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

The main branches of science (also referred to as "sciences"‚ "scientific fields"‚ or "scientific disciplines") are commonly divided into two major groups: social sciences‚ which study human behavior and societies‚ and natural sciences‚ which study natural phenomena (including fundamental forces and biological life). These groupings are empirical sciences‚ which means the knowledge must be based on observable phenomena and be capable of being tested for its validity by other researchers working under

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

in genetics A geneticist is one who studies and works to apply his/her knowledge of genetics‚ branch of biological sciences that involves heredity and natural point of views in living organisms. Geneticists are the leader of the last frontier of biology‚ they have u the lnlocked last few secrets of life Genetics more focuses on the passages of traits form parents to their offspring from generation‚ to generation‚ though this is far from the only area of interest. Some geneticist works can work in

The sources of genetic variation such as mutations and sexual recombination will also be reviewed. Mechanisms of Evolution It is said that biology “came of age” when Charles Darwin published “On the Origin of Species by Means of Natural Selection”. In this book Darwin expressed his concept on the mechanism of evolution: natural selection. He felt that a population could change over generations

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
