Which part of the cell surrounds the cell and allows molecules in and out this cell part also has holes in it and is said to be semi-permeable?

The cell membrane is the thing that surrounds the cell. The cell membrane contains proteins that allow active transport of molecules in and out of the cell.

How does semi permeable work?
it's like a paper with very small holes So water molecules can pass though it but other molecules like sugar can't because they are too big. That is also how osmosis works. Because the cellwall is semipermeable!
How are electron holes in the molecules filled?
first, the electron holes are filled with electron guillotine called flumenya, then the air absorbs the flumenya creating a hard substance called tiddita
How does water pass through a cell membrane?
Yes, cells have a selectively permeable membrane that allows liquids, and other chemicals to pass through, depending on the concentration inside the cell. The process of water moving from areas of higher water concentration to areas of lower water concentration is 'osmosis'. Also learn to look things up on wikipedia.
What part of the nucleus envelope allows them to get out of the nucleus?
Nuclear spores allow entry and exit.They are holes in envelop.
Describe how the strong force attracts nucleons?
nucleons are made of nuclear molecules. these specific types of molecules are sensitive to strong forces like gravity and other forces like black holes.

What type of energy surrounds black holes?
Hawking radiation and a whole lot of everything else.
How are the ozone layer holes caused?
Ozone holes are the thinning of ozone molecules. This is caused by man made or natural processes.
What has a lot of holes yet it holds many molecules of water?
A sponge
What does selectively permeable mean?
Selective permeability relates to the properties of a membrane. It allows the passage of some substances and not others. Theoretically, it can be thought of as a sheet with holes of a set size in it. Only objects that are smaller than these holes will be able to pass through the sheet. In a proper membrane the 'holes' are usually a type of protein channel that can control permeability by charge as well as size.
Is making a cup of tea an example of diffusion or osmosis?
Diffusion is the correct answer as a tea bag is a fully permeable surface. (Unlike Cellophane and other semi permeable membranes). Osmosis is the process where water passes through a semipermeable membrane.
Do water molecules have holes?
It could be said that water molecules do have "holes", although a better term would be empty space. This is why compounds like sugar and salt can dissolve in water, as well as some other chemical properties that make this possible.
If a membrane was not permeable to sugars why would it probably also not be permeable to starch molecules?
If a membrane is permeable to a substance, it means that there are gaps/holes/pores in the membrane large enough for that substance to pass through. Starch molecules are bigger that sugar molecules. So if the membrane is not permeable to sugars, the gaps/holes/pores will not be big enough for starch molecules to pass through either.
How does Jason look without his mask?
hi probably has holes in his that allows him to see
What does selective permeability mean what is responsible for the selective permeability of the plasma or cell membrane?
When a cell's membrane is permeable, it means that only certain proteins and other molecules can go in and out of the porous membrane, through protein pumps and other pathways. Some molecules stay inside the cell, while others float outside. Starches, for example, are large molecules that cannot pass through the membrane.

first, the electron holes are filled with electron guillotine called flumenya, then the air absorbs the flumenya creating a hard substance called tiddita
