Exponential growth

37 °C for 48 hours. This process was done on October 11th and repeated on October 18th. The growth was observed and recorded in Table 4. A sterile inoculating loop was used to quadrant streak samples of Staphylococcus epidermidis and Micrococcus luteus on agar plates. This process was done on October 11th and repeated on October 18th. The plates were incubated at 37 °C for 48 hours. The resulting growth was recorded in Table 6. A sterile inoculating loop was used to spot inoculate Escherichia…

Our world is always changing and evolving , meaning that technology and economic systems continue to evolve and advance. Factors that contribute change are technology, the environment, and changing social circumstances. The following scenarios are based upon situations humanity may face in 2050 resulting from change. The first scenario is based around an uncontrollable economy on the verge of collapse. The population at the time is over nine billion with the occurrence of global mass…

Growth in the United States One of the major reasons our economy has grown in such a large scale has not been just about one person or one factor. The US has relied on laborers, human capital and the land. Being one of the strongest economies, it has learned to use its natural resources to its advantage and has been able to create a large economy due to it. The first advantage of growth in the U.S has been its richness in land and natural resources. The United States is abundant in mineral…

Objective I. To learn how to inoculate the nutrient broth properly in preventing contamination to the nutrient broth and the culture Escherichia Coli. This is done by sterilized the loop and sterilized the neck of the tub with heat from before use and before put the cape on. II. To learn how to do a simple streak of an E. coli culture on a nutrient agar plate with one stroke from start to end like a “Z”. III. To learn how to do a complex streak where we grow E. coli culture on the nutrient…

Body-size and time have a unique relationship. Cope’s Rule explains this relationship by stating as time progress so does body-size. As an organism’s lineage ages, the general body-size becomes larger. This increase can have many benefits, but also drawbacks. Things like intelligence, development time, and fecundity are affected by body size. A study just released by Nature though might show that this rule does not always apply. A new effect is being observed that shows body-sizes may actually…

the human population and what cause it. The two revolution she attributed to it was the agricultural and industrial revolution, where there is no doubt it increased the population. There were many new technologies and ways that caused the population growth and environmental changes in the agricultural and industrial revolution. In early human societies before the idea of agricultural, humans were hunter and gathers. Hunter and gatherers would depend on wild animals and wild plants for food. This…

2. Loop (the tool): A wire made into a loop to assist in picking up inoculum from a culture of microorganisms. The loop is also used in the process of cultivating microbes by transferring inoculum for streaking. 3. Agar vs Blood Agar: a. Agar: a growth medium made with agar and other nutrients. The agar allows microorganisms such as fungi and bacteria to be cultured. b. Blood Agar: Blood agar is used for the purpose of cultivation and isolation of various strains of pathogenic bacteria. 4.…

Economic Growth Economic growth is the increase of the value of goods and services produced in an economy over a period of time, measured by changes in real GDP (Dixon & O’Mahony, 2014). Australia’s economic growth rate has been declining over recent years and is currently at 2.5% (RBA, 2015). As shown by FIG 1, overall the trend of GDP growth has gradually been declining over recent years with peaks of 4.5% in 1995 and a record low of 1.5% in 2008 (ABS, 2015) and has been forecast to continue…

Performance enhancing drugs are substances that improve an athlete’s performance. Performance enhancing drugs enlarge muscle size and increase the blood’s oxygen carrying capacity. Although the drug makes a substantial difference in athletic performance, the use of the drug can be medically dangerous. Steroids are outlawed by organizations that govern professional sports. The different substances of PED’s are stimulants, anabolic steroids and erythropoietin. Athletes take these drugs to make…

P X (1+r) ^ n, P = population = 12.628 billion (2048), r = growth rate = 1.6%, (12.628) X (1 + 0.016) ^ 45 = (12.628) (1.016) ^45 = (12.628)(2.0428) = 25.7964784 =26 billion So, the world’s population would be 25.256 or 26 billion in 2093. “2. With a world population in 2003 of 6.314 billion and a projected population growth rate of 1.1% instead (which is the United Nations’ projection for the period 2003 to 2015).” (Macroeconomics Principles…
