3%‚ was diluted using 10 mL of hydrogen peroxide and 20 mL of water. In the second beaker‚ a ¼ dilution of potato extract was made using 2 mL of potato extract and 6 mL of water. The third plastic beaker contained 8 mL of water. Using the first and second beaker the experimental assay was performed. Using forceps a small paper disk was dipped into the second beaker containing the potato catalase for exactly 5 seconds. It was next dried on a paper towel for 5 seconds‚ and finally placed at the

Security gaps occur whenever there are lapses in the secure application or implementation of a company’s policies‚ protocols‚ procedures‚ and practices. Risk management helps shrink the security gap by identifying‚ assessing‚ prioritizing‚ and addressing various forms of risk. The difference between established security controls and controls needed to address all vulnerabilities is called the security gap. There are several reasons for security gaps including the following: Unintentional lack of

area of low concentration of water molecules (high concentration of dissolved particles). It is difficult to observe osmosis at the cellular level since cells are very tiny and can only be seen with a microscope‚ so you are going to use sticks of potato tissue in solutions that have different concentrations of dissolved substances to observe the effects of osmosis on living tissue. There are three basic relative concentrations of solutions. An isotonic solution has a concentration of dissolved particles

The Micro Chip Computer Corporation Shows a total of net sales for the years of 2000 – 2004. The total net sales have seemed to drop since 2000. I will compute the year-to-year percentage annual growth in total net sales by taking the current year total net sales and subtracting the previous years. I will then multiply that by 100 and then divide that by the previous year’s total net sales. This will give me the annual percentage growth. The formula will be (current year total net sales – previous
