the length of exposure to the agent ‚ the number of microorganism present and the material bearing the microorganism . Bacterial growth can be controlled by chemical agents such as: sterilization in which we kill all living organisms. Disinfection‚ decontamination‚ disinfectant‚ antiseptic‚ sanitizer and antibiotic are another chemical agents that can used to affect on bacterial growth. Chemical methods involve the application of specific chemical agents which inhibit growth or kill microbes on

of the specialized underlying structures of these life-forms. In order for us to appreciate these special adaptation‚ we first need to know how a typical plant or an animal cell organelle behaves in different water and solute concentrations. In this lab‚ we will determine the effects of hypertonic‚ isotonic and hypotonic solutions on plant and animal cells. In general when an animals cell’s placed in hypertonic solution it shrivels; a plant cell on the other hand undergoes plasmolysis. When an animal

The Transformation of Justice A cycle of murder and death spurs from the curse on the House of Atreus in Aeschylus’ The Oresteia but transforms from justice as vengeance to justice as fairness and forgiveness through the wisdom of Athena‚ establishing a new cycle of growth and life. The curse upon the House of Atreus was brought forth through the event of Zeus’ eagles devouring a pregnant hare which angered Artemis for she is the goddess of young animals and creatures.

Bacterial Transformation Lab Report Backround: The plasmid pGLO contains an antibiotic-resistance gene‚ ampR‚ and the GFP gene is regulated by the control region of the ara operon. Ampicillin is an antibiotic that kills E. coli‚ so if E. coli‚ so if E. coli cells contain the ampicillin-resistance gene‚ the cells can survive exposure to ampicillin since the ampicillin-resistance gene encodes an enzyme that inactivates the antibiotic. Thus‚ transformed E. coli cells containing ampicillin-resistance

These were changed throughout the experiment to compare different effects of cleaners towards bacterial growth. A dependent variable is the factor in which is being measured and observed. In this case‚ the zone of inhibition was measured which was used to determine the area and percentage of the bacteria growth. Constant variables are the factors

Ge’s Two Decade Transformation Jack Welch’s Leadership Change Management GE’s Two Decade Transformation: Jack Welch’s Leadership Answer 1 In April 1981‚ when Jack Welch became the CEO of GE‚ US was in recession. There were high interest rates. Strong dollar resulted in country’s highest unemployment rates. In this rapid changing and uncertain environment it was extremely difficult task for him to handle a conglomerate as big as GE and ensure that general confidence among the investors is not

Abstract This lab was focused on determining the optimal temperature of the enzyme amylase responsible for catabolizing starch polymers and to see how different temperatures affected the rate as well as how effectively the enzyme worked. To proceed with the experiment the group set up four different test tubes for each‚ bacteria and fungal amylase‚ and labeled them accordingly with different temperatures as well as different solutions . Then the spot plates were placed on the time and temperature

The Transformation of Colonial Virginia The English settlers of present day North America face many hardships and trials both in the New World and on the long voyage over. On the voyage over‚ there were many complication that were hard to overcome‚ but not impossible. Once they reached the New World they soon realized those were only the beginning of their much more severe problems yet to come in the near future. The first English settlers arrived in present day North Carolina in a place
