Please offer your explanation to the following questions:
a. What are the approximate size of a cell, a molecule, and an atom?
b. What is the difference between the functionalized carbon we used for water filtration and bulk carbon, e.g. the lead in your pencil?
c. Why do you have to wait 48 hours to see the bacteria on the petri dish?
d. Where does the waste water from your house go?
