Because of the Endangered Species Act, the sale of protected animals or plants is - correct
answer-punishable by a substantial fine.
Earth's various organisms appear to be - correct answer-concentrated in certain biomes.
Germ plasm is - correct answer-the genetic material of a species.
Germ-plasm banks are unique because they focus on - correct answer-storing genetic
material.
How can zoos, botanic gardens, and wildlife parks help save species? - correct answer-by
preserving threatened species from destruction. and by participating in captive breeding
programs.
How many species are estimated to be living on Earth? - correct answer-between 10 and 50
million

humans.
The ecosystem approach to conservation is partly based on the idea that - correct answer-a
healthy biosphere requires intact ecosystems.
The fact that organisms are adapted to survive in particular environments helps to explain
why - correct answer-habitat destruction accounts for most extinctions.
