1. Living organisms play an important role in the recycling of many elements within an ecosystem. One such way this idea can be proven is through the study of carbon in an ecosystem. Plants‚ for starters‚ are a major part of this carbon cycle. During photosynthesis‚ plants remove carbon dioxide from the atmosphere and release oxygen as a waste product. Another major contributor to this vital cycle is the human being. The average human being goes through respiration each day to help maintain

Let every eye negotiate for itself‚ and trust no agent. William Shakespeare I. Teacher to Teacher Dialogue Agency law is very important in a basic undergraduate law course in that it represents a synergy of two otherwise distinctive bodies of law: contracts and torts. Because these topics are a precondition to a good foundation to agency‚ I never teach agency before having taught both contracts and torts. In addition‚ I have found it useful to remind students of the constant

CHAPTER I INTRODUCTION A lot of people have been getting into the weight-loss bandwagon. Nowadays there are numerous supplements and drinks that promise significant weight loss after a certain amount of time following regular consumption. One famous chemical currently advertised is L-carnitine. The substance is water soluble which oxidizes and transports long chain fatty acids into the mitochondrion (Dokmeci et al.‚ 2005; Gulcin‚ 2006)‚ transeterifies and acetyl-CoA‚ oxidizes branched chain

AP Biology notes: Chapter 2- The Chemical Context of Life 1. Overview * The bombardier beetle fights the ants that plague it by using chemistry. * The natural systems and environment that organisms live in involves chemistry and physics. * Biology is not the only category of science. There is also chemistry‚ physics‚ and engineering. * Organization of life is separated into a hierarchy of structural levels. 2. Elements and Compounds * Matter- anything that takes up

Dialysis tubing We did this experiment to test the diffusion of different substances through dialysis tubing. We used what we knew about diffusion to make predictions on what we thought the mass of the dialysis tubing to be after submerging them for 30 mins and we knew that diffuse occurs from highest concentration to lowest concentration. Since the dialysis tubings are filled with different substances than what they are being put into then they should all gain or lose mass. If the dialysis tubing

AP Bio p. 6 December 8‚ 2011 AP Biology Lab 5: Cellular Respiration Introduction/Lab Objective: In this lab we are testing how the process of cellular respiration is affected by temperature‚ and also how it is different between germinating and non-germinating peas. Cellular respiration is a catabolic process (breaks down organic material into usable cell energy) that produces ATP. The electron receivers are inorganic. Cellular respiration releases energy from organic material through chemical
