Answer:
Explanation:
Antibiotics are chemical agents that are used to treat bacterial infections. ... Vaccines are used to prevent infection, particularly viral infections.
Subatomic particles include electrons, the negatively charged, almost massless particles that nevertheless account for most of the size of the atom, and they include the heavier building blocks of the small but very dense nucleus of the atom, the positively charged protons and the electrically neutral neutrons.
And I don't see any of the particles. so I can only answer the first one.
Hydrogen bonding is important in many chemical processes. Hydrogen bonding is responsible for water's unique solvent capabilities. Hydrogen bonds hold complementary strands of DNA together, and they are responsible for determining the three-dimensional structure of folded proteins including enzymes and antibodies

Answer:
The aromatic ringsare the number 1 and 2.
Identify which lone pairs are participating in resonance (in aromatic rings).
- One lone pair on the sulfur atom.
Explanation:
For a compound to be aromatic it has to comply with Hückel's Rule, which says that the quantity of electrons in the pi orbitals, has to be a multiple of
4n + 2
for n = 0, 1, 2, 3.
