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 a visking tubing differ from a cellmembrane?
Visking tubing contains millions of tiny holes which only let small molecules, like water, diffuse through. Large molecules, such as starch, cannot cross the membrane. We say it is partially permeable (permeable means a substance is able to pass through). This is similar to a cell membrane. Visking tubing can therefore be used as a model of a cell.
36g of water have how many molecules?
36g water contains 12.046 x 1023 molecules.
Is water made of atoms or molecules?
Waters is made of molecules. Each of those molecules contains 3 atoms.
What does crude oil contain?
Crude oil contains a mixture of hydrocarbons molecules
In what types of cells do you find large numbers of ribosomes?
Large numbers of ribosomes are present in cells that specialize in producing protein molecules. The mitochondrion contains its own DNA and ribosomes.
Which organelle contains inner membranes called cristae?
mitochondrion
What contains their own DNA which encodes some of their proteins?
Chloroplasts; Mitochondrion

An underground layer of permeable material that contains groundwater is called?
aquifer
If a beaker contains glucose and is permeable to glucose what will happen to the glucose?
If a beaker containing glucose is permeable to glucose, then the glucose will go through the beaker.
What is the functions to the cell membrane?
The Cell membrane contains the insides of the cell. The membrane is also selectively permeable, allowing nonpolar molecules to simply diffuse into the cells, such as lipids, steroid based hormones, CO2, etc. It also allows small polar molecules to diffuse through, such as H2O.
What cell contains enyzmes DNA ribosomes plasma membrane and mitochondrion?
Sounds like a eukaryotic cell.
List each container that contains molecules?
There are two containers that contain molecules. Container a and container b. Container a contains carbon dioxide, and container b contains water and carbon dioxide molecules.
What is frog body covering?
Frogs have a permeable skin wich contains mucusglands and poison glands.
An underground layer of permeable material that contains groundwater is called aan?
It is called an aquifer.
