This project’s purpose is to find the effects of UV light on Staphylococcus epidermidis‚ furthermore recognized as staph infection. Staph infection is an infection usually acquired on the skin that can promote fever‚ nausea‚ pain‚ boils‚ and can lead to MRSA‚ which can lead to death. Because there is no cure for staph infection‚ this experiment called for research on clinical trials. A clinical trial was established that used blue light therapy to delay and kill the growth of staph infection. Coincidentally

Problem What effect does the different concentration of hydrochloric acid have to the rate of diffusion of agar that is dissolved with sodium carbonate and phenolphthalein? Introduction Diffusion is a process where the molecules intermingle as a result of their kinetic energy of random motion and is the net movement of like molecules down their concentration gradient‚ which is the energy inherent in their constant molecular motion makes them collide and careen outward from the region of higher

loving nurturing homes‚ with people who love and cherish them. However‚ there are millions of children who grow up on the streets and in homeless shelters‚ leading a life of crime and violence; ending up in the judicial system. Although‚ when a person obtains a college degree‚ the likelihood of that person every having to live in poverty and on the streets is very slim.

The Constitution is a very significant document because it lays out the basic structure and outlines of a rather respectable and effective democratic government. Furthermore‚ having unalienable rights is necessary for any society to thrive. On top of that‚ the government must exist for the lone purpose of protecting these rights and nothing more. These constitutional principles sanction and outline two specific ideals: 1) protection of the citizen’s inalienable rights and 2) controlled governmental

Agar What is it and where is it from? Derived from the cell walls of red algae‚ agar is a gelatinous substance extracted through a process of boiling and filtration. Agar is specifically used in laboratories for diagnostics and experimental purposes. Agars main purpose is to act as a growth medium for micro-organisms such as bacteria and fungi. The micro-organisms feed off the nutrients contained in Agar and can be both cultured and observed within it by scientists and the use of a microscope. Using

Diffusion In Agar Cubes Is Bigger Better? OR Is Smaller Smarter? Adapted from Flinn Scientific Publication No. 10110 Introduction: Diffusion is one of the very important processes by which substances such as nutrients‚ water‚ oxygen‚ and cellular wasted are transported between living cells and their environment. This activity will help you explore the relationship between diffusion and cell size by experimenting with model “cells.” In this experiment‚ you will use agar cubes to which
