Suppose we want to discover whether or not the consumption of alcohol causes people to be less picky in choosing a short-term sex partner. In order to test the hypothesis, an experiment is designed in which intoxicated and non-intoxicated individuals are asked to rate the attractiveness of an image of another person on a scale of 1-5. For this experiment, an appropriate hypothesis could be ________, and an appropriate prediction could be ________.
Select one:
a. We think alcohol makes people have sex. People who are intoxicated perceive potential mates as more attractive than they would sober.
b. People who are intoxicated perceive potential mates as more attractive than they would sober. Intoxicated individuals will rate images of individuals as more attractive than will their non-intoxicated counterparts
c. Intoxicated individuals will rate images of individuals as more attractive than will their non-intoxicated counterparts. People who are intoxicated perceive potential mates as more attractive than they would sober.
d. Enzymes in the liver metabolize alcohol at a rate of 1 oz per hour. People who are intoxicated perceive potential mates as more attractive than they would sober.

b. People who are intoxicated perceive potential mates as more attractive than they would sober. Intoxicated individuals will rate images of individuals as more attractive than will their non-intoxicated counterparts

Collagen is the most abundant protein found in mammmals, and it makes up the structure of connective tissue. In humans, the protein is composed of 1678 amino acids. The first 30 nucleotides of its mRNA sequence are shown below. Using this sequence and the chart on page 25 of the lab manual, determine the first 10 amino acids of collagen:
