Since there is no single approach to make ethical decisions, a person may look to cultural values, moral upbringing, present circumstances, society’s expectations, and a multitude of other variables.

When there is an ethical dilemma, what is a source that health care professionals usually turn to in order to solve the question?

Where is the bacterial chromosome located within the cell?

How do the functions of the rough endoplasmic reticulum and smooth endoplasmic reticulum differ?

Which scientist is best known for experiments that supported the theory of biogenesis, demonstrating that living organisms arise from other living organisms rather than from non-living matter?  

In binomial nomenclature, which two taxonomic categories are used to name an organism?

A microbiology student is examining a sample suspected of containing Mycobacterium tuberculosis. They note that the bacteria do not readily take up Gram stain dyes and appear acid-fast when stained using the Ziehl-Neelsen method. Question:Which structural feature of M. tuberculosis explains why it is acid-fast and resistant to conventional Gram staining?

Amoebae and certain human immune cells move using what structure or mechanism?

BONUS QUESTION. Researchers have recently discovered unusual circular RNAs in the human gut microbiota, termed Obelisks. These RNAs are small (~300 nucleotides), circular, single-stranded, and non-coding. They show ribozyme activity and are only detected in gut bacteria that are co-infected with specific bacteriophages. Interestingly, Obelisks are sometimes found inside viral particles but can also exist freely in the cytoplasm. Based on the characteristics described, which acellular pathogen type do Obelisks most closely resemble? [color1] Which of the following would be the most appropriate experimental strategy to detect and study Obelisks in the human gut? [color2] How might Obelisks influence the human gut microbiota if they replicate within bacteria co-infected by bacteriophages? [color3]
