Lecture 2 Phylogenetics

Which of the following places the taxonomic levels in order from most inclusive to most specific.

• domain, kingdom, phylum, class, order, family, genus, and species

• species, genus, family, order, class, phylum, kingdom, and domain

• kingdom, phylum, class, order, family, genus, and species

• domain, kingdom, family, class, order, phylum, genus, and species

The two taxa that are included in the binomial nomenclature (scientific name) of a species are:

• genus and species

• family and species

• family and class

• order and genus

The name for this type of graphical representation of species relationships is a

• species tree

• phylogenetic tree

• evolutionary tree

• tree of life

Phylogenetic trees only represent relationships at the community level of organization.

• true

• false

Positions on phylogentic trees indicate closeness or distance of relationships.

• true

• false

It is a system of organizing things based on shared characteristics.

• Taxonomy

• Systematics

• Phylogenetics

• Classification

What is the primary purpose of a phylogenetic tree?

• To depict geographical distribution of species

• To illustrate food webs in ecosystems

• To classify organisms based on habitat

• To show the evolutionary history of species

Which of the following is NOT component in electron transport chain?

• Cytochrome

• Flavoprotein

• Cytochrome c

• ATP synthase

As electrons travel down the electron transport chain, they release

• ADP

• Energy

• ATP

• Hydrogen ion

The effect of increased levels of hydrogen ions in the intermembrane space of the mitochondria is

• Increase ATP production

• Decreased levels of oxidative phosphorylation

• Increased levels of water in intermembrane space

• Decreased levels of chemiosmosis
