400
These three elements are found in all organic macromolecules.
What are carbon, hydrogen, and oxygen?
400
The ability for water to maintain a relatively stable temperature unless energy is applied.
What is high heat capacity?
400
Surrounds and protects the DNA from damage.
What is the nucleus?
400
Constructs channels through the cell membrane for the passage of large compounds and water.
What are proteins?
500
Over generations, organisms change to best adapt to their environment.

500
The central element needed to be classified as "organic".
What is carbon?
500
Measurement of the hydrogen ion concentration in a solution.
