A.

B.
The oils in the lotion enter the skin cells with the help of carrier proteins.
C.
The oils in the lotion enter the skin cells by means of facilitated diffusion.
D.
The oils in the lotion enter the skin cells by means of simple diffusion.

Answer 1

The correct answer is D the oils in the lotion enter the skin cells by the means of simple diffusion.

Step-by-step explanation:

Lipid molecules that are rich in unsaturated fatty acids exist as oil in biochemical system.

As the oils are rich in fatty acids that means they are hydrophobic in nature.For being hydrophobic it will be very easy for the oils present in the lotion to enter the skin cells by means of simple diffusion.
