To apply parsimony to constructing a phylogenetic tree, To apply parsimony to constructing a phylogenetic tree, choose the tree that assumes all evolutionary changes are equally probable. choose the tree that represents the fewest evolutionary changes in either DNA sequences or morphology. choose the tree in which the branch points are based on as many shared derived characters as possible. base phylogenetic trees only on the fossil record, as this provides the simplest explanation for evolution. choose the tree with the fewest branch points.

Now it's your turn to investigate human impact around the world. grab your virtual lab coat and put on your environmental science hat. you will be taking a trip around the globe to explore three locations. at each location, you will investigate the cause and effect relationships of deforestation, desertification, and urbanization. you will also gather evidence of how these factors have impacted the environment over time

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.
