    A farmer wishes to develop a strain of high-yield corn that is also resistant to drought. He has the following individuals from the current year's crop:

    Individual A—Yield: 179 bushels/acre; drought resistance: high

    Individual B—Yield: 220 bushels/acre; drought resistance: low

    Individual C—Yield: 185 bushels/acre; drought resistance: medium

    Individual D—Yield: 140 bushels/acre; drought resistance: high

    Individual E—Yield: 200 bushels/acre; drought resistance: medium

    Which of the following crosses would produce the highest corn yield with the highest resistance to drought?

    A and E

    An adaptation is _____.

    a trait that gives an organism a reproductive advantage in the current environment

    Which one of the following researchers developed a theory of evolution that was very similar to Charles Darwin's?

    Wallace

    A group of small fish live in a lake with a uniformly light-brown sandy bottom. Most of the fish are light brown, but about 10% are mottled. This fish species is often prey for large birds that live on the shore. A construction company dumps a load of gravel in the bottom of the lake, giving it a mottled appearance. Which of these statements presents the most accurate prediction of what will happen to this fish population?

    The proportion of mottled fish will increase over time.

    Identify the four postulates of natural selection.

    1. Individuals in a population vary in the traits they possess.

    2. Some trait differences are heritable.

    3. Survival and reproductive success are variable among individuals in a population.

    4. Individuals with certain traits are more likely to survive and reproduce.

    Which of the following statements is an accurate combination of postulates 1 and 2 of natural selection?

    Heritable variation exists for traits among individuals in a population.

    Which of the following statements is an accurate combination of postulates 3 and 4 of natural selection?

    Individuals experience differential success in their ability to survive or reproduce due to differences in certain traits.

    Does the ability of a Mycobacterium tuberculosis cell to infect a new host depend on its drug-resistant phenotype?

    No, drug-susceptible cells and drug-resistant cells are equally likely to infect a new host.

    Which of the following statements describes the evolution by natural selection of Mycobacterium tuberculosis bacteria in their new environment?

    The drug-resistance trait is an adaptation to the environment in which human hosts are medicated with the antibiotic rifampin.

    In the United States today, about half of the corn crop is genetically engineered with a protein that is toxic to corn borers, an insect pest of corn. Which of the following conditions would be necessary for evolution of resistance to the toxic protein to occur in the corn borer?

    The corn borer must have or generate (by mutation) heritable variation in resistance to the toxic protein. The resistant corn borers must survive better or reproduce more than nonresistant corn borers.

    True or false? It would be difficult to assess whether the drug-susceptible or drug-resistant phenotype in a population of Mycobacterium tuberculosis was more fit in an environment without antibiotics.

    True

    Introduction To Biology

    A process in which organisms with certain inherited characteristics are more likely to survive and reproduce than are individuals with other characteristics is called

    Natural selection. Natural selection is the mechanism that explains how life evolves.

    Evidence from molecular biology supports the theory of evolution by showing that __________.

    Closely related organisms have more similar DNA and protiens

    Which of the following is the study of the geographic distribution of species on Earth?

    Biogeography

    Which one of the following statements most closely agrees with the theory of evolution by means of natural selection, as put forth by Darwin?

    Organisms better adapted to their immediate environment are most likely to survive and reproduce

    Which of the following is not a requirement for natural selection?

    variation in individuals

    Scientists have warned doctors of the danger of their increasing use of antibiotics (for instance, penicillin) for treating minor illnesses. They are concerned because _____.

    strains of microorganisms that are resistant to these drugs will increase

    A population is __________.

    a group of individuals of the same species occupying a given area

    While on the beagle Darwin was influenced by a book by Charles Lyell that suggested that earth was___and sculpted by geologic process that ___ today.

    old...continue

    Animals that possess homologous structures probably _____

    evolved from the same ancestor

    The approach to evolution that involves the study of similar structures that appear during the development of different organisms is known as the study of _____.

    comparative embryology

    scientists who study fossils

    paleontologists

    Homology is evidence of ______.

    common ancestry

    "Natural selection" and "evolution" are two terms that are sometimes confused, even by freshman biology students. What is the relation between natural selection and evolution?

    Natural selection is one of several mechanisms of evolution.

    A group of small fish live in a lake with a uniformly light-brown sandy bottom. Most of the fish are light brown, but about 10% are mottled.

Which of these statements presents the most accurate prediction of what will happen to this fish population?

    Your Answer: The proportion of mottled fish will increase over time.

    Which of the following is a requirement of natural selection?
