Potassium Chloride And The Molecules Through Semipermeable...

Potassium Iodide Binds to Polysaccharide Molecules through Semipermeable Membrane Introduction: Diffusion is defined at the net movement of molecular substances from an area of high concentration to an area of low concentration. Beyond that, diffusion can further be divided into two different kinds of net movement of substance to opposing concentration gradients, dialysis and osmosis. Dialysis is defined as the separation of small molecules from large molecules as they pass through a semipermeable membrane (Koerner, 1992). When talking about dialysis, it is most often associated with the function or failure of the kidneys ability to process and rid the body of toxins from the blood. It would prove to be fatal if the kidneys failed to remove the roughly 1,500 liters of waste building up in the body (Nordqvist, 2015). This experiment mimics the nature of a selective plasma membrane and with time, monitors to passing of substances in and out of the barrier. The end results should appear to show a color changing chemical reaction within the more concentrated tube of 15%glucose/1%starch solution. Initially the clear and milky appearance should transform into a black and deep purple hue from the attachment of iodine to the sugar solution. The experiment has been conducted previously yielding various results. External factors affecting the rate of diffusion play a part in this experiment. Heat due to its influence on the thermodynamics of the molecular substances.

Active transport is the movement of fluid from lower concentration to higher concentration, it requires the use of cellular energy to move up the concentration gradient. Active transport happens through endocytosis, exocytosis, and sodium-potassium pump.

