What else can I help you with?
Is a cell wall semi permeable?
No, they are fully permeable, i.e. liquids and other things can pass through them fully. The cell membrane is what's semi permeable.
Is a piece of aluminium foil a permeable membrane?
depend upon your choice , hydrogen permeable but water not
Are cell membranes permeable or semi-permeable?
Cell membranes are semi-permeable, meaning they allow certain substances to pass through while blocking others. This selectivity is facilitated by proteins embedded in the membrane that regulate the passage of specific molecules based on size, charge, and other properties.
Type of tubing that is semi-permeable?
Semi-permeable tubing is made of materials that allow certain substances to pass through while blocking others. This type of tubing is commonly used in medical devices such as dialysis machines to filter out waste products and excess fluids from the blood. Examples of semi-permeable membrane materials include cellulose acetate and polyethersulfone.
Is an egg shell permeable to salt?
no because the when you dissolve the egg's shell you get the egg's semi-permeable membrane. A way to test this out is take an egg and stick it in 140 mL of vinegar and let it soak for 24 hours. Then you take 140 mL of water and put the egg in that. After 24 hours you see that the egg is "plump". Then you can put the egg in 140 mL of corn syrup. After 24 hours, you see that the egg looks "deflated". If you you were to try this with out the vinegar, then the egg's shape and mass would stay the same.
What is an egg that holds fluid that protects the embryo?
The answer is Amniotic egg.
What does it mean to be semi permeable?
Permeable mean that it is full time. Semi-permeable is when it is only part of the time.
What is a shell membrane?
A shell membrane is a thin, semi-permeable layer that is found beneath the outer shell of some eggs. It helps protect the egg from contamination and helps regulate the exchange of gases.
What is the definition of semi-permeable?
Semi-permeable means partially permeable. The term semi-permeable is composed of two words -semi and permeable. Semi is prefix in Latin and means half, or incompletely or somewhat. Permeability refers to the quality of diffusion or seeping or penetrating. This quality is generally associated with liquids or gases. Thus, semi-permeable is used to describe something that allows the passage of some substances and blocks other or not required substances.
What is the difference between semi-permeable and impermeable?
semi permeable lets some substances through and impermeable lets no substances through
An example of semi-permeable?

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."
Is the small intestine semi permeable?
yes. semi-permeable refers to anything that can be permeated by one type of thing but not another. Most of the nutrients in our food pass through the small intestine, but most of the water (not to mention poop) does not, therefore it is semi-permeable.
What does seminpermeable membrane do?
semi permeable membrane is semi-permeable or not completely permeable...it allows particles of a certain shap or size flow through but other shapes that are large or snaller cant fit through.
How is semi permeable different from permeable?
I think that the difference is that a semi-permeable allows only certain things to pass through which are those that are small enough while permeable again i say i think allows almost all things to pass through
Is a cell wall semi permeable?
No, they are fully permeable, i.e. liquids and other things can pass through them fully. The cell membrane is what's semi permeable.
Is a piece of aluminium foil a permeable membrane?
