N_3  is more basic than N_1 in imidazole.

Imidazole have two nitrogen attached in the ring at N_1 and  N_3 .

This compound is an aromatic compound as it have (4n+2)π electrons which means lone pair electrons of N_1 nitrogen atom also takes part in π

system.

Thus when a proton attacks on this compound it easily attacks at N_3 rather than N_1.

After the attack of H^{+} ion at N_3 the conjugate base thus formed is also aromatic and hence is more stable.

If the proton had attacked at N_1 the conjugate base would not be aromatic and its stability will decrease.

The reaction is shown in the image attached

sveticcg [70]
<span>The answer is lactic acid/lactate. This is caused by anaerobic respiration in muscles especially during strenuous physical activity due to low oxygen supply to muscles in respect to the demand. When there is sufficient oxygen in the muscles, pyruvate is broken down aerobically in the Kreb’s cycle. However, it is converted to lactate in the anaerobic pathway. Lactic-acidosis occurs when lactic acid accumulates in tissues and slows down metabolic pathways</span>

Afina-wow [57]
The answer is all of them. But in a school situation, A would be appropriate. This is because the smoke gets into the smokers lungs, whether it be marijuana or tobacco, and can cause cancer cells to grow in your lungs and enter your bloodstream.
So A is the answer.
