Experiment 9: Growth curve of Serratia marcescens Abstract Bacteria grows by binary fission. The aim of this experiment is to follow the growth of Serratia marcescens in nutrient broth at 37oCby recording the changes in turbidity (cloudiness) by measuring the absorbance of visible light (600 nm) and also to prove that there is an increase in the cell number and not just in mass during the growth. In the experiment we measure the full growth curve of Serratia marcescens by measuring the absorbance

PERSPECTIVES ON POPULATION GROWTH Based on the current trend‚ there will be a total to about 9.2 billion people on the earth by mid-century‚ fuelled by the birth of 220000 children a day and falling mortality rates (Population Institute‚ 2014). This estimate raises questions about the future of humanity and the planet we inhabit. The debate about an optimal size for human population is one that has waged over the years. The question is fundamentally about sustainability; whether the resources that

INTRODUCTION - POPULATION GROWTH The world experienced dramatic population growth during the twentieth century‚ with the number of inhabitants doubling from 3 to 6 billion between 1960 and 2000. India‚ too‚ saw very rapid population growth during this period – from 448 million to 1.04 billion – and to 1.21 billion in 2010. The effects of past and projected future demographic change on economic growth in India is the main focus of this chapter. Figure 1 plots world population from 1950 to

suggests that demographic dynamics is the change in population in terms of size composition‚ age structure‚ and urbanization. This includes the causes and consequences of migration‚ fertility and mortality. These dynamics are different from the past since each and every country experiences changes in terms of living condition‚ number of people born and people who died in that particular time. This essay will discuss the current size of the population‚ how does it effect the economic development‚ the impact

Many people (including national leaders) worry that population growth depletes resources and can trigger social or economic catastrophe if it is not contained. As discussed in the preceding section‚ most of the projected population growth during this century will take place in developing nations.
