1 Listeria monocytogenes is the causative of listeriosis which can adversely affect pregnan Pregnant individuals are advised to avoid consuming cold deli meat or unpasteurized dairy products to avoid potentially becoming ill The reason these foods in particular pose a threat is because Listeria can grow at 4 C in the refrigerator however it prefers higher temperatures to support optimal growth How would L monocytogenes be classified a psychrotolerant psychrotroph b psychrophile c mesophile d thermophile 2 Protein X is present in both thermophiles and mesophiles Protein X performs the same function in both thermophiles and mesophiles Generally how would you expect the protein to differ when comparing the structure of protein X between thermophiles and mesophiles a The protein in the thermophile would have more intramolecular bonds when compared to the same protein in the mesophile b The protein in the thermophile would have fewer intramolecular bonds when compared to the same protein in the mesophile c The protein in the thermophile would contain fewer hydrophobic amino acids when compared to the same protein in the mesophile d The proteins would be identical in both organisms because temperature does not affect protein structure 3 Mono Lake is located close to Yosemite National Park in California From this lake microbiologist have successfully isolated alkalophilic halophiles Which of the following is likely the best description of the water chemistry found at the lake a It has a high pH and a low salt concentration b It has a low pH and a low salt concentration c It has a high pH and a high salt concentration d It has a low pH and a high salt concentration
