Which of the following represents correctly paired DNA nucleotides? A) Adenine with Thymine B) Adenine with Guanine C) Cytosine with Thymine D) Cytosine with Adenine

Which of the following is not one of the observations made by Charles Darwin as he developed his theory of natural selection and the evolution of organisms?  

Humans produce sweat as a cooling mechanism to maintain a stable internal temperature. Which of the following best explains how the properties of water contribute to this physiological process? A) The high specific heat capacity of water allows the body to absorb a large amount of excess heat energy. B) The high heat of vaporization of water allows the body to remove excess heat through a phase change of water from liquid to gas. C) The high surface tension of water contributes to the physical process by which water leaves the body. D) The high melting temperature of water allows the body to remove excess heat through a phase change of water from solid to liquid.

The molecular structures of linoleic acid and  palmitic acid, two naturally occurring  substances, are shown in the figure. Based on the molecular structures shown in  the figure, which molecule is likely to be solid at room temperature? A) Linoleic acid, because the absence of carbon-carbon double bonds allows the molecules to pack closely together. B) Linoleic acid, because the presence of carbon-carbon double bonds prevents the molecules from packing closely together. C) Palmitic acid, because the absence of carbon-carbon double bonds allows the molecules to pack closely together. D) Palmitic acid, because the presence of carbon-carbon double bonds prevents the molecules from packing closely together.

You are conducting an experiment to determine the effect of music on the anxiety level of mice.  You have 4 enclosures which contain speakers to deliver 3 different types of music to the mice. The    4th enclosure contains no speakers. After 2 hours in their chamber, a simple blood test is performed  to determine the level of cortisol in the blood of each mouse (a measure of stress hormone). What is  the independent variable in this experiment? A) Cortisol level B) Time kept in the enclosures C) Type of music D) Number of mice in each trial
