What is the function of the sodium potassium pump in nerve cells? It acts to transport sodium and potassium ions across the cell membrane in a ratio of 3 sodium ions out for every 2 potassium ions brought in. In the process, the pump helps to stabilize membrane potential, and thus is essential in creating […]
Why do compasses not point south?
Why do compasses not point south? A magnetic compass does not point to the geographic north pole. A magnetic compass points to the earth’s magnetic poles, which are not the same as earth’s geographic poles. This fact means that the north end of a magnet in a compass is attracted to the south magnetic pole, […]
Is there a place with no natural disasters?
Is there a place with no natural disasters? Bahrain. Bahrain is often ranked as one of the safest places due to the low frequency of natural disasters and government security. It is a small monarchy in the Persian Gulf. Other than dust storms and hot summer, there is not much danger from extreme natural disasters. […]
Is the crust the least dense layer?
Why are particles deflected bounced backwards?
Why are particles deflected bounced backwards? A tiny number of alpha particles, traveling at 10% of the speed of light, hit a dense atomic center right in its middle. The collision and the repulsion cause the alpha particle to “bounce” backwards and move on a very different path. These are the reflected rays. What did […]
Will carbon monoxide alarm keep going off?
What is the fastest way to restore refrigerant?
What is the fastest way to restore refrigerant? In extreme ambient temperatures, submerging the recovery cylinder in ice or ice water is the most effective way to keep a cylinder cool. A well-cooled cylinder ensures a fast recovery process. It is important to note that rapid heat buildup can be an indication of non-condensable gases. […]
Why evaporation takes place at all temperatures?
Why evaporation takes place at all temperatures? Explanation: Evaporation takes place at all temperatures. The air molecules that strike the surface impart some energy to the water molecules. If this energy is sufficient enough to change the phase of the water molecules, we experience a phenomenon known as evaporation. At what temperature does water evaporate? […]
Why do we use two regression equations?
Why do we use two regression equations? In regression analysis, there are usually two regression lines to show the average relationship between X and Y variables. It means that if there are two variables X and Y, then one line represents regression of Y upon x and the other shows the regression of x upon […]
What is the most important factor for the formation of our planets?
What is the most important factor for the formation of our planets? Gravity pulled matter into the center core, nuclear fusion began, and our Sun was created. Remaining matter and gas clumped together to form the planets. What evidence is there for the nebular theory? What Evidence do we have of a Nebular Theory-type development? […]
