Denaturation can occur if a protein is heated or undergoes changes in pH. Denaturation disrupts the secondary, tertiary, and quaternary structure of a protein. Would you expect the Biuret test to work on a protein that had been denatured? Why or why not?

“When a strong base is gradually added dropwise to a weak acid, the pH changes at each addition. When the appropriate quantity of base has been added to react with all of the acid, the pH changes sharply, indicating the endpoint of the titration. A plot of pH versus volume of base added gives what is known as a titration curve”.

Consider the titration of 25.00 mL of 0.1000 M benzoic acid with 0.1000 M NaOH,.

Write a balanced chemical equation for the titration reaction using C6H5COOH for benzoic acid’s formula.

Determine the volume of NaOH solution required to reach the endpoint.

The chart on the next page has entries for several steps along the titration curve. To calculate the pH at each step, you first must understand the chemistry at that step, and then you can decide the appropriate method to calculate the pH. For each volume listed, (i) list the major species in solution, (ii) determine whether the Ka equation, Kb equation, buffer equation, or solution equilibrium equation is appropriate for the calculation of the solution [H3O+] and pH, and (iii) complete the calculations.

Describe the histological changes that occur in patients with Zollinger-Ellison Syndrome. What is the etiology of the disorder? How does the etiology of this disorder differ from that of gastroesophageal reflex disease? What protective mechanisms does the tissue employ to prevent the tissue damage observed in disorders mentioned above?

12. Newton's law of cooling states that the temperature of an object changes at a rate pro-portional to the difference between its temperature and that of its surroundings. Suppose that the temperature of a cup of coffee obeys Newton's law of cooling. If the coffee has a temperature of 200F when freshly poured, and 1 min later has cooled to 190F in a room at 70F, determine when the coffee reaches a temperature of 150F.

In the first decade of this century, the global economic environment has seen tremendous changes. On the local and international scales, the fact that ‘cultural environment’ is one of the most important factors affecting organizations raises the significance of the management of cultural differences. It is crucial for businesses to understand these differences and find ways to hurdle the barriers these differences present in a socially responsible manner.

TASK:

Select any organization of your choice operating in at least two countries. Carry out a research on the following aspects and present it in the form of a Report in Word.

1. For any two chosen countries in which it operates, assess the impact of economic and cultural forces on the management styles and business outcomes of the organization.
2. For any one country chosen above, examine how the ethical and socially responsible behavior is built in the management practices and business operations.

A company claims that a new manufacturing process changes the mean amount of aluminum needed for cans and therefore changes the weight. Independent random samples of aluminum cans made by the old process and the new process are taken. The summary statistics are given below. Is their evidence the 5% significance level (or 95 confidence level) to support the claim that the mean weight for all old cans is different than the mean weight for all new cans ?Justify fully!

The old process had a sample size of 25 with a mean of 0.509 and a standard deviation of 0.019. The new process has a sample size of 25 with a mean of 0.495 and a standard deviation of 0.021.

For any Hypothesis Test make sure to state Ho, Ha, Test statistic, p-value, whether you reject Ho, and your conclusion in the words of the claim.

For any confidence interval make sure that you interpret the interval in context, in addition to using it for inference.

14) The selling prices of mutual funds change daily. In order to study these changes, a sample of mutual funds was examined and the daily changes in price are listed below.
