- After some time, you found out that you did not like working in microbiology lab, so you found a job at an Environmental lab. Some park attendants said that their dogs took a dive in one of the park’s ponds and after few days they became sick. So, you went to the park and took a sample of the water to analyze it.11) To which one of the kingdoms you are expecting to find representative of that caused the dogs to become sick?12) Name the Phylum13) To which class (or group) of organisms they belong to?arrow_forwardOne approach to combat drug resistance in bacteria is to combine drugs to treat bacterial infections. For example, ampicillin, a beta-lactam antibiotic, is combined with clavulanic acid, a beta-lactamase inhibitor. Describe how these two drugs would act together to be more effective to treat a bacterial infection.arrow_forwardWhat is the purpose of each of the following ingredients when present in an homogenization buffer for isolating organelles? a.

- Many of the first prokaryotes to be cultured in a scientific lab were human or animal pathogens. Why would these species be more readily cultured than non-pathogenic prokaryotes? a. Pathogenic prokaryotes are hardier than nonpathogenic prokaryotes. b. Non-pathogenic prokaryotes require more supplements in their growth media. c. Most of the necessary culture conditions could be inferred for pathogenic prokaryotes. d. Pathogenic bacteria can grow as free bacteria, but non-pathogenic bacteria only grow as parts of large colonies.arrow_forwardWhich of the following is NOT true about bacterial endospores? A. They are produced by bacteria of the genus Bacillus and Clostridium B. They are “resting cells” for survival during adverse environmental conditions C. Resistant to desiccation (drying), heat, and chemicals D. Formed by walling off one end of the bacterial cell and surrounding it with a thick spore coat E. They represent a type of reproduction because their formation results in an increase in the number of bacterial cellsarrow_forwardA bacterium has the following characteristics: I.
