5.
Which statement is an example of deductive reasoning?
  1. Most swimming animals use fins; therefore, fins are an adaptation to swimming.
  2. Mitochondria are inherited from the mother; therefore, maternally inherited traits are encoded by mitochondrial DNA.
  3. Small animals lose more heat than larger animals. One would not expect to find wild mice in the North and South Poles.
