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

African Diaspora and the World After reading the short story “Diaspora” by Joanne Hyppolite‚ I got a vivid understanding of how diaspora can have an effect on one’s identity. Over the past month we have studied many theories and concepts concerning race‚ gender‚ and politics. There are three theories that capture the essence of Joanne Hyppolite’s worldview as a Haitian growing up in America: intersectionality‚ identity‚ and diaspora. Individuals oftentimes experience the theory of Intersectionality

Unit 5 – Anatomy and Physiology for Health and Social Care Cells Introduction For this assignment I will have to talk about the organisation‚ e.g. cells‚ tissues‚ organs and systems. And the cells‚ e.g. cell membrane‚ nucleus‚ cytoplasm; organelles- mitochondria‚ smooth and rough endoplasmic reticulum‚ golgi apparatus and lysosome. Organisation; Every individual is composed of billions of microscopic units called cells. The cells carry out vast numbers of chemical reactions and processes

In each station there was a positive and a negative control. If the substance was the same as the negative control then it was negative. If the substance was the same as the positive control than the substance is positive. In the first lab we did the Paper Spot test‚ one would have had to apply the substance on a cardboard like paper. If it looked oily it was the biomolecule called lipid. The result of test one was it stayed the same‚ it did not turn oily and was clear. Next was the test

Introduction The purpose of this lab is to determine the percent mass of Cu in a penny and see if the fabricator that makes the planchets for the government is using the correct amounts of Cu in the pennies. The composition of a standard penny is 97.5% Zn and 2.5% Cu. In the lab we will be using Beer’s Law (A=elc+b where A is solution absorbance‚ e is a constant called molar absorbency‚ l is the length in cm‚ and c is the concentration). Using Beer’s Law in this lab a colorimeter is used to find the
