Explanation / Answer

6. Option 4 is correct

Explanation: More offspring are produced than can survive. Organisms are capable of producing more offspring than their environments can support. Thus, there is competition for limited resources in each generation.

7.Option 3 is correct

Explanation: Darwin proposed that species can change over time, that new species come from pre-existing species, and that all species share a common ancestor.

In this model, each species has its own unique set of heritable (genetic) differences from the common ancestor, which have accumulated gradually over very long time periods.
