane from a region of lower concentration to a region of higher concentration. Active transport requires an input of cellular energy to perform the movement, while osmosis is a form of passive transport which involves the movement of molecules through a semipermeable membrane from a region of higher concentration to a region of lower concentration without the use of energy.

the genotypes would be 50% bb and 50% bb

the phenotypes would be 50% brown and 50% white. hope this : )

try using substitution:

x + y - 6 = x - y. (i'm not giving you the exact answer). since 0 = x - y, then sub 0 in the equation with x - y. combine your like terms, and then use inverse operations, and you'll have your answer.
