<span>The correct answer is b. Option a is incorrect because these models can demonstrate scientific theories, but they don't prove scientific theories (you would need experiments for that). Option c is incorrect because the models aren't always representing something abstract (i.e. DNA is very real, just very small). Option d is incorrect because they don't precisely mimic something in nature, but instead help us visualize something in nature that is difficult to see or comprehend.</span>
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.
Answer:
"scattering" that would be the correct answer :)

Answer:
Ratio of students to chaperones = 20 / 7
Explanation:
Given:
Total student = 100
Total chaperones = 35
Find:
Ratio of students to chaperones
Computation:
Ratio of students to chaperones = 100 / 35
Ratio of students to chaperones = 20 / 7
You need to know 1) How much kinetic energy it absorbed before it broke.
2) What materials are able to scratch it.
3) Its mass.
