the products water and oxygen. To observe this catalase activity I used small amounts of liver samples slightly smaller than the size of a pea to see the reaction when hydrogen peroxide is added to it. In this experiment I exposed the liver samples in three different temperature environments: 3°c‚ 22°c‚ and 75°c. I wanted to measure how much water and oxygen is produced in each environment by measuring the visible bubbles in each test tube. I predicted that water and oxygen production would occur

Anatomy of the Respiratory System Nose and Nasal Cavity The nose and nasal cavity form the main external opening for the respiratory system and are the first section of the body’s airway—the respiratory tract through which air moves. The nose is a structure of the face made of cartilage‚ bone‚ muscle‚ and skin that supports and protects the anterior portion of the nasal cavity. The nasal cavity is a hollow space within the nose and skull that is lined with hairs and mucus membrane. The function

nearby soil in its roots. The leaves then take light energy from the Sun‚ which is absorbed in the chlorophyll in the cells and passes it along for it to be used in photosynthesis. Glucose is produced and is converted into Starch to be stored. Oxygen is produced from the water and it is a waste product so it is released into the air. The plant uses Carbon Dioxide and water to create Carbohydrates.

can be made. Light intensity is one of the factors that affect the rate of photosynthesis and that is what our experiment is based on: Aim: In this experiment we shall investigate how the rate of photosynthesis (measured by the increased volume of oxygen) is affected by changes of light intensity in water plants. Hypothesis: I predict that as the intensity of light increases‚ so will the rate of photosynthesis. Furthermore‚ I hypothesise that if the light intensity increases‚ the rate of photosynthesis

of only one kind of atom. A compound is the substance that is made from the atoms of two or more elements that are chemically bonded. Water is an example of a compound because it is one of many compounds that consist of molecules. The hydrogen and oxygen molecules are chemically bonded to form a water molecule.
