Quiz 1 Unit 2

What are the three domains of life?

Bacteria, Archaea, and Eukarya

Which is the best characteristic that distinguishes the kingdom Archaebacteria from the kingdom Eubacteria?

Cell Wall Structure

An organism has the following characteristics: cell wall, autotrophic, unicellular, and eukaryotic. What kingdom does it most likely belong in?

Protista

Which kingdom(s) include organisms that are autotrophic or heterotrophic?

Protista and Eubacteria

Why do classification systems change over time?

Scientists find new evidence in their studies.

Which level of taxonomy has the fewest organisms?

Species

Mike is studying the phylogenetic tree for big cats. He made several statements about the tree. Which statement is not true?

The leopard is more closely related to the tiger than to the snow leopard.

Phytoplankton, are microscopic organisms that can be found in freshwater and salt water environments. They perform photosynthesis to get energy and act as an important food source for larger organisms, such as the whale. Which characteristic describes the phytoplankton but not the whale?

The phytoplankton is unicellular.

Which characteristics are used to differentiate among the six kingdoms?

body type, cell type, cell structure, nutrition

Consider these phylogenetic trees. The first tree is based on physical characteristics. The second tree is based on structure, genetics, and evolutionary history. Which can be concluded from a comparison of the two phylogenetic trees?

2. Classification can change with new discoveries and evidence.

Which kingdom is known to contain organisms that have cells with no cell walls?

Animalia

What are the six kingdoms of life?

Archaebacteria, Eubacteria, Animalia, Protista, Fungi, Plantae

The species that is known as a robin in England has a yellow breast, and another species that is known as a robin in the United States has a red breast. Which statement about common names does this fact best exemplify?

Different species can share the same common name.

Which taxonomic group includes kingdoms and all other levels of taxonomy?

Domain

The classification levels of a human are listed below from largest to smallest. Eukarya Animalia Chordata Mammalia Primates Hominidae Homo sapiens Which level of biological classification do Sapiens and Eukarya represent, respectively?

Domain and Species

Which level of classification includes the least species? (other than species)

Genus

Consider the classification levels of a honey bee. Eukarya Animalia Arthropoda Insecta Hymenoptera Apidae Apismellifera To which class do honey bees belong?

Insecta

Which kingdom is made up of mostly, but not exclusively, unicellular organisms?

ProtistA

Which is the best definition of a phylogenetic tree?

a branching chart that depicts evolutionary relationship among organisms

What is binomial nomenclature?

a two word system for naming organisms by using the genus and species

Which two organisms are most closely related, based on the tree above?

dinosaurs and birds

Which can modern taxonomy do?

distinguish how closely related organisms are

Which series correctly lists the eight taxonomic levels in order, from the broadest group to the most specific group?

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

Which scientific area has the most influence in shaping modern classification methods?

evolution

Which type of evidence is least likely to result in changes to a phylogenetic tree?

physical characteristics
