Q

Three students added equal volumes of pond water to each of four beakers (I–IV) and placed each in a different constant temperature bath, maintained at 5°C, 15°C, 25°C, and 35°C, respectively. The students then added 6 water fleas, Daphnia pulex, to each of the four beakers and recorded the time in each case. After 1 hour, the students removed 3 Daphnia pulex from each beaker and each student immediately observed one Daphnia pulex under low- power magnification of a light microscope. (The transparent body of the Daphnia pulex can be seen easily under a light microscope.) Heart rates were recorded as beats per minute. The results of the experiment are summarized in the chart below.

10.	The independent variable in this experiment is the
(A)	amount of light
(B)	number of water fleas
(C)	pH of the water
(D)	temperature of the water
(E)	average heart rate

Q

Thymine is used by animal cells primarily for the synthesis of DNA. A group of sea urchin eggs was fertilized in sea water containing radioactive thymine. Following fertilization, samples of embryos were removed at regular intervals and the radioactivity in the nucleic acid was measured in counts per minute. The results obtained are shown in the figure below.16. The increase in radioactivity of the embryos with time probably results from
(A) synthesis of new proteins by the developing embryos
(B) synthesis of radioactive thymine by the developing embryos
(C) oxidation of radioactive thymine
(D) incorporation of radioactive thymine in new cell membranes
(E) incorporation of radioactive thymine in new DNA during replication

Q
  1. An appropriate control to show that this experiment measures DNA synthesis and not RNA synthesis would be to perform the same procedures but
    (A) not fertilize the eggs
    (B) sample the embryos at longer time intervals
    (C) ) add radioactive uracil instead of radioactive thymine
    (D) fertilize the eggs in sea water that does not contain radioactive thymine
    (E) count the number of cells in the embryos at the beginning and at the end of the experiment
