Question

a biology teacher placed a chicken egg in vinegar to dissolve the shell, exposing the cell membrane. sodium chloride (salt) in water in order to demonstrate cellular transport. the teacher recorded the ma what is the change in mass demonstrating?

oa facilitated diffusion

ob active transport

oc filtration

od osmosis

Explanation:

Osmosis is the movement of water across a semi - permeable membrane from an area of lower solute concentration to an area of higher solute concentration. In this experiment, with the egg membrane acting as a semi - permeable membrane and a salt - water solution creating a solute gradient, the change in mass is due to water movement via osmosis. Facilitated diffusion involves transport proteins for specific molecules, active transport requires energy and moves substances against the concentration gradient, and filtration is based on hydrostatic pressure differences.

Answer:

D. osmosis
