Osmosis Lab Report by Evan Gerber Claire Cambron First Lab Report Wednesday 10:30am February 20‚ 2013 Theresa Gburek Abstract The major objective of the experiment was to test the effect of the concentration gradient on the diffusion rate. It was hypothesized that the greater the stronger the concentration gradient‚ the faster the rate of diffusion would be. To test this‚ dialysis tubes were submerged in different concentration fructose solutions. We weighed the tubes at specific

provides energy for one’s body. (Metabolic is elevated) 3. In a person’s body that exercises‚ the lungs are important in sending more oxygen to the person’s cells‚ because the body consumes all available resources. The person’s body takes in oxygen quicker as they exercise‚ resulting in the person breathing harder/faster to keep up with the rate consumption. 4. During exercise‚ the oxygen enters into the bloodstream leading to the lungs and the cells take in the oxygen (capillary sacs). As the blood flows

Shalacia Gilmore Fall 2012 BIO 1107 Natural Selection Lab INTRODUCTION In the 1850s‚ two scientists by the name of Charles Darwin and Alfred Russell Wallace composed the theory of evolution by natural selection. (1) Darwin characterized several claims needed for natural selection to happen‚ including heritable variation within the population‚ and the presence of more individuals than the environment can support. They also discovered that certain environments favored certain traits. These

artery carries blood from the aorta to the kidney. The nephron has a cup-shaped nephric capsule that surrounds a cluster of capillaries called the glomerulus. A good deal of fluid from the blood filters into the capsule. Large proteins and whole blood cells are left behind due to the fact that their too big to pass through the filters along with the plasma or blood fluid. There are four main parts of the nephron tubule: the proximal convoluted tubule‚ the U-shaped loop of Henle‚ the distal convoluted