Case Problem 2: The Motion Picture Industry This case provides the student with the opportunity to use numerical measures to continue the analysis of the motion picture industry data first presented in Chapter 2. Developing and interpreting descriptive statistics such as the mean, median, standard deviation and range are emphasized. Five-number summaries and the identification of outliers are also of interest. We will write a custom essay sample on Motion Picture Industry or any similar topic only for you Order Now Interpretations and insights can vary. We illustrate some below. Descriptive Statistics Variable N Mean SE Mean StDev Range Opening Gross 100 9. 8 1. 89 18. 87 108. 43 Total Gross 100 33. 04 6. 32 63. 16 380. 15 Number of Theaters 100 1278 138 1379 3905 Weeks in Top 60 100 8. 680 0. 639 6. 390 26. 000 Variable MinimumQ1 Median Q3 Maximum Opening Gross 0. 0100 0. 0625 0. 395 12. 49 108. 44 Total Gross 0. 0300 0. 375 5. 854 47. 69 380. 18 Number of Theaters 5. 00 45. 3 410 2732 3910 Weeks in Top 60 1. 000 3. 000 7. 00 13. 000 27. 000 Interpretation Opening Weekend Gross Sales. The mean opening weekend gross sales is $9. 38 million. The five-number summary is . 01, . 0625, . 395, 12. 49 and 108. 44. Thus the opening weekend gross sales is highly variable and ranges from a low of $10,000 to a high of $108. 44 million. 50% of the motion pictures had an opening weekend gross sales of $395,000 or less, and 25% had a relatively low opening weekend gross sales of $62,500 or less. The top 25% of the motion pictures had an opening weekend gross sales of $12. 9 million or more. Total Gross Sales. The mean total gross sales is $33. 04 million. The five-number summary is . 03, . 375, 5. 854, 47. 69 and 380. 18. Thus the total gross sales is also highly variable and ranges from a low of $30,000 to a high of $380. 18 million. 50% of the motion pictures had a total gross sales of $5. 854 million or less, and 25% had a relatively low total gross sales of $375,000 or less. The top 25% of the motion pictures had total gross sales of $47. 69 million or more. Number of Theaters. The mean number of theaters for motion pictures is 1278 theaters. The five-number summary is 5, 45. 3, 410, 2732 and 3910. Thus the number of theaters for a motion picture is also highly variable and ranges from a low of 5 theaters to a high of 3910 theaters. 50% of the motion pictures were shown in 410 or fewer theaters. 25% of the motion pictures were shown in 45 or fewer theaters. The top 25% of the motion pictures were shown in 2732 or more theaters. Number of Weeks in Top 60. The mean number of weeks in the top 60 for motion pictures is 8. 8 weeks. The five-number summary is 1, 3, 7, 13 and 27. Thus the number of weeks in the top 60 is also highly variable and ranges from a low of 1 week to a high of 27 weeks. 50% of the motion pictures were on the top 60 list for 7 or fewer weeks. 25% of the motion pictures were on the top 60 list for 3 or fewer weeks. The top 25% of the motion pictures were on the top 60 list for 13 or more weeks. General Observations. The data show that there is a wide variation in the performance of motion pictures for the four variables being studied. Motion pictures range from the low gross sales movies shown in relatively few theaters to the highly successful motion pictures with hundreds of millions in gross sales and playing in almost 4000 theaters. The profiles of motion pictures using the means and medians are shown below. |Profile |Mean |Median | |Opening Weekend Gross Sales |$ 9. 38 million |$ . 395 million | |Total Gross Sales |$33. 04 million |$ 5. 54 million | |Number of Theaters |1278 |410 | |Number of Weeks in Top 60 |8. 68 |7 | The relatively few extremely high performance blockbuster motion pictures tend to inflate the mean in the above profile calculations. The profile based the median gives a better picture of the middle or more typical performance characteristics in the motion picture industry. Outliers We will use outliers to identify the highly successful blockbuster motion pictures in the data set. Using Q3 + 1. 5(IQR) to identify the levels required to qualify as a high performance outlier, we have the following. Opening Weekend Gross Sales Q3 + 1. 5(IQR) = 12. 49 + 1. 5(12. 49 – . 0625) = $31. 13 million Total Gross Sales Q3 + 1. 5(IQR) = 47. 69 + 1. 5(47. 69 – . 375) = $118. 66 million Number of Theaters Q3 + 1. 5(IQR) = 2732 + 1. 5(2732 – 45. 3) = 6762 theaters Number of Weeks on the Top 60 List Q3 + 1. 5(IQR) = 13 + 1. 5(13 – 3) = 28 weeks There are no outliers in terms of the number of theaters or the number of weeks on the top 60 list. There were motion pictures that were high on these two variables, but not high enough to be considered outliers. However, there were six motion pictures that out performed the other motion pictures in terms of reaching outlier levels in opening weekend gross sales and total gross sales. These motions pictures are considered the â€Å"blockbuster† motion pictures in the data set. To be in this category the motion picture had an opening weekend gross sales greater than $31. 13 million and a total gross sales greater than $118. 66 millions. The six blockbuster motion pictures in this category ranked by total gross sales are as follows: |Motion Picture |Opening Gross Sales |Total |Number of |Weeks in Top 60| | |($ millions) |Gross Sales |Theaters | | | | |($ millions) | | | |Star Wars: Episode III |108. 4 |380. 18 |3,663 |19 | |Harry Potter and the Goblet of Fire |102. 69 |287. 18 |3,858 |13 | |War of the Worlds | 77. 06 |234. 21 |3,910 |19 | |Wedding Crashers | 33. 90 |209. 22 |3,131 |23 | |Batman Begins | 48. 5 |205. 28 |3,858 |18 | |Mr. and Mrs. Smith | 50. 34 |186. 22 |3,451 |21 | Star Wars: Episode III was the top motion picture in terms of both opening weekend gross sales and total gross sales for 2005. War of the Worlds was shown in the most theaters 3910 and Wedding Crashers, at 23 weeks, was the motion picture in this group with the longest run in the top 60 list.

Effective Crisis Management Techniques free essay sample

This paper examines how an organization can handle a crisis. The steps an organization takes during a crisis will determine how they come out of it. This paper lays out how an organization can effectively deal with crisis to prevent lasting damage. This paper looks at the importance of a companys crisis management strategy and how the strategy that an organization takes during a crisis can affect the long-term health of that organization. It also puts forth the theory that organizations often collapse because when a crisis occurs they are not equipped to deal with it in a quick and timely fashion. From the paper: Planning ahead of time can help soften the negative impact of an ongoing crisis. Decisions made while planning for a potential crisis tend to be more rational then a decision made in the middle of a crisis. Develop a crisis manual that is simple and easy to read and make sure it is used; it is worthless if it sits idle on a shelf.
