Question 1

For which of the following would the biological species concept work best in determining whether an organism or population of organisms is a distinct species? A complete set of bones of a dinosaur is recovered. A migratory herd of a caribou mixes with a second migratory herd of caribou. A population of frogs is separated by a high mountain range from a population of similar-looking frogs. The organisms in a bacterial population reproduce by cell division. A population of plants mostly reproduces asexually by sending new shoots up from underground structures.

Accepted Answer

A migratory herd of a caribou mixes with a second migratory herd of caribou.

Question 2

Analyzing DNA sequences or the proteins that genes make allows taxonomists to draw conclusions about the degree of relatedness between different organisms. Which of the following statements is true ? DNA analysis suggests that the turkey vulture is more closely related to crows and ravens than to vultures of Asia and Africa. DNA analysis suggests that what was considered one species of African elephant is in fact two species. Protein analysis suggests that the guinea pig is more closely related to pigs than to rodents. Protein analysis suggests that the horseshoe crab is indeed a crab, as was originally thought. DNA analysis suggests that the oviraptor and cassowary bird share a common ancestor.

Accepted Answer

DNA analysis suggests that what was considered one species of African elephant is in fact two species.

Question 3

Which term describes the variety of internal and external forms in living organisms. Ecosystem Diversity Structural Diversity Genetic Diversity Species Diversity Biological Diversity

Accepted Answer

Structural Diversity

Question 4

Which type of fungi traps live prey? Saprobial Fungi Parasitic Fungi Predatory Fungi Mutualistic Fungi Fungi Imperfecti

Accepted Answer

Predatory Fungi

Question 5

You are given an organism and you are told it has cell walls with peptidoglycan. Which type of organism do you conclude it is? Virus Prokaryote Eukaryote Prokaryote or Eukaryote Virus of a Prokaryote

Accepted Answer

Prokaryote

Question 6

Which statement about evidence for the endosymbiotic theory of eukaryotic evolution is false ? The two organelles that present the strongest evidence are the nucleus and the cell membrane. The mitochondria and chloroplasts reproduce by binary fission. The gene sequences in mitochondria and chloroplasts closely match those of living prokaryotes. Ribosomes of mitochondria and chloroplasts are structurally similar to those of prokaryotes. The membranes of chloroplasts and mitochondria are similar to those of living prokaryotes.

Accepted Answer

The two organelles that present the strongest evidence are the nucleus and the cell membrane.
