  • Q #1: In order to determine the effects of energy drinks on women's running speed, researchers gave 300 women an energy drink and then recorded the time it took each of them to run 2 miles. After collecting the results, researchers concluded that energy drinks increase the speed of running in Which of the following further tests would best help to support this conclusion?

    A. Repeat the same experiment, using 300 men

    B. Repeat the experiment giving half of the women water and the other half the energy drink

    C. Repeat the experiment giving the women two different energy drinks

    D. Repeat the experiment, having half of the women run 2 miles and the other half run 5 miles

    Answer Explanation

    Conducting the experiment with half the women taking water and the other half taking an energy drink creates a study and experimental group, which can allow for comparison and conclusion. The researchers can compare the effects of the energy drink directly with a baseline, and this helps to establish a cause-and-effect relationship and provides stronger evidence to support their conclusion.

  • Q #2: Which of the following pathways best represents the expected flow of blood from the human heart to an organ?

    A. Blood pumped from the heart first enters arterioles that then merge to form arteries that deliver blood to the organ

    B. Blood pumped from the heart first enters arteries that then narrow to form arterioles that deliver blood to capillaries of the organ

    C. Blood pumped from the heart first enters versus that then narrow to form venules that deliver blood to arteries to the organ

    D. Blood pumped from the heart first enters arteries that then narrow to form arterioles that deliver blood to capillaries

    Answer Explanation

    From the heart, blood flows through major arteries, which then branch to give rise to arterioles, which then divide into capillaries that deliver blood to the target organ.

  • Q #3: A strand of DNA bases reads 5' AGCTAGCGT 3, what would the sequence of bases on the contemporary strand read?

    A. 3' STOGUTCGCU

    B. 5' AGCTAGCGT S

    C. 3' SUCGAUCICA

    D. 3' TCGATCGCA 5'

    Answer Explanation

    The complementary strand of DNA is formed by pairing complementary bases. In DNA, adenine (A) pairs with thymine (T), and guanine (G) pairs with cytosine (C). Additionally, RNA uses uracil (U) instead of thymine.

    Given the sequence 5' AGCTAGCGT 3', the complementary strand would read:

    3' TCGATCGCA 5'
