Biology Chapter 11 Section 6: Patterns In Evolution

Which of the following pairs of animals has a symbiotic coevolutionary relationship?

The figure below is a diagram explaining which concept?

Certain bees have evolved structures that help to pollinate flowers. The flowers have evolved structures that make it easier for certain species of bees to land and collect nectar. What is this kind of evolution called?

The term that describes the process in which two or more species evolve in response to each other is convergent evolution.  

Through mutation, HIV can accumulate resistance to drugs developed for treatment. Describe the relationship between HIV and the humans who develop these drugs in terms of an evolutionary arms race.  

An example of punctuated equilibrium is the appearance of more than 4,000 mammals following the mass extinction at the end of the cretaceous period 65 million years ago.  

Convergent evolution is evolution toward similar characteristics in two or more unrelated species as they adapt to different ecological niche.

Are the shells of turtles and snails examples of convergent or divergent evolution?

Mass extinction occurs at a _________ level.

The following is an academic essay that Jae Hyun wrote on the topic of background extinction. Background extinction is one of the three major types of extinction. It has occured intermittently throughout the history of Earth. It affects at least ten different species. Some of the causes of background extinction include, but not limited to: asteroid impact, nuclear power plants, and global warming. As of now, the rate of background extinction is unbalanced by that of speciation; if this continues unabated, another mass extinction may occur on our planet. His biology instructor gave a D on his paper. The instructor said: "You fool, you deserve a F, but the reason that I gave you a D is because at least you managed to include one accurate detail." What is that one accurate detail about?
