In many opinions‚ invasive species becoming introduced to a different environment is not deemed acceptable. With many situations incorporating these species‚ they are sought to be pests‚ only trying to make lives difficult for others. Many also have come to believe‚ from experience‚ that these insidious species cause harm to the environment of which they are newly exposed to. The businesses and/or government agencies that bring invasive species to a new environment must consider many measures

of new species. Since the development of modern genetics in the 1940s‚ evolution has been defined more specifically as a change in the frequency of alleles in a population from one generation to the next. Darwin ’s theory of evolution describes the descent of all living organisms from a common ancestor. Natural Selection is the principal mechanism that causes evolution. In common parlance the word "evolution" is often used as a shorthand for both the modern theory that all extant species share a

EXPERIMENT 5 REDOX TITRATION: TITRATION USING SODIUM THIOSULPHATE Objectives 1. 2. To prepare a standard solution of potassium iodate for use to determine the concentration of sodium thiosulphate solution accurately. To acquire the proper techniques of carrying out a titration. Introduction Redox titrations using sodium thiosulphate as a reducing agent is known as iodometric titration since it is used specifically to titrate iodine. The reaction involved is: I2 + 2Na2S2O3 I2 + 2S2O322NaI + Na2S4O6
