A typical red blood cell contains about 270 million hemoglobin molecules. If one red blood cell bound the maximum amount of O2 as it passed through the lungs, how many molecules of oxygen could it theoretically carry to the tissues?

The diagram illustrates the activity of vesicles during a cellular process.

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.
