Q1 >>> Which of the following statements, A to D, about differential staining is not true? A - Differential staining can distinguish between different organelles. B - Differential staining can distinguish between types of cell. C - Differential staining can distinguish between types of organism. D - Differential staining is a common feature of electron microscopy : *D* Electron microscopes produce black and white images, so stains will not show up A is true - e.g. methylene ...

are antibiotics effective against viral infections? - NO briefly describe eukaryotic cells - -contain nucleus (prokaryotes do not) -contain organelles -selectively permeable cell membrane briefly describe molds - -produce cytoplasmic filaments called hyphae/mycelia -reproduce by spore formation on aerial hyphae briefly describe T.

BIOL 1073 Microbiology for Nursing Week 1 - Course overview, policy review & introduction to Microbiology in Health & Disease. Microbiology is the study of very small living organisms. Often known as microorganisms, microbes or pathogens. Even before microscopes were invented, microorganisms still existed in this world, such as the black plague that caused 3 pandemics.

Homeostasis When organisms maintain a stable internal environment even when external conditions change Metabolism Combination of chemical reactions taking place within an organism Stimulus A signal to which an organism responds Biosphere Means "living planet" Robert Hooke Scientist who looked at cork through a microscope and gave the name to cells Light Microscope A type of microscope Can magnify 1000x Not as strong as other microscopes Uses light Scanning Electron Microscope A typ...
