Biological membranes are said to have what When some substances can pass across them but others cannot?
Semi-permeable membranes, crucial to osmotic processes.
When some substances can pass across them but others cannot biological membranes are said to have?
They are said to have semi-permeable membranes.That is,they allow some substances to pass through & prevent others due to the nature & composition of that substance.
What substances can pass across them but others cannot?
semi-permeable membranes
What does it mean to say most biological membranes are selectively permeable?
Selectively permeability is a property of biological membranes that allows them to regulate the passage of substances across them. In spite of heavy traffic through them, cell membranes are selectively permeable, and substances do not cross the barrier indiscriminately.

When some substances can pass across them but others cannot?
membrane
Does it mean that biological membranes are selectively permeable?
means they allow some things to cross, but not others.
Does a permeable membrane will let substances pass through it?
Yes it does permeable membranes are membranes that allows all substances to pass through.
Can all particles move across the cell membrane?
no, membranes are selectively permeable, letting somethings in and not others
What does Osmosis includes?
All the actions of semiperiable membranes : surfaces that allow some materials to pass through but not others. USUALLY the term osmosis refers to membranes that pass water but not other substances.
What is a membrane that allows some substances to pass through but excludes others?
A membrane that lets some substances pass through but not others is known as a semipermeable membrane. Other terms that describe this type of membrane are: selectively permeable, partially permeable, or differentially permeable.
What membranes are there in osmosis?
Semipermeable membranes are used in osmosis. Semipermeable membranes let some molecules pass through them but not others, so they are partially or semi permeable. For example, the membrane may let smaller size molecules pass though but block larger molecules sort of like a sifter. Thus the two molecular substances can be separated.
