For a neuron with an initial membrane potential at -70 mV, an increase in the movement of potassium ions out of that neuron's cytoplasm would result in the

The given condition of an increase in the movement of potassium ions out of that neuron's cytoplasm would result in the hyperpolarization of the neuron.

Hyperpolarization is a change in a cell's membrane potential becomes more negative at a particular spot on the neuron's membrane

A hyperpolarization is an event or stage that takes place when some potassium channels remain open and sodium channels reset.The sodium-potassium pump keeps the concentrations of Na+ and K+ at constant disequilibrium to set the membrane potential of neurons.Increased potassium movement leads to more potassium ions out of that neuron's cytoplasm. It can be seen as a slight dip following the spike.

Thus, the correct answer would be the hyperpolarization of the neuron.

The potassium ions are positively charged(cations) if the charge is -70mV the outflow of cations will cause a decrease in the potential. The potential will become lower than -70mV.

Iwould say overuse ( but not 100% sure ) in the u.s. we tend to overuse water by leaving it running, throwing it away, taking long showers, etc.

Ican not answer this question since it does not have enough information
