Classification

Which of these pairs of organisms are found in the same domain?

• plants and archaea

• bacteria and protists

• protists and fungi

• bacteria and archaea

Organisms classified as fungi have unique characteristics. Which of the following

characteristics are found only in organisms classified in the kingdom fungi.

• single cells without a nucleus

• multicellular with chloroplasts

• multicellular and externally absorbs nutrients

• colonies of single, photosynthetic cells that reproduce asexually

The list below describes an organism.

- Unicellular

- Prokaryotic

- Lives in very harsh environments

- Lacks peptidoglycan

Based on this list, in which kingdom should the organism be classified?

• Eubacteria

• Protista

• Archaebacteria

• Animalia

According to the cladogram, which of the following organisms have fur?

• Sun Bear

• Giant Panda

• Raccoon

• Dog

The Florida panther was once considered to be a subspecies of cougars. Current scientists, however, have studied the Florida panther and removed the subspecies classification. Which of the following would explain why the classification of the Florida panther changed?

• New genetic evidence suggests a much closer relationship between the Florida panther

  and other cougars.

• Advanced technologies have shown a large difference in cell structure between the

  Florida panther and other cougars

• Study of their embryos shows major differences in the development of the Florida panther

  fetus when compared to other cougars

• Shared physiological features between the Florida panther and other cougars were also

  found in newly discovered organisms in the world

The figure below demonstrates the changes to our understanding of the scientific taxonomy for living organisms.

As technology became more advanced, what happened to the classification system?

• Advances in DNA sequencing have eliminated the original kingdoms from the Linnaean

  system.

• Advances in the microscope have allowed us to move from the six kingdom system to a

  three kingdom system.

• Advances in the microscope have allowed us to modify our classification system, and

  create the kingdom animalia.

• Advances in DNA sequencing have allowed us to modify our classification systems over

  time to include six kingdoms.

The diagram below represents possible evolutionary pathways of certain organisms.

Which species is most closely related to species L?

• species F

• species G

• species I

• species E

The image shows an insect called a Walnut Twig Beetle. Without a microscope, you

would not be able to see the hair like structures and texture of the beetle's exoskeleton.

Which microscope would have been used to take the image of the beetle?

• dissecting microscope

• compound microscope

• scanning electron microscope

• transmission electron microscope
