The Cycle of Violence In his autobiography‚ Fist‚ Stick‚ Knife‚ Gun‚ Geoffrey Canada exposes the reader to numerous types of violence witnessed while growing up in South Bronx‚ a subaltern community in New York. The slum is full of lower class individuals who are in a constant struggle for power‚ acceptance and safety. The book begins by discussing his childhood and how he had to learn the codes and behaviors accepted in his neighborhood and his place in the hierarchy of the street. Each block

Lab Report – Strong Example Problem/Question Does using a base coat before painting nails prevent chipping? Background Information When painting nails‚ some manicurists use a base coat before applying the polish. The purpose of a base coat is to help the polish stick to your nails more easily. Base coats also help to protect your natural nail from the staining effects of colored polishes. Ridge-filling base coats fill in the grooves and cracks in the nail to create a smoother appearance

The pGLO lab is a lab where students attempt to put the genes that make a jelly fish glow into E. Coli. After a process called transformation‚ the process in which a cell takes up and expresses a new piece of genetic information‚ the E. Coli will be able to glow and will be antibiotic resistant. The students first need to learn a couple of techniques before they are able to begin this lab. The first technique they will need is how to keep their environment sterile. They must learn to only open their
