Please use this information to answer the following question(s).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 your 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 three instances, the females did not mate with either type. A picture of the lizards is below:    Answer the following question.If the proportion of brightly colored male lizards increased steadily in future generations, this would ________.

All of the following molecules are organic EXCEPT:

For a given substance, the amount of light absorbed depends upon which of the following?

What would you expect to happen to the absorbance reading of a spectrophotometer if the pathlength of the cuvette increased from 1 cm to 2 cm based on Beer’s Law?

Please read the following scenario to answer the following questions.While radioactive isotopes are used in medicine to identify tumors and other diseases, they can also be used to treat diseases such as cancer. One method to treat cancerous tumors is to expose them to radiation which can kill the cancerous cells and the tumor. In 2013, the U.S. Food and Drug Administration approved a new cancer treatment based on the radioactive isotope radium-223; this isotope has a half-life of 11.4 days. The radioactive drug, known as Xofigo®, is injected into the patient’s bloodstream and travels to certain regions of the body. Because it emits high-energy radiation over short distances, it can kill cancerous cells in the sites where it localizes.After the drug was injected into a person, the following data were collected regarding the amount of radiation measured in different organs in the person’s body. Organ Measured radiation Brain 0.37 Liver 11.01 Bones 4262.60 Lungs 0.27 Urinary bladder 14.90 Using the above table, what kind of cancer do you think Xofigo® is used to treat?
