Hi, I'm in connexus and the answers are correct Thank you!
Question 8: How is a mold and cast related (My answer):
The mold and cast are related because the mold is the object that makes the shape of the cast and they both hold shape or are part of an organism (If anyone needs me to explain how they're part of an organism lmk)
Question 9: If the following graph represents the decay of strontium-90in an igneous rock what event occurred at 0 years on the horizontal axis?
The event that occurred was metamorphic of igneous rock aka formation of igneous rocks from melted magma
Question 10: Suppose you found a fossil of a clamshell, what can you conclude about the once-living organism and how it became a fossil? (My answer):
since the fossil is a clam shell it must have lived in water so after it died over time the clam shell got buried in sediment and became a fossil
hope this helps, not saying these are right, this is just what I concluded
Here et me do the test and give you the answers! Dont worry they will be right trust me!! Oh and by the way I am a girl!!

8,9, and 10 : do it by yourself
Since this is not my area of expertise, I searched Google under the key words "earth's early atmosphere gases percentages" to get these possible sources:
https://www.google.com/search?client=safari&rls=en&ei=hreaW5DbN9mT0PEP2_CU-Aw&q=earth%27s+early+atmosphere+gases+percentages&oq=Earth%27s+earliest+atmosphere&gs_l=psy-ab.1.0.0i71l8.0.0..154980...0.0..0.0.0.......0......gws-wiz.mnPvqDY5A4M
In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search. Also see http://hanlib.sou.edu/searchtools/.
