Activation of a G protein would NOT be considered signal amplification because it: a. is part of a receptor-ligand complex and diffuses to activate a single target, such as adenylyl cyclase.
b. triggers the release of intracellular ions.
c. diffuses to activate a single target, such as adenylyl cyclase.
d. is part of a receptor-ligand complex.
e. is part of a receptor-ligand complex and triggers the release of intracellular ions.

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.
