Course Introduction
General Biology Question
Bank
General Biology provides an introduction to the fundamental concepts of the biological sciences, covering the structure and function of cells, genetics, evolution, ecology, and the diversity of life. Students will explore the mechanisms that govern living organisms, from molecular processes within cells to the interactions of organisms within ecosystems. Through lectures, laboratory exercises, and discussions, this course emphasizes scientific reasoning, experimentation, and the application of biological concepts to real-world issues such as health, conservation, and biotechnology.

Q1) The primary treatment for giardiasis (infection with Giardia),as well as for trichomoniasis (infection with Trichomonas vaginalis)and for amoebic dysentery (infection with Entamoeba histolytica),is a drug marketed as Flagyl (generic name is metronidazole).The drug also kills anaerobic gut bacteria.Consequently,which of these are cues that Flagyl's mode of action has nothing to do with attacking or disabling the parasites' flagella,as the drug's name might imply?
1)It would also harm the flagellated lining of the human intestine.
2)Entamoeba possesses pseudopods,not flagella,yet it is killed by Flagyl.
3)Prokaryotic flagella and eukaryotic flagella are radically different from each other and unlikely to be harmed by the same chemical.
