Minden Company manufactures a high-quality wooden birdhouse that sells for $25 per unit. Variable costs are $12 per unit, and fixed costs total $210,000. The company sold 30,000 birdhouses to customers during 2020. The president of Minden Company believes the following changes should be made in 2021: 1. the selling price of the birdhouse should be reduced by 20% 2. increase advertising by $33,000 Assume these changes are made. Calculate the number of units Minden Company must sell in 2021 in order to break-even.

5. Assume the demand for plastic surgery is price inelastic. Are the following statements true of false? Explain.
a. When the price of plastic surgery increases, the number of operations decreases.
b. The percentage change in the price of plastic surgery is less than the percentage change in quantity demanded.
c. Changes in the price of plastic surgery do not effect the number of operations.
d. Quantity demanded is quite responsive to changes in price.
e. If more plastic surgery is performed, expenditures on plastic surgery will decrease.
f. The marginal revenue of another operationis negative.

TOPIC- Write about the environmental factors that affect your behavior. This can include the effects of time, atmosphere or shopping. behavior.
Paragraph 1 will explore the week’s topic(s) and link it to how
it influences your behavior.
Paragraph 2 will describe changes in your behavior this week, and
how the behavior is changing
Paragraph 3 how you do this week? any changes and what results did you see?
(Behavior that I want to change is: I will exercise at least 4 times every week.)

Review the influence of mass extinctions on animal diversification. First, in one paragraph define the key geological periods in animal diversification associated with large-scale changes in diversity (3 marks). In the next paragraph, briefly describe any associations between mass extinctions and key geological periods, using several examples from Biol 227 (4 marks). In your final paragraph discuss the role of mass extinctions have had in animal diversification, focusing on key environmental changes and their consequences (3 marks).

Consider a CSTR where a simple first-order reaction takes place. The rate constant depends on the reactor temperature and can be given the Arrhenius equation. The reactor contents are cooled by a coolant that flows through a jacket around the reactor. Derive the dynamic model of the CSTR. i.e. the change of concentration of component A and the temperature of the reactor, assuming the flow rate and the inlet conditions are constant. You can use linearization technique for this coupled system.
Derive the transfer function relating changes in the reactor concentration to changes (C) in the coolant temperature (Tc).

You sequence the DNA of the organism, and it was normal at this location, with no mutations. You sequence the mRNA, and it was also normal. Based on your knowledge of protein translation, and any changes in the peptide that you recover, you assume that there has been some of type of change in the translational, not post-translational mechanism due to the radiation. What is/are a plausible guess to the explain the changes in the peptide recovered versus the one predicted and what type of potential change/mutation may have occurred in translation machinery to lead to this effect? Explain your logic and answer.

From the statements below regarding gas properties, select the statement that is false.
| A) | The density of a gas typically is much larger than the density of a solid or liquid. |
| B) | Unlike a solid or a liquid, gases expand to occupy the entire volume of their container. |
| C) | Different gases are completely miscible with each other. |
| D) | When the temperature is changed, the volume of gas changes much more than the volume of a solid or liquid. |
| E) | When the pressure is changed, the volume of a gas changes much more than the volume of a solid or liquid. |

What are some controls on breathing? Think critically if one of those is affected and how that would influence breathing. For example, how is breathing influenced if aortic carbon dioxide concentration goes up?
Understand the definitions of each of the ”volumes of air” in a breath. Which one is associated with deep breathing? How are these volumes altered if lung tissue is damaged or destroyed? What affect does that have on breathing? How are volumes affected with an asthma attack?
What is the affect of smoking on the lungs? Be able to identify ”big picture” changes and “small picture” changes.

The distinction between artificial selection and natural selection is important to master. Consider a bacteria that does not cause human disease. Describe these processes using illustrative examples. Your examples may be fictitious, but they need to be realistic and make biological sense
1. Describe a specific example in which the bacteria changes (evolves) in a manner that Illustrates artificial selection. Your description should contain an explanation
2. Describe a specific example in which the bacteria changes (evolves) in a manner that illustrates natural selection Your description should contain an explanation.

Which of the following is a statement of Hess's law?
A) If a reaction is carried out in a series of steps, the AH for the reaction will equal the sum of the enthalpy changes for the individual steps.
B) If a reaction is carried out in a series of steps, the AH for the reaction will equal the product of the enthalpy changes for the individual steps.
C) The AH for a process in the forward direction is equal in magnitude and opposite in sign to the AH for the process in the reverse direction.
D) The AH for a process in the forward direction is equal to the AH for the process in the reverse direction.
E) The AH of a reaction depends on the physical states of the reactants and products.
