the structure of sticks and balls refers to an organic radical, called EThyL.
Explanation:
Ethyl has three main carbons, of which three hydrogen molecules come from the first carbon, two from the second, and three other hydrogen molecules from the third.
The amount of hydrogens to which a carbon can be attached, which according to an organic structure depends on the amount of carbons to which the carbon is attached, a carbon must never exceed 4 bonds.

Somatosensory is made of a group of receptors that sense many things. One of them is proprioception, the condition of the body and its movement.</span>
Answer: C.
Chemoautotrophic bacteria fix atmospheric nitrogen
Explanation:
Nitrogen-fixing bacteria, microorganisms capable of transforming atmospheric nitrogen into fixed nitrogen (inorganic compounds usable by plants). More than 90 percent of all nitrogen fixation is effected by these organisms, which thus play an important role in the nitrogen cycle.
Bacteria play a central role: Nitrogen-fixing bacteria, which convert atmospheric nitrogen to nitrates. Bacteria of decay, which convert decaying nitrogen waste to ammonia. Nitrifying bacteria, which convert ammonia to nitrates/nitrites.
