Predict what would happen to a neuron's resting membrane potential if the number of sodium ion channels increased. the membrane potential would become more positive. the membrane potential would remain the same due to the activity of the sodium-potassium pump. the membrane potential would become more negative. the membrane potential would become slightly more negative.

The answer is the membrane potential would remain the same due to the activity of the sodium-potassium pump.  When a nerve or muscle cell is at "rest", its membrane prospective is called the resting membrane potential. In a representative neuron, this is about –70 millivolts (mV). The minus sign specifies that the confidential of the cell is negative with respect to the neighboring extracellular fluid.

the transfer of energy between two molecules spaced just nanometers apart plays a key role in many technologies, including photovoltaics, quantum information systems, lighting, and sensors, as well as in biophysics to measure nanometer distances and in photosynthesis. but an open question in this area is what effect, if any, the surrounding photonic environment has on this nanoscale energy transfer. by designing and performing a carefully controlled experiment to answer this question, scientists have settled the debate and found clues to improving the efficiency of many of the technologies that rely on this process.
