Which definition is the best for “semipermeable membrane”? It is a barrier that prevents materials from moving from one side to
the other. It is a barrier that allows materials to move freely from one side to the other. It is a barrier with tiny openings that let some, but not all, materials pass through. It is a barrier that helps materials move from one side to the other.
A semipermeable membrane is a membrane that allows certain substances to pass through it. The most accurate definition is the third choice, "It is a barrier with tiny openings that let some, but not all, materials pass through." hope this helps:)
Option C, It is a barrier with tiny openings that let some, but not all, materials pass through
Explanation:
A semipermeable membrane is a biological membrane that allows some substances to pass through it. Such type of membranes are also referred as selectively permeable membrane as they do not allow all substances to pass through it non-distinctively.
For example the cell membrane , wall of arteries, wall of intestine etc. are semipermeable membrane.
Decomposers eat dead remains of organisms that are quaternary consumer (no one eats them while alive). So, they break these down and therefore turn into nutrients in the soil for plants to use.
