University of Maryland, University College BIOL 103 OLI Quiz 47 Macroevolution Quiz Attempt 1 of 2 Score:100% Points:100 out of 100 Question 1 Points: 10 out of 10 According to the phylogene... tic tree diagram above, Old world monkeys are most closely related to: · Apes (including humans) · New world monkeys · Lemurs and Lorises · Tarsiers Question 2 Points: 10 out of 10 A rare (fictitious) plant species, the Frilly Philodendron, contains a chemical that is helpful in controlling cancer. Biologists would like to find similar chemical compounds and test them for potential medical use. Which would be the most efficient strategy for finding these chemicals? · Base your search on ecology. Look in other plants that live in the same specific habitat with the Frilly Philodendron. In particular, examine all the plants that grow in the same soil type, because they will probably have similar chemistry. · Base your search on geography. Look in other plants that live in the same region as the Frilly Philodendron. They should have similar chemistry because they are exposed to similar climate. · Do a phylogenetic analysis and then look in plants that are closely related to the Frilly Philodendron. They will probably produce similar chemical compounds. Question 3 Points: 10 out of 10 How might phylogenetics help scientists fight a new flu outbreak? · All of these · Scientists could compare the genetics of the viruses and trace the source of the outbreak. · Scientists could compare the genetics of the virus to determine useful antivirals. · Scientists could compare the symptoms of the new virus with genetically related viruses.. Question 4 Points: 10 out of 10 Which of the following terms would contain all of the other terms within it i.e. which is the most inclusive. · Species · Population · Individual · Clade Question 5 Points: 10 out of 10 The formation of new biological lineages is called _____________. · sexual selection · genetic drift · mutation · speciation · natural selection Question 6 Points: 10 out of 10 We can see evidence for the relatedness of humans, wheat plants, and bacteria if we compare their… · embryonic development patterns · ribosomes · muscle cells · body structures Question 7 Points: 10 out of 10 A swarm of insects blows out to sea in a storm. They arrive at a tiny island and form a new population. After many generations, they have diverged from the source population on the mainland. The result is an island-specific (endemic) species with a close relative on the mainland. This is an example of ____________. · mutation · sympatric speciation · allopatric speciation Question 8 Points: 10 out of 10 Which form of speciation occurs while the organisms are living in the same geographic area? · Allopatric speciation · Peripatric speciation · Parapatric speciation · Sympatric speciation Question 9 Points: 10 out of 10 Speciation is the formation of a new · biological lineage. · organism. · clade. · population. Question 10 Points: 10 out of 10 Which of the following is true? · Microevolution and macroevolution are the same thing. · Macroevolution can lead to microevolution. · Microevolution can lead to macroevolution. · Microevolution and macroevolution are not related.
