arise from one single cell (Madigan et al.‚ 2015). In bacteria such as Vibrio natriegens‚ who are curved-rod shaped microorganisms‚ they elongate to almost twice their own size and form a dividing wall in which splits the single cell into two daughter cells (Madigan et al.‚ 2015). There are four phases to bacterial cell growth: the lag phase‚ which is a period where bacteria are maturing and adjusting to the environment. During this phase‚ RNA synthesis‚ production of ribosomes‚ enzymes and other

Introduction There are a number of factors that can contribute to the growth of a population and these trends can be seen in a number of species. It is generally believed‚ from an ecological perspective‚ that populations will display either an exponential of logistic growth rate. If optimal environments are consistently maintained with no biotic or abiotic limiting factors (excess food‚ excess space availability‚ optimum climactic environment‚ no predation‚ etc) then a population will grow in
