d) 67.5 J

Determine the rate of oxygen consumption at each temperature for comparison. Then divide the higher rate by the lower rate to obtain the difference (ratio) between the two temperatures. Round your answer to the nearest 0.1. It can be concluded that mouse respiratory rate (increases or decreases) when temperature is lowered. In this experiment there was a fold difference in respiratory rate at the two temperatures.

You perform an experiment in which chromatin is isolated from sea urchin sperm cells and briefly digested with micrococcal nuclease. When the chromatin proteins are removed and the resulting purified DNA is analyzed by gel electrophoresis, you observe a series of DNA fragments that are multiples of 260 base pairs in length (that is, 260 bp, 520 bp, 780 bp, and so forth). a) Although these results differ somewhat from the typical results discussed in the chapter, explain why they still point to the likely existence of nucleosomes in this cell type. b) What can you conclude about the amount of DNA that is associated with each nucleosome

A cluster of cases of legionellosis have occurred in your neighborhood. People with the illness have cough, fever, shortness of breath, chest pain and sometimes diarrhea. The illness is caused by the bacterium Legionella pneumophila, a facultative intracellular parasite that survives in certain ameba. The organism has an absolute requirement for L-cysteine. Typically, the organism is grown on buffered charcoal yeast extract (BCYE) agar. In some labs, samples containing suspected L. pneumophila are cultured on traditional BCYE medium as well as BCYE medium lacking L-cysteine. How would L. pneumohila be identified in this situation

The mutations responsible for the dark fur color in the Arizona mice were absent from the three different populations of New Mexico mice. No Mc1r mutationswere associated with dark fur color in the New Mexico populations. These findings suggest that adaptive dark coloration has occurred at least twice in the rock pocket mouse and that these similar phenotypic changeshave different genetic bases. How does this study support the concept that natural selection is not random

Emilia Burton is an 18-year-old high school student who began to experience weight loss despite a ravenous appetite and resulting increased dietary intake. She has to make frequent trips to the bathroom to urinate and has difficulty concentrating on her work because of fatigue.
