Force, Motion, and Energy
What is the formula for speed?
S = Distance / Time
Why do hot air balloons rise?
convection - hot air rises above cooler air
What kingdom is a prokaryotic extremophile?
Archaebacteria
Eutrophication --> Dead Zone
What is the process by which organisms with variations that help them survive in their environment live longer, compete better, and reproduce more than those that do not have the variations?
natural selection
What is the difference between speed and velocity?
Speed is not a vector; it only has magnitude. Velocity is a vector quantity that includes both magnitude and direction.

Advantage: Only one parent, faster, more offspring
Disadvantage: No genetic variation
A company cuts down and paves over a small forest to build a shopping mall and a large parking lot. Why would this have a negative effect on water systems?
Concrete is not permeable, which decreases percolation and increases runoff.
What percentage of energy will a secondary consumer have if an autotroph has 100% of energy?
1%
