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

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

In biology species can become isolated from other species through a number of processes. These isolation processes keep the two species from interbreeding and producing hybrid offspring. There are five separate isolation processes that prevent two species capable of producing offspring from being able to do so. Ecological Isolation Ecological‚ or habitat‚ isolation is when two species that could interbreed do not because the species live in different areas. For example‚ in the wild of India both

Lab 12: Meiosis kimberleigh Lewis Biology 1408-63400 Consider the Concepts Experiment: 1. A common misconception about meiosis appears when students identify which of the two divisions converts a diploid cell into two haploid cells. Meiosis I is the division immediately following DNA replication and replication does not occur again before meiosis II. However‚ meiosis I is the "reduction" division when a diploid cell forms two haploid cells. If the DNA duplicated before meiosis I‚ how
