Temperature effects on the growth of microorganisms Introduction: The purpose of this experiment was to determine the effects that temperature has on three different organisms. Temperature is one of the most important environmental factors affecting growth and survival of microorganisms². The three organisms used where Escherichia coli‚ Pseudomonas fluorescens‚ and Bacillus stearothermophilis. Most bacteria grow within a particular temperature range. The minimum growth temperature is

By 2025‚ the share of the elderly in the population of Singapore‚ Hong Kong‚ Taiwan‚ Japan and South Korea will at least doublem and the share of the young will fall sharply. The ageing of the population will drag down the potential rate of growth as a result of the fall in volume of labor input and the decline of the domestic saving rate. Furthermore‚ it will also serve as negative effects upon fiscal conditions and households through

The Effects of Antibiotics on Bacterial Growth Biology II 1996 Bacteria are the most common and ancient microorganisms on earth. Most bacteria are microscopic‚ measuring 1 micron in length. However‚ colonies of bacteria grown in a laboratory petri dish can be seen with the unaided eye. There are many divisions and classifications of bacteria that assist in identifying them. The first two types of bacteria are archaebacteria and eubacteria. Both groups have common ancestors dating to more

About 70% of the Indian population lives in more than 550‚000 villages. The balance stays in more than 200 towns and cities. India is expected to surpass China in total population by 2030 (five years earlier than previously estimated). As per the current demographic statistics‚ India’s population is slated to rise by almost 350 million

The law of demand states that more is bought at a lower price than at a higher price. In other words‚ the law of demand postulates an inverse relationship between the price and quantity demanded of a commodity‚ all other factors affecting demand remain constant (ceteris paribus). A market demand curve
