Definition
A newly discovered species can be classified as a member of the bacteria if only in bacteria. the same logic applies to classifying a new species in the Archaea or Eukaraya. |

Term
Explain the relationship between a hypothesis and a prediction and why experiments are convincing ways to test predictions. |
|
Definition
A hypothesis is an explanation of how the owrld works: a prediction is an outcome you should observe if the hypothesis is correct.
Experiements are convincing because they measure predictions form two opposing hypotheses. Both predicted actions cNNOT OCCUR, SO ONE HYPOTHESIS WILL BE SUPPORTED WHILE THE OTHER WILL NOT |
