Bromothymol blue (BTB) is a pH indicator that is used to detect carbon dioxide (CO2). It starts as a green color when the pH is neutral but turns blue when the pH is basic and the CO2 is low, and turns yellow when the pH is acidic and the CO2 is high. A group of students conducted an experiment using two test tubes that were set up according to the table below. They placed both test tubes under an ultraviolet lamp and monitored the color change over a 24-hour period. What is the most logical observation that will be seen at the end of the 24 hours, and why?

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?
