The karyotype of a young child who is affected with familial Down syndrome revealed a total of 46 chromosomes. An older sibling, however, who is phenotypically unaffected, has 45 chromosomes. Explain how this could happen. What would you expect to be the numbers of chromosomes in the parents of these two children?

What quantity of heat, in kJ, is required to convert 30.3 g of ethanol ($C_2H_5OH$) at 23.0 $^\circ C$ to a vapor at 90.3 $^\circ C$ (its boiling point at 1 atm is 78.3 $^\circ C$)? (specific heat capacity of $C_2H_5OH$ (l) = 2.46 J/g $\cdot$ C; specific heat capacity of $C_2H_5OH$ (g) = 1.42 J/g $\cdot$ C; $\Delta H_{vap}$ = 39.3 kJ/mol)

If I had to say one thing that describes the content of this course, I would say that it's "all about the standard deviation of a sample and how it can be used to understand one or more sample data sets and the populations that were sampled". Having made this statement, please criticize it with your own perspective and you may agree (you must justify why!), disagree (again justify why) or wish to put your own spin on it to be more specific.
13. There are two major department stores at the mall: Sears and JC Penny. They both benefit from the mall security patrol. Assume that the quantity of the mall patrol is Q units and that we can write down the marginal benefits and the total benefits provided by mall security for each store as: Sears: MPB_sears = 5 - 0.5Q Total Benefit_sears = 5Q - 0.25Q2 JC penny: MPB_JC = 2 - 0.25Q Total Benefit_JC = 2Q - 0.125Q2 The marginal cost of hiring one additional unit of mall patrol is always $4. That is MC = 4. Answer the following questions: a. Assume Sears is the first department store in the mall. How many units of mall patrol will Sears choose to hire? What is the net benefit (its total benefit minus its total cost) to Sears of hiring this amount of mall security? b. Now JC Penny opens a store in the mall. Notice that the mall security patrols that Sears hired also benefit JC Penny. That is both stores can consume this mall security: mall security is not rival and also is not excludable (JC Penny can benefit from the mall security even when it does not pay for any mall security). Now, that JC Penny is in business at the mall, does JC Penny want to hire any more units of mall security patrols? Explain your answer. What is JC Penny's net benefit after its decision? c. Now the leasing manager for the mall is in charge of determining how many mall security units should be hired. The manager will make her decision based upon the total marginal benefits of hiring mall security units. How many units of mall security will she hire? Explain your answer. d. Suppose the manager charges Sears $3 per unit of mall security patrols and charges JC Penny $1 dollar per unit of mall security patrols. Will the two stores both accept this price? e. What is the net benefit to the manager of hiring the amount of mall security patrols on the basis of the total marginal benefits of these patrols? What's the net benefit for both of these two department stores? How does your result compare with parts (a) and (b)?
Question5-2 A 3 g particle carrying a charge of 76 $\mu C$ enters a uniform 4 T magnetic field at a speed of 27 $\frac{m}{s}$ and with an angle of 41° with respect to the field lines, as shown in the figure. For each of the following statements, determine whether it is true or false. The particle follows a circular path as the force is normal to the velocity. The work done by the field on the particle is zero as the force is normal to the displacement. The particle's speed varies as it passes through the B-Field. The force on the particle is in the +x direction. The x-component of the particle's velocity is unchanged as it passes through the B-Field.
Example Prepare any journal entries based on the following data regarding the bank reconciliation prepared by Corruption Company on July 31, 2017. 1. A customer's cheque for $260 was returned with the bank statement and stamped NSF. 2. Outstanding cheques amount to $650. 3. Service charges for July per bank statement are $25. 4. Cheque #925 for $3,250 for office equipment was erroneously recorded by the bookkeeper as $2,350. 5. The bank erroneously credited Corruption Company's account for a $575 deposit made by Bribe and Bilk Inc. 6. A deposit ticket correctly prepared for $695 appeared on the bank statement as a deposit for $965. 7. Cheque #930 for $900 for rent expense was erroneously recorded by the bookkeeper as $90.
