An individual suffers a severe cut on the arm and bacteria, which the host are never “seen” before (immunologically) infect the wound. These bacteria never live inside the host’s cells as part of their life cycle (via consumption). An immune response is initiated and after several days the bacteria are eliminated, and the wound heals. The host is now solidly immune to re – infection by this organism. In as much detail as you can describe what happened. Include all of the immune mechanisms involved in pathogen recognition, elimination, and the establishment of immunological memory.

The Fox TV network is considering replacing one of its prime-time crime investigation shows with a new family oriented comedy show. Before a final decision is made, network executives commission a sample of 400 viewers. After viewing the comedy, 250 indicated they would watch the new show suggested it replace the crime investigation show.

For an 84.5% confidence interval, what is the upper confidence limit for the proportion who prefer the new show?
Express your sollutions as the decimal equivalent of a proportion rounded to four decimal places.

QUESTION B

An ice-cream vendor on the beachfront knows from long experience that the average rate of ice-cream sales is 12 per hour. If, with two hours to go at work, she finds herself with only five ice-creams in stock, what are the probabilities that (a) She runs out before the end of the day; (b) She sells exactly what she has in stock by the end of the day without any excess demand after she sells the last one; and (c) She doesn't sell any?

The economies of China and India experienced very rapid growth. This increases their
citizens’ income and wealth. In turn, these citizens increase their savings in their country
and also in the United States.
@ When foreign savings enter the US loanable funds market, which curves if affected — supply
or demand? How is the curve affected?

@ Draw the graph of the US loanable funds market both before and after the increase in
foreign savings?

@ How does the change in foreign savings affect both investment and future output in the
US?

Please describe in detail.

A local Birmingham-area restaurant chain introduced a new summer menu in its Vestavia Hills location, but not its Mountain Brook location. Nightly revenue averaged $8,000 in Vestavia Hills and $7,000 in Mountain Brook before the menu change, but $9,500 in Vestavia Hills and $8,000 in Mountain Brook after the menu change.

a. The difference-in-difference estimate of the increase in average nightly revenue attributable to the menu change is

b. In the previous question, the increase in average nightly revenue attributable to summer, rather than the menu change, is

The following data was collected by a student performing the DETERMINING THE MOLAR ENTHALPY OF NEUTRALIZATION portion of the experiment. 50.00 mL of a 0.250 M acid is combined with 50.00 mL of 0.255 M NaOH. Before the reaction, the acid and base are at a temperature of 24.92 °C. After mixing, the neutralized solution reaches a maximum temperature of 26.50 °C in a calorimeter (Ccal=58.4 J/°C). The neutralized solution has a specific heat of 3.89 J/g°C and a density of 1.04 g/mL. What is the molar enthalpy of neutralization in kJ/mol?

You own 100 shares of a Sub Chapter​ "S" corporation. The corporation earns​ $5.00 per share before taxes. Once the corporation has paid any corporate taxes that are​ due, it will distribute the rest of its earnings to its shareholders in the form of a dividend. If the corporate tax rate is​ 21% and your personal tax rate on​ (both dividend and nonminus−​dividend) income is​ 30%, then how much money is left for you after all taxes have been​ paid?

A. ​$500

B. ​$350

C. ​$210

D. ​$300

while scouting in your rocket ship, you discover a spherical asteroid of mass 5000 kg and radius 10 m rotating with a period of 2 minutes. You fire a probe at the surface at a glancing angle of mass .5 kg with a velocity of 200 m/s. When the probe impacts the asteroid, the asteroid instantaneously shrinks down to a radius of 3m yet retains the same mass (including the probe). What is the new period of the asteroid. what is angular velocity before ad after the probe hit?

A train, A, with a mass of 19,000 kg is travelling at 90 km/h when it strikes a second train, B, which has a mass of 17,000 kg and is moving in the same direction at a speed of 43.2 km/h. If the coefficient of restitution for the collision is 0.87 and all resistances to motion are negligible, then

(i) calculate the speed of the trains A and B immediately after the impact.

(ii) as a result of damage during the collision trains A and B have a constant friction resistance to the motion of 14,500 N. Calculate the distance that the train B will move before coming to rest.
