Question

1. Describe how a biologist's research can proceed from an idea to a published article.

2. State why an observation cannot be an inference

3. Indicate the differences in the ways that data can be collected in biological research.

4. Differentiate between independent variables and dependent variables.

Answer 1

4. The independent variable is the variable that you alter in an experiment; you will want to investigate the effect that changing the independent variable has on the dependent variable. The dependent variable is the one that you measure. For example, in measuring the effect of light intensity on rate of photosynthesis, the light intensity is the independent variable and the rate is the dependent variable.
