What is a replicated chromosome and how many DNA stands can we expect?
It is when the chromatid is replicated into two strands. making an X shape. This means we have two stands of DNA

What makes secondary succession different from primary succession?
What is the stage the succession is produced at. Secondary succession usually has soil or some species still living while primary is from the very beginning with bare rock.
