Answer 1

A

Step-by-step explanation:

Facilitated

Answer 2

This is type of transpor tis known as facilitate diffusion

Step-by-step explanation:

Facilitate diffusion is one of the most important membrane transport process in both plants and animals.Facilitate diffusion helps in the transport of polar molecules such as water by the help of a channel protein known as aquaporin which act as transmembrane protein.

Facilitate diffusion helps in the the transport of water molecules from high water concentration region to region of low water concentration untill the solute concentration of both compartment become same . As the water molecules is transported towards their concentration gradient no additional energy is required in this transport process.
