Why is it necessary to heat a loop to redness when flamed? Why is it necessary to cool a loop after it has been flamed BEFORE placing it into a bacterial culture? What are three qualities of an effective and useful bacterial smear? What would happen to a smear if you failed to heat fix the slide before staining? Differentiate between a differential stain and a special stain (how are they different‚ don’t simply identify the types of differential stains and special stains). What

cells do not‚ white blood cells protect while red blood cells transport‚ and red blood cells have a longer life span than white blood cells. 3. Which type of white blood cell would you expect to be most common in a normal blood smear? (2 Marks) In a normal blood smear‚ one would expect to find more neutrophil cells. 4. A differential count of white blood cells from a patient gave the absolute number of lymphocytes as 8000 per mm3 and the total number of white blood cells as 12‚000 per mm3. Calculate

Cell Biology 1 – Prokaryotes & Viruses * Eukaryotes have a membrane whereas a prokaryote has no nuclear membranes. Both have a double stranded DNA. * The two main types of prokaryotes are bacteria and Archaea and eukarya are types of eukaryotes. * Archaea are more closely related to eukaryotes. * Prokaryotes have a membrane and nucleoid and most have a cell wall. * There are 3 main types of shapes of prokaryotes: * Bacillus – rod shapes * Spirilum – spiral shaped
