Answer:
AQUAPORINS dramatically increases the rate of diffusion of water across cell membranes.
Explanation:
Aquaporins are integral membrane proteins also called water channels that forms pores in the membrane mainly for facilitating diffusion of water molecules in and out of the cell. Aquaporins selectively allow the passage of water molecules while preventing the passage of ions and other solutes through it as they are impermeable to protons, and large solutes. These proteins therefore increases the permeability of the membrane to water molecules and the rate of diffusion of water increases through them. Flow of water molecules in aquaporins follows the direction of osmotic pressure across the membrane. Aquaporins in some organisms have been modified to voltage gated aquaporins which helps them to close the water channels in unfavorable conditions such as drought and flooding. This is to prevent excessive loss of water to the surrounding or intake of water into the cells.

Traveling wave is a wave that is not confined to the space along medium.
traveling wave is a wave that travels along the medium causing disturbance. instead of vibrating at the same place, the particles actually move in the direction of wave. one common example of such type of wave is ocean waves.
