Whether the generation of inhibitory postsynaptic potentials (IPSPs) make it more likely or less likely that an action potential (a nerve signal) will be sent. Concept introduction: Postsynaptic potentials are graded potentials that occur in postsynaptic neurons. It is the temporary change in the electrical polarization of the membrane of a neuron. When the neuron is hyperpolarized, postsynaptic potentials are called IPSPs. The binding of neurotransmitter to the receptors on the postsynaptic membrane changes the permeability and membrane potential of the postsynaptic neuron. This results in a difference in the electrical charge between the inside and outside of the membrane. The action potential is generated after the establishment of membrane potential, and the nerve impulse flows throughout the neuron.

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…
