Nitrogen, even though makes for about 78% of our atmosphere, and is by far the most abundant gas in it, we can not use it because it can not be taken out of the atmosphere as it is. If we take nitrogen in the form as it is in the atmosphere it is useless for both humans and plants. It has to go through a process of ''fixation'' first before we can actually use it in our food.

Answer:
option B) is correct
Explanation:
The all or none response means that if a muscle contracts, it will contract completely. Thus implying the all or none law which states:
The potential of a response of a muscle fiber or nerve cell is independent of the potential of the stimulus. If a stimulus is more than a certain critical value it will trigger muscle fiber or a nerve. Most importantly resulting in either an all-or-none response thus reducing possibility of any information loss.
