Lauren Spillers Biology 1408 February 5‚ 2013 Lung Cancer Lung cancer is the number one form of deadly cancer in the United States. It is not only something that can kill you but also can put a strain on you and your family financially‚ emotionally‚ and medically. Lung cancer is formed when the cells of the lungs grow in an uncontrolled way‚ this creates a lump or a tumor which can either be malignant (cancerous) or benign (not cancerous). Radon gases‚ smoking‚ and second hand smoke cause lung

DEFINITIONS * Biology is a natural science concerned with the study of life and living organisms‚ including their structure‚ function‚ growth‚ evolution‚ distribution‚ and taxonomy. * The cell is the basic structural and functional unit of all known living organisms. It is the smallest unit of life that is classified as a living thing (except virus‚ which consists only from DNA/RNA covered by protein and lipids)‚ and is often called the building block of life. Organisms can be classified

Experiments investigating the effect of a particular factor on an enzyme-catalysed reaction are commonly used as assessed practicals in Biology. The reason for this is there are a number of factors that can be investigated‚ and therefore‚ a number of factors that can also be controlled. From our lecture‚ we are aware that the following can affect the rate of reaction: 1) Temperature: a. Independent variable: A range of temperatures should be investigated‚ with particular attention

rerio are used for developmental research. (4 marks) Organisms | Advantages | Disadvantages | A. thaliana used for plant development research | 1.) Tiny Genome- Therefore it is easy to study the genes and also to manipulate the genes.2.) Short Life Cycle- Experiments conducted on the A.thaliana will have observable results fast as the development of the plant is rapid.3.) Small size-can be cultivated in a tiny space and this is vital because research areas usually have space limitations.4.)
