What does semi permeable membrane do?
I semi-permeable membrane is a membrane when only certain substances can pass through it.it is a membrane that will only allow certain molecules through it . in general oxygen , food and water are allowed to enter ; waste products are allowed to exit and harmful substances are kept out. hope this helps.
What does it mean when something is semipermeable?
When something is semipermeable, it means that it allows only certain substances to pass through while blocking others. This selective permeability is due to the size, charge, or other properties of the molecules trying to pass through the barrier. An example of a semipermeable membrane is the cell membrane, which allows only specific molecules and ions to enter and exit the cell.
The nucleus is surrounded by a semipermeable membrane. what would happen if this layer were permeable to most substances?
Large molecules would be able to enter and damage the nucleus.

Why would a saltwater fish die in freshwater?
This is all due to osmosis. If a saltwater fish is placed in freshwater, its polar molecules, in this case salt, attracts the other water molecules around the fish, which has no polar molecules, for it is fresh water. The water molecules enter the body so they can hang out with the salt molecules, and enter the fishes cells through the cell membrane, which is semipermeable, which means that only certain molecules, such as water, can pass through it. When the water enters the cells, which are already filled with water, they become hypertonic, and burst, causing the fish to die.

What is the definition for selective diffusion?
Selective diffusion refers to the process in which only certain molecules are able to pass through a semipermeable membrane based on their size or charge. This process allows the cell to regulate what substances can enter or leave the cell.
What cell organelle has pores that allow certain molecules to leave and enter it?
Cell membrane
What structure allows only certain things?
A filter or a gatekeeper can be a structure that allows only certain things to pass through. These structures help control and regulate what is permitted to enter or proceed.
Which part of a cell controls which substances can enter?
The cell membrane. It is described as semipermeable
Is anyone allowed into the Taj Mahal?
Yes. Anyone can enter. You can be there between sunrise and sunset and you are only allowed in certain rooms and galleys
Why do you think that the eggs membrane will let water to enter but not corn syrup?
water molecules are smaller than corn syrup. the membrane allows a certain size of molecules.
