Take This Biology Trivia! Ultimate Quiz

What do you know about biology? Biology is the natural science that examines life and living organisms, including their physical structure, chemical processes, molecular interactions, physiological mechanism, evolution, and development. Even though this is a very involved form of science, certain unifying concepts merge into a single coherent field. How much do you know about biology? Take the quiz and see.


Questions and Answers
  • 1. 
    Darwin's theory of natural selection requires all of the following EXCEPT:
    • A. 

      Individuals within a species vary

    • B. 

      Survival and reproduction of individuals are non-random

    • C. 

      Some of the variation between individuals is heritable

    • D. 

      Natural selection leads species to generate new beneficial mutations to meet local conditions

    • E. 

      More offspring are produced than can survive

  • 2. 
    According to the theory of natural selection, what factor below contributed to the current variations in beak sizes of finch species on the Galapagos islands?
    • A. 

      Seeds are a limited resource

    • B. 

      Finches dispersed to islands where their beak sizes closely matched available seed sizes

    • C. 

      Non-heritable variation between individual was important for natural selection to work

    • D. 

      Different finch populations needed to change in order to survive, so beneficial new traits arose

    • E. 

      Genetic drift allowed beneficial traits to spread throughout the population

  • 3. 
    Which of these lists contains the four postulates of natural selection?
    • A. 

      Uniform population, heritable traits, selection, differential survival or reproduction

    • B. 

      Variation in population, environmental variation, selection, differential survival or reproduction

    • C. 

      Variation in population, heritable variation, selection, unlimited survival and reproduction

    • D. 

      Variation in population, heritable variation, selection, differential survival or reproduction

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

      Individuals experience no success in their ability to survive or reproduce.

    • B. 

      Individuals experience differential success in their ability to survive or reproduce.

    • C. 

      Individuals experience uniform success in their ability to survive or reproduce.

    • D. 

      Individuals experience unlimited success in their ability to survive or reproduce.

  • 5. 
    Which of the following statements describes the evolution by natural selection of Mycobacterium tuberculosis bacteria in their new environment?
    • A. 

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

    • B. 

      The drug-susceptibility trait is an adaptation to the environment of antibacterial soaps.

    • C. 

      The drug-resistance trait is an adaptation to the environment in which human hosts travel worldwide and are exposed to new strains of bacteria.

    • D. 

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

  • 6. 
    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?
    • A. 

      The corn borer must lack variation in resistance to the toxic protein.

    • B. 

      The corn borers must experience no success in their ability to survive or reproduce.

    • C. 

      The corn borers must experience unlimited success in their ability to survive or reproduce.

    • D. 

      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.
