effect him for the rest of his adult life. Through the characterization of Sammy‚ Updike employs a simple heroic gesture to teach us that all of our actions have consequences wand we are all responsible for our own actions. In the short story "A&P" author John Updike describes the setting and customers with great detail‚ while letting the reader make their own assumptions on Sammy’s exact motivations for quitting his job. The ending of the story leaves you to draw your own conclusions of what

Biology 1010 is a course that introduces students to the basic biological phenomena in all living organisms. It focuses on the different molecular levels of organization‚ heredity in evolution‚ genetics and reproduction. Through this course‚ I was able to master three essential concepts such as Mendel’s Law of Segregation‚ enzymes‚ and photosynthesis. Gregor Mendel was an Augustinian monk that argued that parental traits are passed on to their offspring discrete “heritable factors”. Heritable factors

Exercise 1: Dissolved oxygen is oxygen that is trapped in a fluid‚ such as water. Since virtually every living organism requires oxygen to survive‚ it is a necessary component of water systems such as streams‚ lakes and rivers in order to support aquatic life. The dissolved oxygen is measure in units of ppm—or parts per million. Examine the data in Table 2 showing the amount of dissolved oxygen present and the number of fish observed in the body of water the sample was taken from; finally‚ answer

Figure 1: The reaction rates of enzyme-catalysed reactions of hydrogen peroxide into diluted water depending of the varying percentage concentrations of catalase. Mean rates (±SE) of 5 separate experiments (n=5) are shown. Line of best fit (y = 0.0002x + 0.0038 R² = 0.9154) is presented using the trend line function in Excel.

Thin film of liquid surrounding soil particle -> dilute solution of mineral salts • Cell sap in root hair -> lower water potential than surrounding soil solution -> separated by partially permeable membrane • Water enter root hair cell by osmosis/active transport • Mineral salts -> diffusion and active transport [pic] How is the structure of root hair cell adapted to its function of absorption? • Elongated protrusion that increases surface area to volume ratio -> increase efficiency

References: Discussion Discussion If the succinate is broken‚ then the DPIP will become colorless faster. As shown by the data in Table 2 and Figure 1 above‚ the transmittance level increased time after time from 0 minute to 30 minutes. It means that both sodium fluoride and malonate inhibited the activity of the enzyme succinate dehydrogenase in the reaction to convert succinate to fumarate. They

“A&P” The story “A&P” gives us a interesting‚ dynamic protagonist. We are given a short situation in which to determine his personality and his intentions. As the story progresses‚ we get a peek of Sammy’s personality‚ but his reasons are still a blur. Several other characters assist to contrast against Sammy. Though the story is short‚ we are left with a question to ask ourselves‚ why did Sammy do what he did? From the beginning of the story Updike uses Sammy’s youth and unromantic descriptive
