Which phrase best describes the property of selective permeability?

Biology

belka [17]3 years ago
4 0

Answer:

some molecules pass

Explanation:

The ability of a membrane to pass or not to pass a substance is its permeability (permeability).

Permeability is, in fact, the ease with which a dissolved particle passes through the membrane, which depends on both the properties of the particles and the properties of the membrane itself.

The membrane is semipermeable (semipermeable) or selectively permeable because it does not permeate all molecules.

Platelets start a clotting reaction that intimately produces a clot composed of fibrin, is a form of Fibrinogen

Explanation:

Fibrinogen is blood plasma Protein which is converted into those protein fibrins in the clotting process. After removal of clot the fibrinogen free fluid is obtained and this fluid is known as blood serum. It shows strong flow birefringence. It is highly viscous.

By half saturation process and using the sodium chloride fibrinogen can be participated from the blood plasma. Through thrombin process clotting is initiated. With the help of electron micrographs, its molecules look like a rod whose length is 47.5 nanometre.
