BLOOD 1. The important components of blood include plasma‚ erythrocytes‚ and leukocytes. Red blood cells or erythrocytes account for 45 % of the blood. Leukocytes or white blood cells‚ aid in protecting the body from disease as well as platelets. Platelets function to inhibit excessive bleeding from the body. The plasma layer is another layer that constitutes the majority of blood. 2. The Plasma is straw coloured. It has 90% water‚ 7%proteins and 3% other substances. The Plasma protects the

In December 1988 Sarah Smith was in a serious car accident. Sarah became paralyzed from the waist down. She seldom felt nerves in her legs and feet when touched or tested and she could not walk or stand. The muscles in her hands had atrophied‚ making it impossible for her to open them. Sarah’s’s health gradually got worse due to lack of exercise and movement. In essence she lived in a motorized wheel chair. After reading an article Sarah contacted the Rehabilitation Institute of Detroit‚ Michigan

Induced Pluripotent Stem Cells and Embryonic Stem Cells Induced pluripotent stem (iPS) cells made from human somatic cells are a very recent technology of our world. They were first created using mice in 2006‚ and were created from human cells in 2007 by Japanese and US scientists. For many people‚ they represent a beautiful work of science that will help to save many lives. Induced pluripotent stem cells are human skin cells that have been reprogrammed to have the stem cells ability to

Plasma membranes are selectively permeable. The purpose of this experiment is to reveal how a form of diffusion in a semipermeable membrane works by creating a real life simulation of a semipermeable plasma membrane. This is done by building an imitation of a caterpillar’s digestive tract using dialysis tubing and glassware. The first material in this experiment is a small beaker representing the head and crop of the caterpillar. This beaker is filled with both starch and the enzyme α-amylase. This
