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

LAB 05B Momentous Design Proposal name :sonia malini Date of investigation: 8 September‚ 15 September 2009 Date of submission: 29 September 2009 Purpose The main purpose of the experiment is to investigate validity of the conservation of linear momentum from three main different types of momentum‚ namely: head on collision of equal masses‚ head on collision on unequal masses and exploding carts. Theory In the 17th century‚ Isaac Newton was the one who realized that the momentum is conserved

IB HL BIOLOGY Dialysis Lab: Exploring Osmosis and Diffusion Through A Membrane Introduction: Dialysis is the flow of certain solutes through a semi permeable membrane. Dialysis is usually used on patients with failing kidneys to clinically purify blood in their kidneys‚ or other regions of their bodies. The dialysate contains waste matter that flows from the blood our of the dialysis tubing. Question/aim of lab: To test the solutions inside and outside the dialysis tubing with Benedict’s

6.1.1 Explain why digestion of large food molecules is essential. There are two reasons why the digestion of large food molecules is vital. Firstly‚ the food we eat is made up of many compounds made by other organisms which are not all suitable for human tissues and therefore these have to be broken down and reassembled so that our bodies can use them. Secondly‚ the food molecules have to be small enough to be absorbed by the villi in the intestine through diffusion‚ facilitated diffusion or active

Viscosity Question How does changing the temperature (°C) of glycerin affect the viscosity s -1 of glycerin (l)‚ when tested by dropping a marble from a constant height into the glycerin (l) and timed with a stopwatch until the marble hits the bottom? Design Independent Variable: The independent variable of this experiment is the temperature (°C) of the glycerin (l). Dependent Variable: The dependent variable of this experiment is the viscosity s -1 of the glycerin (l). Controlled Variable(s): The controlled
