Staphylococcus aureus is a type of bacterium that can cause infections in humans. These bacteria can exist for long periods of time in air, dust, water, and food, as well as on environmental surfaces. Rhinovirus is a type of virus that can cause the common cold in humans. Rhinovirus cannot survive outside of a human host for more than a few hours.
Which of the following best describes a major difference between bacteria and viruses?
A. Viruses can cause infections in the human body, whereas there are no types of bacteria that can cause infections.
B. Bacteria cannot survive without a living host, whereas viruses can often live and grow outside of the human body.
C. Bacteria can cause infections in the human body, whereas there are no types of viruses that can cause infections.
D. Viruses cannot survive without a living host, whereas bacteria can often live and grow outside of the human body.

The collared lizard is a species found in the desert southwest. male collared lizards show considerable color variation, ranging from brightly colored to a very dull pattern. your goal is to determine the function, if any, of male color patterns in collared lizards, using the scientific method. your tentative explanation is that male color plays a role in attracting females for mating purposes. you predict that females will preferentially choose brightly colored males over dull-colored ones. to test this prediction, you observed the interactions of female collared lizards with their male counterparts. you selected males that were the same age and size, and that differed only in their coloration pattern. you placed equal numbers of the two types of male lizards, bright and dull, in aquariums, along with one female lizard per aquarium. out of 350 aquariums observed, the female chose to mate with the brightly colored male 277 times, and the dull-colored male 70 times. in 3 instances, the females did not mate with either type. create a bar graph of your data, plotting the type of male (dull or brightly colored) on the x-axis. on the y-axis, plot the frequency with which each type of male was chosen by females. using this graph, answer the following question(s). is it reasonable to conclude (i.e., is it supported by the data) that female collared lizards prefer more brightly colored male lizards over dull-colored males?
