2. Individual organisms can evolve.

 About 9,000 years ago people generated a new plant species, Zea mays (maize/corn), through the domestication of a grass known as teosinte.

(12 pts) Cells Short Answer Section: The figure below represents an animal cell OR a plant cell OR a bacterial cell (exactly one of these!).  You need to know which one it is to answer all of the questions correctly.  Right answers for the wrong cell type won’t count.  ALL the matching questions should be answered with this same cell type in mind. Match the letters labeling components in the cell diagram, and boxes in the concept map below the cell diagram, to the appropriate answer choice.

Science favors the parsimonious explanation, meaning the explanation that is the
