How might the size of the membrane pore compare to the size of the starch molecules?
In other words this question asks if the pores are bigger or smaller than the iodine molecules. So.... the answer is that the iodine are smaller than the pores and the pores are bigger, because the iodine molecules need room to pass through, and the pores are not selectively permeable because they let the iodine through.
What else can I help you with?
Why might plant storage organs (such as fruit or tuber) contain both starch and sugar?
Starch and sugar are essentially the same thing. Starch is a polymer (chain) of single sugar molecules. As the starch is made up or broken down, you would expect to find both in the cells responsible for this action.
What is another form of transport that uses transport proteins to move other ions and small molecules across the plasma membrane?
This process of transportation might be diffusion. Diffusion, by definition, is the process by which molecules spread out, or move from areas where there is a high concentration of molecules to an area where there is a low concentration of molecules.

What might happen if a disease caused a plasma membrane to thicken?
If a disease caused a plasma membrane to thicken, it could disrupt the exchange of molecules in and out of the cell. This could lead to issues with cellular communication, nutrient uptake, and waste removal. Ultimately, it could result in cell dysfunction and potential cell death.
What is osmoius?
It seems like there might be a typographical error. However, if you meant to ask about "osmosis," it is the process by which molecules pass through a semi-permeable membrane from a less concentrated solution to a more concentrated one, in order to balance out the concentrations on either side of the membrane.
Which component of the cell membrane might contribute to maintaining the fluidity of plasma membranes under freezing conditions?
Cholesterol is a component of the cell membrane that helps maintain fluidity under freezing conditions by preventing the phospholipid molecules from packing too tightly together. Cholesterol acts as a buffer, allowing the membrane to remain flexible at low temperatures.
What might be a result of a disease that causes thickened plasma membrane?
Decreased movement of molecules entering the cell

Why can sugar molecules can pass the lining of the intestine but starch molecules can't?
because the sugar compound inside each grain is less stickier to the sides of the organs inside your body, contrary to starch which is incredibly resistant to most liquids. the starch will most likely close up the inside of your body and might cause minor stomache cramps.
What is the name for the cell membrane of a neuron?
The cell membrane of a neuron is called the "neuronal membrane" or "plasma membrane." It separates the interior of the neuron from the external environment and helps regulate the movement of ions and molecules in and out of the cell.
How do molecules that are too large to cross the membrance enter into the cell?
Large molecules can enter a cell through endocytosis, where the cell membrane folds around the molecule, forms a vesicle, and brings it into the cell. This process allows the cell to take in nutrients, signaling molecules, and other substances that are too large to pass through the membrane directly.
What physical property of the dialysis tubing might explain its differential permeability?
Dialysis tubing is an impermeable membrane/containment vessel that is stratified with microscopic holes which restrict certain molecules or particles from diffusing through them. This leads dialysis tubing to serve as a selectively permeable membrane because it selectively prevents certain molecules from crossing the membrane based on the size of the molecules. (Typically water and glucose will diffuse through, whereas starch and potassium iodide will not.

When a protein channel allows molecules to cross through the cell membrane?
when a protein channel allows molecules to cross through the cell membrane this is called facilitated diffusion. many might mistake this for diffusion which is the process by which molecules tend to move from an area where they are more concentrated to an area where they are less concentrated.

Is it true all cells have a cell membrane?
Yes, all cells have a cell membrane. The cell membrane is a vital component of the cell that encloses and protects the cell's contents while also regulating the movement of molecules in and out of the cell.
