Bacterial growth is the division of one bacterium into two daughter cells in a process called binary fission. Providing no mutational event occurs the resulting daughter cells are genetically identical to the original cell. Hence‚ "local doubling" of the bacterial population occurs. Both daughter cells from the division do not necessarily survive. However‚ if the number surviving exceeds unity on average‚ the bacterial population undergoes exponential growth. The measurement of an exponential bacterial

"It took until after 1800‚ virtually all of human history‚ for our population to reach 1 billion. Yet we reached 2 billion by 1930‚ and 3 billion in just 30 more years‚ in 1960" (Withgott & Brennan‚ 218). Today the world ’s population has grown to an estimated 6.5 billion people. "Increased population intensifies impact on the environment as more individuals take up space‚ use

Population Growth 5 Problem and solution essay. Have you ever thought what will happen with us in our nearest future? Is there will be better life than today? When I first saw headlines such as “Better life is coming” or “Future without problems‚ it’s true”‚ I was tempted to answer‚ “Yes”. However‚ these facts aren’t so widely reported in the newspaper and television. But the nearest future‚ in fact‚ is not as fluffy as it seems to be. Moreover‚ there will more global problems than we have. The

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 an exponential direction. Species with high
