1 The Effect of Molecular Weight on the Rate of Diffusion of Substances1 Alexander Ken Libranza Group 1 Sec. A – 1L March 6‚ 2012 A scientific paper submitted in partial fulfillment of the requirements in General Biology I laboratory under Prof. Cheryl M. Talde‚ 2nd sem.‚ 2011-2012. 1 2 ABSTRACT The effect of molecular weight on the rate of diffusion was assessed using two tests: the glass tube test and the agar-water gel test. In the glass tube set-up‚ two cotton plugs soaked

Stress and Cellular Membranes Bio Lab SBI 4U1 Due: Sept 24th‚ 2010 For: Ms. Barton By: Ameema Saeed Introduction: (See attached lab) Purpose: (See attached lab) Hypotheses: Tap water will cause no damage to the membranes. The extreme temperatures of the water cooled to 0°C‚ and heated to 94-100°C will greatly damage the membranes. Extreme heat will be more damaging than extreme cold. The more concentrated the solvent‚ the more damage it will cause to the membranes‚ therefore the solvent

Practical 2.1- The Effect of Temperature on Membranes Objective To investigate the effect of temperature on membrane structure Introduction Beetroot Pigments Beetroots contain Betalains which are the red pigments present in the cell vacuole. Betalains are soluble in water and they contain nitrogen. Betalains extracted from beetroot is commonly used as food dye because it is not known to cause any allergic reactions.

Physical Science lab #5 Objective The goal of this experiment is to develop a theory‚ which allows us to understand the motion of a marble. Materials Wooden roller coaster‚ marble‚ ruler‚ timer‚ clamp‚ physics stand. Theory In this experiment‚ we are finding the Conservation of Energy. Energy is neither created nor destroyed. Energy is summed up into two different properties: Potential energy and Kinetic energy. The law of Energy states that: Total Energy = Potential
