(5)extinction is least likely in which of the following scenarios?
a) a population of rabbits exhibiting little genetic variation.
b) a large field filled with the same species of wheat.
c) a pond ecosystem with a lot of biodiversity.
d) an ecosystem that exists in an unstable environment.

As soon as possible this assignment is due in 5 minutes atoms in a molecule are bonded together by sharing, gaining, or a. photons b. protons c. neutrons d. energy f. electrons

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.

What happens as electrons move along the chain of molecules known as the electron transport chain? they gain energy, which causes atp molecules to lose phosphate groups. they gain energy, which causes h *ions to join with oxygen to produce water. they lose energy, which is then used by the cell to make atp. they lose energy, which is then used to break down atp.
