1) 25% (1/4 of the predictions are cc)
2) cc (both lowercase)
I think the correct answer from the choices listed above is option A. The conclusion that the fossil record support is that species have changed over time. It supports the theory of evolution rather than the creation. Hope this answers the question.
The mass is made up of protons and neutrons, the valence electrons only determine stability, not mass
Answer:
Using the concept of relative dating
Explanation:
Scientists use the concept of relative dating principles to determine when the Great Oxidation event occurred.
Relative dating is the process of placing ancient event in their proper time sequence based on the relationship between rock lithologies.
- An event like the great oxidation will have significant chemical, biological and physical effect on the rock units.
- Rocks that form during this period in time will have very unique chemical signatures.
- Therefore, by studying these rocks, the age of the layer can be fixed when we compare it to the standard geological column.
