Aim: 1) To determine the effects of different salt concentration on the percentage of weight change in potato cubes 2) To determine the isotonic solution concentration for the potato Hypothesis: 1) If the concentration of the salt solution is higher than the concentration in the potato cubes‚ the percentage of weight change in potato cubes will be higher (positive). If the concentration of the salt solution is the same as the concentration in the cell‚ there will be no net movement of water through

Biology 20 IB Design Lab Does increasing or decreasing the ph level of a 3% concentration H2O2 (l) solution affect the amount of oxygen released between 15.0ml of the solution and a 5g sample of liver? The reaction is measured by the difference in mass of a balloon that is used to capture the amount of gas released by the catalase enzyme found in liver reacting with a basified 3% H2O2 (l) and an acidified 3% H2O2 (l) . Chemical reactions occur when two or more molecules interact and the molecules

Evolution Lab “Evolution by Natural Selection” The object of this experiment is to determine how changing the size of the beak of a finch will affect the population as well as the growth rate of the finch’s beak. The reason for the experiment is to evaluate evolution and how it affects the finch’s population‚ and how natural selection is always present in life. In this experiment I will show that the finch will continue to evolve until its beak has reached the optimal size for sustaining

Practical 1: Observation of mitosis in garlic root tips Introduction The practical will involve the preparation‚ observation‚ and classification‚ of the various stages of mitosis by observing garlic root tips using a microscope. The study comes under the heading of cytogenetics which is the visual characterisation of genetic material and the study of how that material reacts during the life of the cell. Strictly speaking‚ mitosis is the division of the nucleus into two daughter nuclei that are
