This question is incomplete but the completed question is below

The Nature Conservancy is an organization that  protects a variety of habitats around the world.  A project this organization would probably  support is one that

(1) uses endangered animals for medical research

(2) protects the biodiversity of areas for future  generations

(3) alters habitats for industry and housing

(4) prevents animal species from migrating to  other habitats

The correct answer is (2)

Explanation:

Protecting habitats (which is the main "support" of this organization) will have to do with ensuring organisms live and are comfortable in the natural habitat they are found without or protected from "transgression" by humans and other possible biotic and even abiotic factors. Since, different organisms will normally live together in a community in order to "satisfy" the food chain and survive, this organization will most likely support projects involving the protection of biodiversity in different areas of communities of organisms for these organisms' future generations.

clorine is a compound its a chemical substance that forms when two or more different elements combine

so both hydrogen and clorine are compounds
