Why is it central to the field of biology?1. Evolution = genetic changes + time2. It is the process of change, It is a result of gene changes over time. "Descent with modification"● What are the steps of the process of science?1. Make Observations, Ask Questions2. Form Hypothesis, Make Prediction3. Conduct Testing, Experiments4. Examine Results, Make Conclusions● Why are controlled experiments necessary?1. A good experiment must have a control. Without a control, data is null. With a control, confounds are avoided. ● What is a hypothesis? Practice forming a hypothesis statement.1. A statement and prediction of an experiment's results. If____, then____. ● What is the difference between a hypothesis and a theory?1. A hypothesis can be incorrect. 2. A theory must:■ Be broader than a hypothesis■ Have a Large body of evidence■ Multiple lines of Testing■ Be Peer
