Exam 2: Biology, Genetics, and Evolution

Generation after generation,the bullfrogs in a farm pond look much alike,have the same cells,and exhibit the same behavior when breeding.This appearance of stability is linked primarily to:

Which of the following has figured most prominently in human evolutionary studies?

Modern taxonomy,or the science of classification,is based on:

The U.S.government found that Africans seeking asylum on the basis of family reunification had committed fraud in 80% of the tested cases.What is the best possible explanation for this high degree of dissonance between what the individual said and what the genetic test showed?

Why did the U.S.government begin genetic testing among Africans seeking asylum in the country in 2008?

Why does evolution matter?

How do each of the four evolutionary forces contribute to diversity of life on Earth?

Distinguish among cladogenesis,anagenesis,and punctuated equilibrium.

Clinal analysis allows anthropologists to study how populations have adapted regionally.

Sister chromatids have most directly to do with:

Explain the relationship between the origin of the discipline of biology,the theory of evolution,and the cultural changes in Europe during the early 19th century.

Why is natural selection often thought of as "survival of the fittest"?

What is DNA?

Both creation stories and the theory of evolution account for the diversity of life,yet they differ in so many other ways.Discuss the major differences between these two approaches and why you think creation stories retain so much significance today in spite of science.

The smallest working units in biological classificatory systems that are reproductively isolated populations or groups of populations capable of interbreeding to produce fertile offspring are called:

Explain the difference between analogies and homologies,and give specific examples of each.

French scientist Rosalind Franklin pioneered work in DNA sequencing in 1955.

What is the relationship between natural selection and adaptation?

Which of the following statements about protein in the body is not correct?

Describe how sickle-cell anemia is an environmental adaptation.
