Why is ozone important in the atmosphere?
Protects organisms from the majority of UV rays
300

400
What is the difference between organic chemistry and inorganic chemistry?
Organic chemistry refers to matter with carbon-containing chemicals while inorganic chemistry refers to matter that does not contain carbon
400

What are graduated cylinders
400
When talking about the human body, what is the largest organ?
What is skin.
500
What is the chemical formula for ozone and how does it form?
What is O3. UV rays break apart O2 molecules into single atoms, which then bond with other O2 molecules form 3 of them
500
Why is studying the world at a submicroscopic level important?
You must understand the properties of atoms before you can begin studying the interactions that occur on a larger level
500
What are the two types of research and what is the difference between them?
Pure research is done to gain knowledge while applied research is done to solve a problem
