1. After being produced in the endoplasmic reticulum, some proteins go on to the __________ where they may undergo final modifications before being packaged to be sent along to their final destination inside or outside of the cell.

2. The cell membrane allows some molecules, such as oxygen and carbon dioxide to pass through, while preventing other molecules such as glucose and amino acids from passing through, this means cell membranes are ______________.

perfectly insulated container with no heat capacity is used to mix together the following three samples of water:

I.183.2 grams of water at 23.2 °C

II.32.1 grams of water at 14.2 °C

III.143 grams of water at an unknown temperature.

After the three samples are combined, the final temperature of the combined solutions is 39.0 °C. What is the temperature of sample III before the samples were mixed together?

Imagine that your company is switching to a matrix structure . Before, you were working in a functional structure. Now, every employee is going to report to a product/team leader (Product A, B and C) as well as a department manager (ex: Marketing, Research & Development, Production, Procurement, and Finance).

Create a list of things that need to be done after the change occurs. List and explain at least 5 things/steps to do?

Laquita deposits $5500 in her retirement account every year. If her account pays an average 6% interest and she makes 38 deposits before she retires, how much monet can she withdraw in 20 equal payments beginning one year after her last deposit? please show cash flow diagram and solve NOT with excel but with the interest rate formula equations!!!

1. VOLUME TECHNIQUE: This method is based on the volume of carbon dioxide produced and collected.
2. MASS TECHNIQUE: This method is based on the difference in mass before and after the reaction.

The mass of carbon dioxide calculated using the volume technique will not be identical to the mass of the carbon dioxide calculated using the mass technique. In this discussion, compare and contrast the two techniques and the mass of carbon dioxide obtained by each technique. Also discuss reasons for the difference in masses.

1) List the five factors that magnify the need for training.

2) Explain the potential benefits of training (Minimum 5 with detailed explanation for each)

3) Describe how to evaluate a training program before purchasing it.

4) How can ISO 9000 registration be useful to a total quality implementation?

5) List the implementation preparation steps that follow after the vision statement and broad objectives have been developed.

A battery is constructed based on the oxidation of magnesium and the reduction of Cu2+. The initial concentrations of Mg2+ and Cu2+ are 1.1×10−4 M and 1.6 M , respectively, in 1.0-liter half-cells.

PART A: What is the initial voltage of the battery?

PART B: What is the voltage of the battery after delivering 4.7 A for 8.0 h ?

PART C: How long can the battery deliver 4.7 A before going dead?

The eardrum, which transmits vibrations to the sensory organs of your ear, lies at the end of the ear canal. In adults, that ear canal is about

2.5 cm in length. We can treat the ear canal as a tube, closed by the eardrum at one end, and open to the atmosphere at the external end. Consider a fluctuating air column in the canal: similar to a vibrating†string with one fixed end. Its fundamental frequency becomes half that of a string of the same length with both ends fixed. (You can convince yourself of this by imagining a tube with one end closed and the other end open. Sketch the node and antinode of the possible fundamental mode in the tube!)

f_n = nv/4L

Use the above equation to find what frequency standing waves can occur within the ear canal that are within the range of human hearing. The speed of sound in the warm air of the ear canal is 350 m/s. The audible range is 20 Hz to 20 KHz.

a. all Hypothesis Tests must include all four steps, clearly labeled;

b. all Confidence Intervals must include all output as well as the CI itself

c. include which calculator function you used for each problem.

2. An experiment was done to see whether open-book tests make a difference. A calculus class of 48 students agreed to be randomly assigned by the draw of cards to take a quiz either by open-notes or closed-notes. The quiz consisted of 30 integration problems of varying difficulty. Students were to do as many as possible in 30 minutes. The 24 students taking the exam closed-notes got an average of 15 problems correct with a standard deviation of 2.5. The open-notes crowd got an average of 12.5 correct with a standard deviation of 3.5. Assume that the populations are approximately normal. At the 5% significance level, does this data suggest that differences exist in the mean scores between the two methods?

A portfolio manager controls $10 million in common stock. In anticipation of a stock market decline, the decision is made to hedge the portfolio using the S&P 500 futures contract. The portfolio's beta is 1.1 and the dividend yield on this portfolio is 3% annually. One S&P 500 futures contract with 90 days to settlement date is traded at 1164.50. The S&P 500 index itself is at 1150.  (Use 365 days a year)

1. Calculate the number of futures contracts that should be bought or sold. Indicate whether you should buy or sell.
2. Suppose that when the contracts are closed out, the S&P 500 index has increased to 1380. Calculate the gain or loss on the combined positions (stock portfolio and futures contracts).
3. Suppose that when the contracts are closed out, the S&P 500 index has decreased to 1035. Calculate the gain or loss on the combined positions (stock portfolio and futures contracts).
