What does selectively permeable mean Quizlet?

A selectively permeable material is one through which some substances can pass while others cannot. This is opposed to a non-selectively permeable material, which does not allow any substances to pass through it.

What does selectively permeable mean in chemistry Quizlet?

A material is called selectively permeable if it allows the passage of one type of molecule while keeping out others. Water and oil are two examples of substances that are naturally highly permeable. In contrast, glass is an example of a material that is not permeable to water, while allowing the transmission of light.

What does selectively permeable mean in math Quizlet?

A number is said to be selectively permeable if it can pass through membranes more easily in one direction than in the opposite one. This is the measure of how good a gas or liquid is at passing through a membrane. Another way of looking at it is that a number can “flow” through in one direction but not the other. In the interest of simplicity, people will often use the term permeable to describe a number that can be passed through a membrane and porous to describe something that

What does selectively permeable mean in Quizlet?

It’s all about the membranes. A selectively permeable membrane is porous to some kinds of material but not others. It allows one kind of fluid to pass through it, while keeping others out. A good example is a coffee filter, which allows the passage of water while keeping the ground coffee and other debris out.

What does selectively permeable mean in biology Quizlet?

Cell membranes separate different compartments of the cell from one another. This allows different chemicals and other substances to move in and out of the cell; therefore, the membrane is selective to a certain type of molecule. To be permeable, the membrane allows only specific substances to pass through it. There are two types of membranes: those that are permeable to some substances and those that are permeable to others.
