2. If a mutation occurs in one member of a population, does that constitute evolution? 1.Yes. Any change in an individual always results in evolution of the entire population. 2.Yes. Mutations always encode for favorable traits. 3.No. Mutations always lead to death. 4.No. Evolution is a product of change in the population, not in the individual.

8. What is the difference between a theory and hypothesis? 1.A theory is widely supported by scientific evidence; a hypothesis is an educated guess that can be disproved. 2.A hypothesis cannot be disproved; a theory is an educated guess. 3.A theory is true; a hypothesis is false. 4.A hypothesis is true; a theory is false.
