What do the following areas of scientific understanding have in common? 1. the understanding of the structure of the Solar System
2. the understanding of how traits are passed from parents to offspring
3. the understanding of the building blocks of matter and life
A. The scientific knowledge related to these areas has changed over time.
B. There is no scientific knowledge related to these areas of science.
C. We know all there is to know about these areas of science.
D. The scientific knowledge related to these areas has remained unchanged since their discovery.

C

Explanation:

because we know a lot about the different things in the solar system and much more

relative dating involves things like higher layers are most recent than rocks lower in the sequence. this can be extended to the known sequence of fossils. rocks containing rabbit fossils are later than those containing dinosaur fossils.  

absolute dating methods mainly use radioactive elements that have known rates of decay and produce recognizable products. for example potassium 40 decays to produce argon. once a rock has solidified the argon is trapped. by measuring the argon and potassium0 you can get an accurate number for the age.  

some other methods are good for archaeological ages. dendrochronology involves recognizing the sequence of tree rings. the orientation of magnetized particles in baked clay can be used to date a fire.
