Which of the following describes the most likely change to terrestrial biomes resulting from warmer average global temperatures?
a deciduous trees found in temperate seasonal forests would flower later in the year.
b the latitude range of tropical rain forests would narrow closer to the equator.
c high-latitude biomes, such as the tundra, would experience a decrease in net primary productivity.
d. the global distribution of midlatitude biomes, such as grasslands and temperate rain forests, would increase.

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.
