Discuss extreme environments and types of extremophiles that livethere.

During which growth phase are bacteria experiencing conditions in which microbial waste products are building up and nutrients are running low, resulting in a death rates outpacing reproduction? O 1) death phase O 2) stationary phase O 3) lag phase O 4) log phase O 5) VNC

Q 1 a) The bacterial slime layer is generally made of polysaccharides (called glycocalyx) and might be irregular over the surface of cells. Whereas capsules have a unique proteinaceous structure and are uniform over the cell.  True  False b) Which of the following describe the reason we use differential media  Allows certain microbes to grow Brings out visible differences among microorganisms based on their specific functions We use this media when we don't want some bacteria to grow in our plates None of the above is correct c) Only a minority of all microorganisms are pathogenic or cause food spoilage True False d) In an agar plate, each -----------   represents a --------------- bin the original sample. Cell, Colony Colony, Cell Cell, Generation Hour, Generation time

Why do variation in generation time exist within a single microbial species?
