tetrodotoxin binds to sodium channels and blocks the passage of sodium ions. based on this information, which symptom would most likely occur in an organism exposed to tetodotoxin?

a.
decreased appetite due to the production of hormones that indicate fullness
b.
paralysis due to lack of action potentials to signal muscle tissue
c.
increased heart rate due to increased nerve impulses to the heart muscles
d.
blindness due to proteins in the eyes denaturing and losing functionality

What best explains whether bromine (br) or neon (ne) is more likely to form a covalent bond? bromine forms covalent bonds because it has seven valence electrons, but neon has eight valence electrons and already fulfills the octet rule. bromine forms covalent bonds because it has many electron shells, but neon has only two electron shells and is tightly bound to its electrons. neon forms covalent bonds because it can share its valence electrons, but bromine has seven valence electrons and can gain only one more electron. neon forms covalent bonds because it has only two electron shells, but bromine has many electron shells and will lose electrons in order to fulfill the octet rule.
