Explain, in detail, why atomic radii do not increase uniformly with increasing atomic number. Give specific examples in your answer.

1. During a 10-year period, the standard deviation of annual returns on a portfolio you are analyzing was 15 percent a year. You want to see whether this record is sufficient evidence to support the conclusion that the portfolio’s underling variance of return was less than 400, the return variance of the portfolio’s benchmark.

1. Formulate null and alternative hypotheses consistent with the verbal description of or objective.

2. Identify the test statistics for conducting a test of the hypothesis in part A

3. Identify the rejection point or point at the 0.05 significance level for the hypothesis tested in Part A

4. Determine whether the null hypothesis is rejected or not rejected at the 0.05 level of significance.

A firm that purchases electricity from the local utility is considering installing a steam generator. A large generator costs $300,000 whereas a small generator costs $240,000. The cost of operating the generator would be $100,000 per year for the large and $135,000 for the small. Either generator will last for five years. The cost of capital is 9%. For each generator option, assume immediate installation, with purchase and operating costs in the current year and operating costs continuing for the next four years. Assume payments under both options at the start of each year (i.e., immediate, one year from now,..., four years from now). What is the net present value of the more attractive generator? Please round your answer to the nearest dollar. Report the NPV of cost as a negative number.

1. Metblastine, a drug that inhibits microtubule function, is used to treat some forms of cancer. Hypothesize what cellular processes would be affected in cancer cells that are given Metblastine.
2. A mutation in the occludin gene, a tight junction protein, results in severe impairment of intestinal function, resulting in malnutrition and immune disorders. Knowing what you do about the function of tight junctions from class, propose the likely cause of the above disorders (think leaky small intestines). How might the loss of tight junctions impact the selective permeability of the intestinal cells?
3. For a protein to be an integral membrane protein, it would have to be amphipathic, with at least one hydrophobic region. Explain how a protein such as an aquaporin would interact with the surrounding phospholipid bilayer and the surrounding aqueous environment.
4. Describe the mechanism by which glucose and sodium ions are co-transported from the digestive tract into the intestinal cells of an animal? Assume that the intestinal cells already have intracellular glucose.

A sample of butane gas, C4H10, was slowly heated at constant pressure of .80 bar. The volume of the gas was measured a series of different temperatures and plot of volume vs. temperature was constructed. The slope of the line was .0208 L/K. What was the mass of the sample of butane? Please explain.

A 55.0 mL solution of 0.126 M potassium alaninate (H2NC2H5CO2K) is titrated with 0.126 M HCl.

A parallel plate capacitor with plate area 100.0cm² and air-gap separation .500mm is connected to a 12.0 V battery, and fully charged. The batter is then disconnected.

A.) The plates are now pulled to a separation of 1.00mm. What is the magnitude of the charge on each capacitor plate and the magnitude of the E-field between the plates now? ( ?₀ = 8.85 x 10^-12 C²/Nm²)

B.) What is the potential difference across the plates now?

C.) How much work was required to pull the plates to their new separation?

D.) If a proton was released from the + plate and hit the - plate, what speed would it have?
