The poem “ The Unknown Citizen By W H Auden is a poem that pokes fun at the life of a automaton working in a factory. Reading it in a glance‚ I find the title that catches my very first attention.

between a gram positive bacteria and gram negative bacteria is the differences in cell wall composition. Prokaryotes known as eubacteria have three basic forms: rods‚ cocci and spiral. The bacterial cell wall is the single most important contributor to cell shape. In addition to shape of cell wall‚ presence or absence of flagellum‚ and if present‚ positions of flagellum‚ the eubacteria can be classified according to Gram Stain. First and foremost‚ gram positive bacteria are by and large dark

However‚ unlike the soldier who falls in a battle of war‚ the battle this individual appears to be unwittingly a part of is a social battle

Lab: Sampling Bacteria Purpose: Refer to handout sheet. Materials: Refer to handout sheet. Procedure: Refer to handout sheet. Pre-Lab Questions: 1. Why is one dish being reserved for the class as a "control"? Having a controlled variable is important in order to be able to look at what the bacteria would look like if it hadn’t been contaminated and just left as agar. Having a sample of agar that wasnt exposed to any bacteria will provide a clear picutre of what grew on the agar
