Chemical Composition of Cells Testing for Proteins: The independent variable is the biuret reagent. The dependent variable is the solutions being used as follows; distilled water‚ albumin solution‚ and starch solution. If the protein is present‚ then the biuret will change to a violet color. Authors: Eliza Koundry and Jody Cote Eliza was in charge of adding equal amounts of biuret reagent to the distilled water‚ albumin solution‚ and the starch solution. Jody was

Chapter 3 Cell Structure and Function Section 3.1: Cell Theory: Cells are the smallest building unit of living organisms that can carry out all processes required for life. Almost all cells are too small to see without the aid of a Microscope. Although glass lenses used to magnify images for hundreds of years‚ they were not enough to reveal individual cells. The invention of Compound microscope was in the late 1500s by the Dutch eyeglass maker Zacharias Janssen. In 1665‚ the English scientist

Cellulitis: Cellulitis is a common skin infection caused by bacteria. Causes Staphylococcus and streptococcus bacteria are the most common causes of cellulitis. The skin normally has many types of bacteria living on it. When there is a break in the skin‚ however‚ bacteria can enter the body and cause infection and inflammation. The skin tissues in the infected area become red‚ hot‚ irritated‚ and painful. Risk factors for cellulitis include: • Cracks or peeling skin between the

Cells Now we need to discuss CELLS. You’ve probably heard of cells‚ and may even know of a few‚ such as blood cells‚ nerve cells‚ or skin cells. What are these things called cells? Cells are the smallest living things. You’ll be learning a lot about cells in this course. For now‚ however‚ I’ll introduce you to just a few basic things about them. Cells are extremely tiny organisms that carry out all of the functions of life inside a thin layer of “skin” called (unimaginatively) the CELL MEMBRANE
