BIOLOGY Biology is the study of life -- life in all of its grandeur. From the very small algae to the very large elephant‚ life has a certain wonder about it. With that in mind‚ how do we know if something is living? Is a virus alive or dead? What are the characteristics of life? These are all very important questions with equally important answers. Characteristics of Life Living tings include both the visible worlds of animals and plants as well as the invisible world of bacteria and viruses.On

Lab: Inhibiting the Action of Catechol Oxidase By: Kimberly G. Introduction: In this lab‚ Mr. Greene ’s sixth period AP Biology class split into groups "to investigate inhibition of enzyme activity by specific chemicals called inhibitors" (1). Group three pondered this lab ’s inhibitor‚ phenylthiourea (PTU). Is it a competitive inhibitor? That is an inhibitor that literally "competes" with the substrate by mimicking it‚ and thus "wins" the position at the active site of the enzyme. The blocked

This case study describes what happens when a health district merges four laboratories into one unit due to external driving forces for change‚ primarily the government funding cuts. Although the intention was to develop one centralized‚ efficient‚ and high volume centre‚ the inattention to the ‘people issues’ and the cultural differences of the work units results in chaos. The recently hired laboratory manager‚ Claude‚ has implemented several stopgap measures intended to address the work load issues

Debbie Cao IB Chemistry 12 Pressure/Volume of Air Full Lab Write Up Introduction: According to Boyle’s Law‚ the volume of any given amount of gas held at a constant temperature varies inversely with the applied pressure. In other words‚ when the pressure increases the volume decreases. When pressure decreases‚ volume increases. This can be derived from the following equation: P1 V1=P2 V2 The common use of this equation is to predict how a change in pressure or volume will alter the
