    The four forces of evolution include mutation‚ gene flow‚ genetic drift‚ and natural selection. Mutation is when there is a change occurs in a gene or chromosome structure which results in a difference in a physical or behavior trait. This trait can be carried into the next generation because the trait is contained in the gene. Gene flow is the process of genes transferring from one population to another. Genes can be transferred to different populations by migration of individuals along with the

    Cell Respiration Respiration is the process by which organisms burn food to produce energy. The starting material of cellular respiration is the sugar glucose‚ which has energy stored in its chemical bonds. You can think of glucose as a kind of cellular piece of coal: chock-full of energy‚ but useless when you want to power a stereo. Just as burning coal produces heat and energy in the form of electricity‚ the chemical processes of respiration convert the energy in glucose into usable form. Adenosine
