Why isn't evolution a "law" in science?
Because there are other explanations; it doesn't fit for 100% of the concepts.
A younger rock has more of which element?
Potassium
What are the two types of fossils?
Body - direct evidence
Trace - indirect evidence
What does biodiversity mean?
Many different living things.
What is the difference between biological evolution and chemical evolution?
Biological - changes in life
Chemical - origin of life
What is the Law of Superposition, and what type of rock dating does it support?
Younger layers on top of older layers; relative dating.
Why is the fossil record said to be "incomplete?"
Because some things don't fossilize well, and are missing from the timeline.
What are the 5 kingdoms of living things?
Monera (bacteria), protists, animals, fungi, plants
Why can't animals "try" to adapt to a new environment?

What are two of the three organic molecules that Miller and Urey started with in their experiment?

What causes different areas of the world to have different rock strata?
Erosion, weathering, mountain formation, etc.
Why is there a time gap between Earth's formation and fossils?
It took the Earth over a billion years to be habitable to biomolecules.
Which characteristic of living things category would having green eyes fit into?
Reproduction (heredity)
Pangea - supercontinent - shows connected fossil remnants.
Around 15% (85% Argon)
What is the difference between a mass extinction and adaptive radiation?
Mass extinction - decrease in biodiversity (gone!)
Adaptive radiation - increase in biodiversity (new!)
What is biotechnology and how is it connected to something we've learned?
How biology creates the need for new tech, and tech helps with discoveries in bio.
