The answer is nitrogen. It comprises approximately 78% of the atmospheric air. Nitrogen can be found in most life processes including as a component of amino acids –amino group (NH3-). It is also involved in the structure of nucleosides that are critical in the formation of nucleotides and ATP.

The phrase "main component of atmospheric air" already points to nitrogen as it makes up 78% (mole basis) of atmospheric air. Nitrogen is the main element found in amino acids (amino group refers to NH3) and amino acids make up almost all important life molecules such as proteins, DNA, and ATP.

Which ion most readily leaks across a neuron's membrane, helping to establish the resting potential? Which ion most readily leak
EastWind [94]

Answer:

K+

Explanation:

Leak channels are the gated channels that randomly open and close. The plasma membranes have many more potassium ion (K+) leak channels than the leak channels for other ions such as sodium ion. Also, the potassium ion leak channels are leakier than the sodium leak channels and allow exit of more and more K+ from the neurons. This makes the inside the neuron negative at rest and outside becomes more positive. In this way, the leakage of K+ across the K+ leak channels is mainly responsible for maintaining the resting potential.

yuradex [85]
The energy from sunlight comes in the form of photons, and this energy is used in the light dependent reactions of photosynthesis. The first function carried out by the photons in energizing electrons in the chlorophyll. The energized electron travels through the electron transport chain and subsequent steps are carried out to utilize this energy to form ATP.

Rick’s class plans to study the effect of eating different breakfast foods on grades in morning classes. Students in the class w
Alborosie
<span>Some of the things that would make the experiment invalid would be, if there was a variation in the behavior of the class with respect to food - for example, if some people ate their breakfast earlier than the others. This then would mean that some students would have already digested their breakfast during the morning classes and the others would still be digesting. </span>
