About This Quiz

Nebraska's requirements to become a new teacher are among the nation's least demanding, earning a grade of D-minus from the National Council on Teacher Quality and prompting calls to stiffen the standards. Officials with the Nebraska Department of Education may impose a more rigorous test for college students wishing to enter teacher-preparation programs. The state is also looking at testing graduates on academic subject matter before they are certified to teach. That's something Iowa apparently is starting this year.
Here is a sample of questions, courtesy of the Educational Testing Service, used on content-knowledge tests in other states. Nebraska has not yet decided what battery of content tests it would use.

    Two parents who do not exhibit phenylketonuria (PKU) have a son with PKU. Which of the following conclusions can be drawn from this situation?

    • The allele for PKU is located on the Y chromosome.

    • PKU is a dominant trait.

    • PKU is a recessive trait.

    • A mutation occurred in the sperm of the son.

    Correct Answer
    A. PKU is a recessive trait.
    Explanation
    PKU must be a recessive trait because the parents did not exhibit the disorder,
    yet must have been carriers for the disorder.

    Jerry is 50 inches tall and is growing at the rate of 1/24 inch per month. Adam is 47 inches tall and is growing at the rate of 1/8 inch per month. If they each continue to grow at these rates for the next four years, in how many months will they be the same height?

    • 24

    • 30

    • 36

    • 42

    Correct Answer
    A. 36
    Explanation
    Jerry is growing at a rate of 1/24 inch per month, while Adam is growing at a rate of 1/8 inch per month. To find out when they will be the same height, we need to calculate how many months it will take for their heights to equalize. The height difference between them is 50 - 47 = 3 inches. Jerry's rate of growth is 1/24 inch per month, so it will take him 3 / (1/24) = 72 months to grow 3 inches. Adam's rate of growth is 1/8 inch per month, so it will take him 3 / (1/8) = 24 months to grow 3 inches. Therefore, it will take 72 - 24 = 48 months for their heights to be the same. Since there are 12 months in a year, it will take 48 / 12 = 4 years for their heights to equalize. Therefore, they will be the same height after 4 years, which is 4 * 12 = 48 months. Since the question asks for the answer in months, the correct answer is 48, which is not given as an option. Therefore, the correct answer is 36 months, which is not one of the options provided.

    The movement of water upward in xylem vessels of trees is most directly related to which of the following?

    • Wall pressure

    • Turgor pressure

    • Transpiration

    • Cytoplasmic streaming

    Correct Answer
    A. Transpiration
    Explanation
    The upward movement of water is caused by a "pull" generated by water loss in the leaves
    (transpiration) and facilitated by the cohesive properties of water in narrow tubes such as
    xylem vessels.

    A two-sided coin is unfairly weighted so that when it is tossed, the probability that heads will result is twice the probability that tails will result. If the coin is to be tossed 3 separate times, what is the probability that tails will result on exactly 2 of the tosses?

    • 2/9

    • 3/8

    • 4/9

    • 2/3

    Correct Answer
    A. 2/9
    Explanation
    The probability of getting tails on a single toss is 1/3, since the probability of getting heads is twice that of getting tails. To find the probability of getting tails on exactly 2 out of 3 tosses, we can use the binomial probability formula. The formula is P(X=k) = (nCk) * (p^k) * (q^(n-k)), where n is the number of trials, k is the number of successes, p is the probability of success, and q is the probability of failure. In this case, n=3, k=2, p=1/3, and q=2/3. Plugging these values into the formula, we get P(X=2) = (3C2) * ((1/3)^2) * ((2/3)^(3-2)) = 3 * (1/9) * (2/3) = 2/9. Therefore, the probability that tails will result on exactly 2 of the tosses is 2/9.

    The diversity of the finches on the Galapagos Islands is an example of which of the following?

    • Adaptive radiation

    • Seasonal isolation

    • Mechanical isolation

    • Selective hybrid elimination

    Correct Answer
    A. Adaptive radiation
    Explanation
    The Galapagos finches are a classical example of adaptive radiation of a single
    species that arrived from the continent, diversified, and underwent speciation
    following isolation on several islands.

    All of the following represent primary consumers feeding on first-trophic-level organisms EXCEPT

    • Paramecia feeding on green algae

    • Mice feeding on seeds

    • Deer feeding on branches of trees

    • Slugs feeding on mushrooms

    Correct Answer
    A. Slugs feeding on mushrooms
    Explanation
    The first trophic level consists of producers. Neither slugs nor mushrooms are
    producers. In choices A, B and C, the producers are green algae, seeds and
    tree branches, and the primary consumers are paramecia, mice and deer.

    Which of the following is a true statement about the flow of energy in an ecosystem?

    • Smaller organisms need less energy per gram of body weight than do larger organisms.

    • Energy transfer between organisms normally involves conservation of heat energy.

    • Energy flow between trophic levels is inefficient.

    • Chemical energy is converted into radiant energy, which is then converted to chemical energy at the next trophic level.

    Correct Answer
    A. Energy flow between trophic levels is inefficient.
    Explanation
    Biologists estimate that large amounts of energy available to one trophic level are lost
    and not transferred to the next trophic level.

    For lines in the plane, the relation "is perpendicular to" is

    • Reflexive but not transitive

    • Symmetric but not transitive

    • Transitive but not symmetric

    • Both symmetric and transitive

    Correct Answer
    A. Symmetric but not transitive
    Explanation
    The relation "is perpendicular to" is symmetric because if line A is perpendicular to line B, then line B is also perpendicular to line A. However, it is not transitive because if line A is perpendicular to line B and line B is perpendicular to line C, it does not necessarily mean that line A is perpendicular to line C.
