What are the basic building blocks of all things?
@JackofallTradez
Depends on what things you are talking about. I'd say atoms as a general answer.
Cells
If you are talking about organisms
its atoms.. thank you :)
⦁ Define the two ways scientists are able to date fossils?

absolute dating and relative dating. absolute dating is by using radioisotope decay rates and relative dating is by using stratigraphy and reference fossils (that is where your fossil is in the layers of sediment and what else is in there with them).
Each type of radioisotope decays at a standard rate (called a half-life) and you can tell how old a fossil is by comparing the amount of radioisotope still present in the fossil compared with the amount of the product of its decay.
