Biology is a natural science concerned with the study of life and living organisms‚ including their structure‚ function‚ growth‚ evolution‚ distribution‚ and taxonomy.[1] Modern biology is a vast and eclectic field‚ composed of many branches and subdisciplines. However‚ despite the broad scope of biology‚ there are certain general and unifying concepts within it which govern all study and research‚ consolidating it into single‚ coherent field. Biology generally recognizes the cell as the basic unit

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

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

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

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

Abstract The human body needs to maintain proper homeostasis to survive. There are several different organ systems in the human body. Two of those systems are the digestive system and the urinary system. Both systems remove waste from the body but in an entirely different way. They also maintain homeostasis within our blood stream. Both systems are critical for survival. This paper will describe how each of those systems works on its own and also how they work together to maintain homeostasis
