\Match the following descriptions with the corresponding amino acids:

This amino acid is responsible for the strength of rhino horns and wood lignin due to the strong hydrophobic interactions between them.

Subtle decreases in the serum pH lead to the protonation of this amino acid, which promotes O2 release from hemoglobin.

This amino acid is the nucleophile chymotrypsin uses to attack peptide bonds.

This amino acid disrupts α-helices because it makes the nearby protein backbone too flexible (and prevents proper hydrogen bonding).

This amino acid is believed by some to make you sleepy because it can be converted by our body into serotonin and melatonin.

This amino acid gives the titration curve shown below and it is not arginine.

The phosphorylation of this amino acid often signals for cells to grow and divide (its permanent phosphorylation could contribute to cancer).

This amino acid is added to food as a flavor enhancer because it excites neurons.

The hydroxylated version of this amino acid is essential to collagen synthesis. This amino acid forms disulfide bonds.

Students often have trouble distinguishing between adverse selection and moral hazard. Both concepts are rooted in asymmetric information among different parties in a transaction or contract. Both contribute to risk and these risks arise from a specific source – asymmetric information

In this week’s forum, I would like you to engage with each other to clarify your understanding of these concepts.

Discuss the prevalence of asymmetric information in insurance contracts, in lending, in investment…

Discuss adverse selection. Any examples.

Discuss moral hazard. Any examples?

How are the two different?

When you apply at a financial institution for a loan, you asked to fill out extensive loan applications, provide detailed financial information, provide loan collateral, etc. In addition, you may find that the money is dispensed to you as you meet certain performance criteria (example, as in a construction loan). Discuss how the loan approval and distribution process reduce risks to the financial institution associated with both adverse selection and moral hazard.

Stop and Shop grocery shops Incorporation study showed that 50% of all customers will return to the same grocery shop. Suppose six customers are selected at random, what is the probability that:

(a) Exactly two customers will return?

(b) All six customers will return?

(c) At least five customers will return?

(d) At least one customer will return?

(e) How many customers would be expected to return to the same store?

A researcher is interested to learn if there is a linear relationship between the hours in a week spent exercising and a person’s life satisfaction. The researchers collected the following data from a random sample, which included the number of hours spent exercising in a week and a ranking of life satisfaction from 1 to 10 ( 1 being the lowest and 10 the highest).

Find the mean hours of exercise per week by the participants.

Find the variance of the hours of exercise per week by the participants.

Determine if there is a linear relationship between the hours of exercise per week and the life satisfaction by using the correlation coefficient.

Describe the amount of variation in the life satisfaction ranking that is due to the relationship between the hours of exercise per week and the life satisfaction.

Develop a model of the linear relationship using the regression line formula.

Insomnia has become an epidemic in the United States. Much research has been done in the development of new pharmaceuticals to aide those who suffer from insomnia. Alternatives to the pharmaceuticals are being sought by sufferers. A new relaxation technique has been tested to see if it is effective in treating the disorder. Sixty insomnia sufferers between the ages of 18 to 40 with no underlying health conditions volunteered to participate in a clinical trial. They were randomly assigned to either receive the relaxation treatment or a proven pharmaceutical treatment. Thirty were assigned to each group. The amount of time it took each of them to fall asleep was measured and recorded. The data is shown below. Use the appropriate t-test to determine if the relaxation treatment is more effective than the pharmaceutical treatment at a level of significance of 0.05.

A researcher is interested to learn if there is a relationship between the level of interaction a women in her 20s has with her mother and her life satisfaction ranking. Below is a list of women who fit into each of four level of interaction. Conduct a One-Way ANOVA on the data to determine if a relationship exists.

Is there a relationship between handedness and gender? A researcher collected the following data in hopes of discovering if handedness and gender are independent (Ambidextrous individuals were excluded from the study). Use the Chi-Square test for independence to explore this at a level of significance of 0.05.

A researcher is interested in studying the effect that the amount of fat in the diet and amount of exercise has on the mental acuity of middle-aged women. The researcher used three different treatment levels for the diet and two levels for the exercise. The results of the acuity test for the subjects in the different treatment levels are shown below.

Sara sells two types of cakes from home. The total fixed cost for every month is budgeted at 200 BD. The labor cost per unit is equal to 2 BD. Sara sells 150 cake every month. The selling prices is 15 BD. The ingredient cost is 4 BD per cake.
Sara wants to know what price she must charge to generate enough revenue to cover her costs. With Break-Even Analysis, Sara can compare different pricing options and calculate how many units sold will lead to profitability. She needs to calculate the contribution margin which equal to selling price minus the variable costs. Contribution margin shows the revenue earned per unit, after deducting variable costs and needs to be enough to cover the company's fixed costs. Sara needs to calculate the following:

1) Break-Even Price, to determine the price needs to be set to generate enough revenue to cover her costs. Break-Even Price equal to 1 / ((1 - Total Variable Costs Percent per Unit) * (Total Fixed Costs per Unit)). Where Variable Costs Percent per Unit = Total Variable Costs / (Total Variable + Total Fixed Costs). Then determine how changes in unit sold and cost per unit affect Break-Even Price, unit sold between 100 and 200 in 10 increments and Cost per unit between 3.5 and 6.5 in 0.5 increments.

2) Break-Even Units Sold, to determine the number of units that need to be sold to achieve the break-even point. To calculate the Break-Even Units Sold, we divide the total fixed costs by the contribution margin for each unit sold. Then determine how changes in unit sold and cost per unit affect Break-Even Unit, price between 7 and 17 in 1 increments and Cost per unit between 3.5 and 6.5 in 0.5 increments

I need it to be solved using modeling , sensitivity analysis and financial excel functions with excel or written.
