What else can I help you with?
What is difference between RO and distilled water?
Distilled implies boiling, Reverse osmosis implies the use of semi-permeable membranes. I say "implies" because there's a lot of cheating in the bottled water industry.
What is an example of a selectively permeable?
A selectively permeable cell membrane allows certain molecules or ions to pass through it by means of active or passive transport. The most common example is the phospholipid bilayer cell membrane that surrounds all of our body cells. The inner membranes of an egg are also selectively permeable membranes.
Why Cell membranes are not permeable to anthocyanin. If the anthocyanin appears in the solution what must have occurred?
Cell membranes are not permeable to anthocyanins due to their large size and polar nature, which prevent them from easily passing through the lipid bilayer. If anthocyanin appears in the solution, it suggests that the cell membranes have been compromised, possibly through damage or the use of solvents that disrupt membrane integrity, allowing the anthocyanin to leak out of the cells.
Why do you use dialysis tubing as a model for a cell membrane?
Dialysis tubing is used as a model for a cell membrane because it is selectively permeable, allowing only certain molecules to pass through, just like cell membranes. This property helps in studying processes like osmosis and diffusion in a controlled environment that mimics the behavior of cell membranes.
How do you use porous in a sentence?
The porous texture of a sponge made it easier to absorb liquids. (it might work)
What is the difference between a permeable and a semi permeable membrane?
There is no real difference other than the wording; both semi-permeable and partially-permeable mean the ability to allow some substances to pass.However, OCR examiners for AS Biology have said that you should "not use the term semi-permeable when referring to cell membranes that allow water and other solutes to cross them" but should "refer to them as partially permeable."
What is the difference between a semi-permeable and a partially permeable membrane?
An impermeable membrane is that through which no substance can pass. Semipermeable membranes are those that let only solvents, like water, to pass through it. Permeable membranes are those that let solvent and solutes, like ions and molecules, to pass across it. There are also selectively permeable membranes, i.e., membranes that besides allowing the passage of solvent, let only some specific solutes to pass while blocking others. See link:

How do you use the word permeable in sentence?
Something that is permeable has pores through which gas or liquid may pass or be absorbed through. An example would be, "A sponge is permeable because it can absorb water." or "Some cellular membranes are permeable."

Do both osmosis use of a channel?
Osmosis is a passive process that does not use channels. It involves the movement of water molecules across a semi-permeable membrane from an area of high concentration to an area of low concentration. Channels, on the other hand, are specific proteins that facilitate the passage of ions and molecules across cell membranes through active transport mechanisms.
You would use' ' when you want to?
Selective Media - Our cell membrane has a selective permeable property. This type of membranes are important when we want to allow certain sized particles to enter while restricting other sized particles to enter our cell. Selective permeable membrane is of great use in biological samples.

Why do you use osmosis?
Osmosis is used to balance the concentration of solutes on both sides of a semi-permeable membrane. This process is important for regulating the movement of water and nutrients across cell membranes to maintain proper cell function and overall body homeostasis.
