Which of the following scenarios represents a density independent limit on population?
Porcupine population growth is limited by the spread of disease
Box turtle population growth is regulated by a hurricane that destroys their
nests
Woodpecker population growth is regulated by opossum predation of
woodpecker eggs
Caribou population growth is limited as a result of grass depletion

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.
