Spinal curvatures, their formation, and functions. Concept introduction: The vertebral column is not straight and has some flexibility. There are four spinal curvatures in the vertebral column. These curvatures include the sacral curvature, lumbar curvature, cervical curvature, and thoracic curvature. Among these curvatures, sacral and thoracic are primary curves; while lumbar and cervical are secondary curves.

A farmer has noticed that his soybean plants produce more beans in some years than others. He claims to always apply the same amount of fertilizer to the plants, but he suspects the difference in crop yield may have something to do with the amount of water the crops receive. The farmer has observed that the soybeans on his farm usually receive between 0 to 0.5 inches of water per day, but he is unsure of the optimal average daily amount of water with which to irrigate. 1. State a question that addresses the farmer’s problem 2. Conduct online research on “soybean crop irrigation" and record a brief summary of the findings 3. Construct a testable hypothesis and record i 4. Design an experiment to test the hypothesis and describe the procedures, variables, and data to be collected 5. What is the purpose of a control group in an experiment? What would the control groups be for each of your designed experiments in this exercise? 6.
