What else can I help you with?
How could you test to see if a membrane was semi-permeable to a substance?
To test if a membrane is semi-permeable to a substance, you can set up a diffusion experiment using two compartments separated by the membrane. Fill one compartment with a solution containing the substance and the other with a solvent. Over time, measure the concentration of the substance in the solvent compartment; if it increases, the membrane is semi-permeable to that substance. Additionally, you can compare the rate of diffusion of different substances to determine the selectivity of the membrane.
How do you differentiate salt and sugar?
Yes. You could try melting it over a Bunsen burner - the sugar will melt readily whereas the salt will not. You could also try dissolving the substance in alcohol. The salt will dissolve only very slightly, but the sugar will dissolve readily.
What would happen if the plasma membrane were made primarily of a hydrophilic substance such as carbohydrate?
If the plasma membrane were primarily composed of a hydrophilic substance like carbohydrates, it would disrupt the membrane's ability to create a hydrophobic barrier. This could lead to uncontrolled movement of water and solutes into and out of the cell, compromising cellular integrity and function. The inability to maintain a stable internal environment could also affect cellular signaling and interactions with the environment, ultimately jeopardizing the cell's survival.
Where in the membrane does facilitated diffusion occur?
Diffusion will most likely to occur where there is a high concentration of gas or water then the particles distibute evenly to the area of low concentration. for example if you could smell a turkey cooking in the oven from upstairs without anyone telling you.
What would happen if the cell wasn't permeable?
the cell membrane is not completely permeable.This allows substances in and out of the cell and only a few substances could get into the cell.If the cell membrane becomes permeable any substance including the bad ones will get in easily this could destroy the cell.

How do carrier proteins help substances enter the cell?
Carrier proteins facilitate the movement of substances across the cell membrane by binding to specific molecules and transporting them through the membrane. This process is known as facilitated diffusion and helps substances enter cells by bypassing the lipid bilayer barrier.

Yes. You could try melting it over a Bunsen burner - the sugar will melt readily whereas the salt will not. You could also try dissolving the substance in alcohol. The salt will dissolve only very slightly, but the sugar will dissolve readily.
What are two reasons why a substance cannot make it through the lipid bilayer?
One reason a substance may not pass through the lipid bilayer is if it is too large or too charged to navigate the hydrophobic interior. Another reason could be if the substance is not lipid-soluble, as non-polar molecules are typically required for passive diffusion across the membrane.
Why is it important for the nutrients to pass through the cell membrane?
If they could not then the cell would starve.
What particles could diffuse easily through a cell membrane sodium and oxygen?
Oxygen (O2)

What would happen if molecules could not pass through the cell membrane?

What can you conclude about the cell membrane structure if liquid soluble molecules move across the membrane?
It can be concluded that if the liquid soluble molecules move more readily across the membrane then the membrane must be made of lipids. When two parts are made of similar material then they will be more likely to allow other particles like them to pass.
How would you design a cell membrane that would allow you to move more material through the membrane faster without taking more space?
One way to increase the speed of material movement through a cell membrane without taking up more space would be to incorporate more channels or transport proteins. These proteins can facilitate the movement of specific molecules across the membrane more efficiently. Another approach could be to increase the fluidity of the membrane by incorporating more unsaturated fatty acids, which would make it easier for molecules to move through the membrane. Lastly, increasing the surface area of the membrane through invaginations or microvilli could also enhance material transport.
