Evolution Correct Answer-Change in the inherited traits in a population of
organisms over time.
Ecology Correct Answer-How organisms interact with each other and the
environment
Natural selection Correct Answer-A natural process resulting in the evolution
of organisms best adapted to the environment.
Theory of evolution Correct Answer-Created by Charles Darwin, organisms
pass on their DNA to their offspring; avoiding close relatives for more variety.
Microeveolution Correct Answer-The change in the inherited traits in a
population of organisms within a single species over time (ie. bacteria gaining
the ability to withstand/resist antibiotics and survive)
Macroevolution Correct Answer-Production of new species via thousands-to-
millions of years of microevolution (ie Finches in the Galapagos have different
beaks depending on the bird's respective needs for survival).
Artificial selection Correct Answer-Selection by humans for breeding of
useful traits from the natural variation among different organisms (ie. dog
breeds)
Prokaryotic cell Correct Answer-A type of cell lacking a membrane-enclosed
nucleus and membrane-enclosed organelles; found only in the domains Bacteria
and Archaea.

membrane
Carbohydrates Correct Answer-Connected to the protein found in the cell
membrane, they help with cell communication
Centrioles Correct Answer-Cell organelle that aids in cell division in animal
cells only
Mitochondria Correct Answer-Powerhouse of the cell
