Neurons - CORRECT ANSWER - Cells that make up all nervous tissue in the human body
Neutrons - CORRECT ANSWER - Neutral particles in the nucleus of an atom
Deductive Inquiry - CORRECT ANSWER - Testing general assumptions to specific elements
Inductive Inquiry - CORRECT ANSWER - Scientific method: reasoning in which the
premises are viewed as supplying strong evidence for the truth of the conclusion
Wavelength - CORRECT ANSWER - The distance from the highest point of one wave to the
highest point on the next wave (distance from crest to crest)
Frequency - CORRECT ANSWER - How many waves pass a given point in a second
Amplitude - CORRECT ANSWER - The height of the wave above the level line
Carbon - CORRECT ANSWER - The element that makes up the backbone of all organic
molecules
,"Matter and energy" - CORRECT ANSWER - Include solar energy, physical and chemical
properties, and machines
