    Which statement best describes the relationship between cells, DNA, and proteins?
    • A. 

      DNA is composed of proteins that carry coded information for how cells function.

    • B. 

      Cells contain DNA that controls the production of proteins.

    • C. 

      Proteins are used to produce cells that link amino acids together into DNA.

    • D. 

      Cells are linked together by proteins to make different kinds of DNA molecules.

  • 3. 
    Research has shown that certain body cells, known as stem cells, can develop into a variety of specialized cells. Various factors can cause stem cells to develop into different types of mature cells. These different types of mature cells result from
    • A. 

      Different antibodies and mitotic cell division

    • B. 

      Identical genetic codes and meiotic cell division

    • C. 

      Different environments of the cells and the functioning of different parts of the genetic code

    • D. 

      Similar steps in the development of the cells and a reduction in the number of chromosomes in each cell

  • 4. 
    Which statement is true of both mitosis and meiosis?
    • A. 

      Both are involved in asexual reproduction.

    • B. 

      Both occur only in reproductive cells.

    • C. 

      The number of chromosomes is reduced by half.

    • D. 

      DNA replication occurs before the division of the nucleus.

  • 5. 
    A cell resulting from the fertilization of an egg begins to divide. Two cells are formed that normally remain attached and could develop into a new individual. If the two cells become separated, which statement describes what would most likely occur?
    • A. 

      The cells would each have all of the needed genetic information, and both could survive.

    • B. 

      The cells would each have only one-half of the needed genetic information, so both would die.

    • C. 

      One cell would have all of the needed genetic information and would survive, but the other would have none of the needed genetic information and would die.

    • D. 

      One cell would have all of the needed genetic information and would survive, but the other would have none of the needed genetic information and would die.

  • 6. 
    Although all of the cells of a human develop from one fertilized egg, the human is born with many different types of cells. Which statement best explains this observation?
    • A. 

      All cells have different genetic material.

    • B. 

      Mutations occur during development as a result of environmental conditions.

    • C. 

      Developing cells may express different parts of their identical genetic instructions.

    • D. 

      Some cells develop before other cells.

  • 7. 
    Tissues develop from a zygote as a direct result of the processes of
    • A. 

      Fertilization and meiosis

    • B. 

      Fertilization and differentiation

    Which statement concerning the reproductive cells in the diagram below is correct?
    • A. 

      The cells are produced by mitosis and contain all the genetic information of the father.

    • B. 

      If one of these cells fertilizes an egg, the offspring will be identical to the father.

    • C. 

      Each of these cells contains only half the genetic information necessary for the formation of an offspring.

    • D. 

      An egg fertilized by one of these cells will develop into a female with the same characteristics as the mother.

  • 10. 
    The development of an embryo is represented in the diagram below. These changes in the form of the embryo are a direct result of
