What is microbiology? correct answers the study of microbes, examines how they interact with humans&food as well as how they can be used by humans basis for molecular biology and biotechnology Microbes vs Microorganisms correct answers Microorganisms are archaea, eukaryotes, and bacteria. Microbes include microorganisms as well as viruses Classifying microbes correct answers was a challenge historically because of the difficulties in observing distinguishing characteristics of different...

Not very many proteins in the eukaryotic cytoplasmic membrane. Where did they go? correct answers They are still in the membrane and they are still busy, but most of the proteins went to the mitochondrial membrane in eukaryotes. Cellulose and Chitin correct answers Use specific b-1,4-glycosidic bonds between sugars provides strength and rigidity. In algae Fungi - Cell Wall correct answers You have a NAG in chitin for cell walls in fungi. The cell wall is all NAGs Cytoskeleton Function c...

What is microbiology? correct answers The study of microbes examines how microbes interact with humans, with food, and how they can be used by humans Microbes correct answers Everything small that we might study as microbiologists. Viruses, archea, eukaryotes, and bacteria Microorganism correct answers Excluding viruses, inert particles don't adhere to the strict definition of life so they are not included under the topic of microorganisms Prokaryotic correct answers Before the nucle...

BIOL 2401 EXAM 4 Questions With Complete Solutions

Effect of osmotic pressure on cells correct answers The changes in diffusion gradient of water -Higher osmotic pressure, more stress on cell Cells are 80-90% H2O Cell walls resist hypotonic solutions, but few organisms can resist hypertonic solutions Isotonic Solution: No net movement of water particles. Cell membrane is attached to cell wall. Hypertonic Solution: Water particles move out of the cell. Cell membrane shrinks and detaches from cell wall (plasmolysis) Hypotonic ...
