Question

1. explain how the egg represents a cell with a semi - permeable membrane?

Explanation:

An egg has an outer shell and a membrane beneath it. Just like a cell's semi - permeable membrane, the egg membrane allows certain substances (such as water) to pass through while restricting others. Osmosis can be demonstrated with an egg, where if placed in a solution with a different solute concentration, water will move across the membrane, similar to how substances move across a cell membrane.

Answer:

An egg has a membrane that allows some substances to pass through while restricting others, similar to a cell's semi - permeable membrane, and can demonstrate osmosis like a cell membrane.
