I'd say first question, "life changes over time".
Second question, "when there are physical similarities in the early stages of embryonic development, it suggests that each of the modern organisms once had a common ancestor".
Third, appendix.
Fourth, "they are evidence that all came from a common ancestor and that life changed over time for all these organisms to exist".
Fifth, "they all share at least 50% of the same DNA arrangement".
I might be a little late but hopefully this helps!

One of the methods used widely to calculate the distance of nearby or closer objects in astronomy is Parallax. The distance of the stars are usually expressed in light years but the unit of distance is parsec or parallax second.
1 Parsec = 3.26 light years
Astronomers are not able to measure the parallax of a star that is a million light years away because the star is too far and the distance with which the start appears to move is too less to be calculated accurately.
