What are the answers oldest to youngest? If you give me a bogus answer than I’m reporting you! Need an answer ASAP. Genius people at fossils where u at

Explanation:

It should be in this order from oldest to youngest: 2,1,5,7,9,3,4,8,6.

Since we know 2 is the oldest and once each organism goes extinct it stops being in any samples, we can start at 2 and go through the samples to see where that fossil shows up again and when we find the next sample its in, we pay attention to any new fossils that show up and move onto the next sample with the second fossil in it and so on.

when atoms of different types of elements join together, they make molecules called compounds. water consists of compound molecules made up of 2 hydrogen atoms and 1 oxygen atom. this is why it's called h2o. water will always have 2 times the number of hydrogen atoms as oxygen atoms.

i think it is dna, i'm not totally sure but i think it might be.
