Hunting reduced the population size of the northern elephant seal to as few as 20 individuals at the end of the 19th century. Their
population has since rebounded to over 30,000, but they have much less genetic variation than a population of southern elephant
seals that was not so intensely hunted. How is the lack of genetic variation related to the hunting episodes of the 1800's?
Genetic drift occurred; the few individuals left behind were the seals that
passed on that specific gene pool
Adaptation occurred; some seals were able to adapt to the hunting
environment and they survived to pass on their genes.
During the 1800's some northern seals migrated and were able to survive

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.
