E. coli cells are growing in a medium containing lactose but no glucose. Indicate whether each of the following changes or conditions would increase, decrease, or not change the expression of the lac operon. For full credit, you must explain your answer. It may be helpful to draw a model depicting what is happening in each situation.

(a) Addition of a high concentration of glucose

(b) A mutation that prevents dissociation of the Lac repressor from the operator

(c) A mutation that completely inactivates ?-galactosidase

(d) A mutation that completely inactivates galactoside permease

(e) A mutation that prevents binding of CRP to its binding site near the lac promoter

King Leopold Prawn Farming Ltd plans to raise $3 million to build a new prawn farm near Broome in Western Australia. It will issue bonds with a term to maturity of 15 years. The face value per bond will be $1,000 and the coupon rate will be 8% per annum, paid semi-annually. Similar corporate bonds are trading at a yield to maturity of 10% per annum, compounded semi-annually. It is expected that these new bonds will trade at this rate. How many bonds will the company need to issue?

Select one:

a. 3,598

b. 3,545

c. 3,597

d. 3,544

Draw the structure of four benzoic acid molecules and as many water molecules as you need to illustrate how the solid state of benzoic acid might look in cold water prior to recrystallization. In a second drawing illustrate what happens if the water is heated to near 100C, where benzoic acid is soluble. In each drawing identify, by name, specific examples of types of intermolecular interactions involved. Based on your drawings explain why benzoic acid is soluble in hot water and not soluble in cold water. Answer the question at the molecular level discussing the specific interactions involved in your drawings.

-JavaScript task,  just need the layout, I will fill out the citations and details and aparagraphs.

The undrained strength of a clay is 1.2 kips/ft2 , the water table in 4 ft below the ground surface, the total unit weight of the clay is 118 lb/ft3 , and a round shallow foundations with a diameter of 4.25 ft is placed at a depth of 10 ft supports a column load. a. Use a factor of safety of 2.8 and compute the safe column load on the foundation. b. An excavation near the drilled shaft removes the soil down to the water table. What is the effect on the factor of safety? (Hint consider what the physical meaning of the components in the Hansen equation. Which component is impacted by the excavation?)

(Please answer the question based on the movie "The Big Short.". Thank you.)

1.From the movie, what were the major reasons for the 2008 Great Recession?

2. One character specifically blamed a lot of the issues on “big banks”. Do you believe that the big banks are completely responsible for the near economic collapse? Why or why not?

3. What is something that you can personally take away from this movie?

4. What do you think might be the next issue in our economy (not related to COVID 19)?

5. Who was your favorite character and why?

-Suppose you are the owner of a large portfolio of long-term bonds in the health care industry and you believe that in the next three years, all healthcare will be socialized to the public sector. You anticipate that the profits of most healthcare companies will suffer immensely from this new path. If the market agrees with your assessment of the future, what would you anticipate would be the near term consequences for your bond portfolio? Why would this happen and why now, when the change to socialized medicine is three years away? How could you use options on these bonds to guard against lose?

Common terns hover in a stationary position over the ocean watching for a tasty fish. When they see one, they immediately stop their wings and simply free-fall into the ocean to catch the fish. Calculate how long a fish near the surface has to move away after the instant a tern sees it from a height of 3 m above the surface. Repeat Problem above, but now include air resistance. Assume a ball of 3 cm radius with an average density of 4400 kg/m 3 , a density of air of 1.3 kg/m 3 , and a value of C = 1.
