The way in which the resting membrane potential is established and maintained in neurons. Concept introduction: When a neuron does not respond to the impulses or signals of other neurons, the neuron is said to be at resting potential. In the resting phase, the voltage-gated ion channels open to facilitate the movement of sodium and potassium ions across the membrane. When the neuron is at rest, more sodium ions are accumulated outside the cell membrane than the potassium ions inside the cell membrane. As a result, the cytosol is relatively negative than the interstitial fluid (IF) outside of the cell. This unequal distribution of positive and negative charge across the cell membrane is known as resting membrane potential (RMP).

Luke recently moved to a new apartment and wants to grow houseplants but isn't sure which room will be the best fit for them. Apply your knowledge of the scientific method to recommend a strategy for Luke to follow when determining the ideal location for houseplants in his new apartment.

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. Describe the data that would be recorded in each of the…
