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:)
What best explains whether bromine or neon is more likely to form a covalent bond? <span>Bromine forms covalent bonds because it has seven valence electrons, but neon has eight valence electrons and already fulfills the octet rule.
Hope This Helps :) </span>

The study of the interaction of organisms with each other and their environment involves non-living factors, also called abiotic factors, and living factors, which are referred to as biotic factors.
This study called ecology focuses on several things about the ecosystem, which is a group of organisms interacting with each other and their environment. Ecology is a very broad field that encompasses the study of everything concerning the the world's inhabitants and how they behave in their surroundings.
