The outcome of a toxin that results in creating the same length of the refractory period in cardiac muscles as present in the skeletal muscles. Introduction: The heart muscles generate an action potential due to the depolarization of the sinoatrial node (SA node) of the heart, which acts as a natural pacemaker. The action potential leads to muscular contraction, which helps the heart to supply blood to the whole body. The other cells that have the capability to generate an action potential as a result of the depolarization are the skeletal muscle cells and the neuron cells. After one action potential is generated, the cell becomes resistant to generating another action potential for a few seconds. This period is termed as the refractory period.

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.
