This experiment was designed to study the effect of exercise on skin temperature and heart rate. Studying the effect of exercise on skin temperature and heart rate yields understanding of how homeostasis is achieved in humans. This knowledge creates opportunity to discover more effective ways to return the human body to optimal functioning‚ rather than a reliance on natural processes. This experiment measured the change in skin temperature and heart rate of a chosen subject for four two-minute intervals

Daphnia play an important role in the freshwater food chains and serve as food for other freshwater organisms such as fish. They are also commonly used to test for chemical toxicity in water. Since Daphnia have transparent body‚ it is easier to observe their heart rates‚ and other visceral organ systems. Its small heart rate is easily visible when viewed under a microscope. A change in its heart rate plays a crucial role in

Practical Assessment 2 – The effect of substrate concentration on the rate of enzyme activity of Catalase Aim To investigate the effect of substrate concentration (manipulated by increasing concentration of hydrogen peroxide) on the rate of enzyme activity of catalase‚ produced by liver cells‚ on the decomposition of hydrogen peroxide. Introduction Enzymes are biological catalysts that increase the rates of reactions. In an enzyme-catalyzed reaction‚ the substrate binds to the active site

Cellular metabolism encompasses the many processes that work together to keep the cells in dynamic equilibrium. Cellular metabolism is responsible for providing energy to the cell and is an essential element of life. There are several complex‚ involved processes involved in cellular metabolism including glycolysis‚ Krebs’s cycle‚ and electron transport. Metabolism itself can be broken down into two different categories: catabolic and anabolic. Catabolic metabolism involves the breakdown of large

Measuring the Effect of Light Intensity on Photosynthesis Introduction Photosynthesis captures energy from sunlight. Plants‚ algae‚ and some bacteria use the energy captured during photosynthesis for their metabolic reactions. During photosynthesis in plants‚ chlorophyll and enzymes in leaves convert certain wavelengths of light into chemical energy. A simple equation can be used to represent photosynthesis. Enzymes and Chlorophyll light energy CO2 H2O carbohydrate O2 In this investigation

This House would ban animal testing In this debate testing should be defined as all testing including‚ medical research‚ cosmetics‚ toxicology‚ and psychology research where animals are used in any part of an experiment. An animal could sensibly be defined as vertebrates. With this exception of cephalopods‚ no invertebrates have any legal standing in any country so far as I am aware‚ and it would be hard to construct a case for any invertebrates having moral rights.
