Why is it important for scientists to review and repeat the work of other scientists? 1.a scientific theory must be tested three times before it is proven. 2.the scientific method only applies to repeated experiments. 3.an experiment may have had errors that the scientists didn't recognize. 4.the results of individual scientists may be influenced by bias. 5.an experiment must be performed twice before the data can be analyzed.

Individuals within populations exhibit some diversity. as a result of possessing slightly different traits, some individuals are better able to survive and reproduce than others. if these individuals changes in the characteristics of the population may occur over time. the cumulative change in these characteristics is known as
