Label these solutions 3% NaCl, DI H20, 5% glucose, 12% glucose, 1% glucose as hypertonic, hypotonic, or isotonic. Also state what would happen to the red blood cell (crenation,stays nice,hemolysis)

For this homework assignment, the task is to come up with a way to test the hypothesis that internet use impairs classroom performance experimentally.

1 What experimental design will you use to test the hypothesis? (2 points)

2 Why did you decide to use this particular design? What specific threats to validity guided your choice of experimental design? (4 points)

3 How will you operationalize your independent variable? Here you first have to define the construct (so that we can evaluate whether your operationalization appropriately captures the construct). Then you also have to describe the general outline of the experiment so that we can evaluate your manipulation in the right context. For example, where will you conduct the experiment? Will you have a cover story for participants about the purpose of the study? If so, what will you tell them? Finally, how will you ensure that your manipulation of the independent variable is “clean” (no confounds)? (6 points)

4. How will you operationalize your dependent variable? Again, you must first define the construct, and then explain how you will measure it. You must also explain why you decided to measure your dependent variable in this way – and not in another way. (6 points)

5 State your hypothesis – using your specific operationalizations of the constructs. (2 points)

6 How will you test your hypothesis statistically? Under what circumstances would you conclude that the data supports your hypothesis? (2 points)

In Chapter 16, 17 and 18 we focus more on the structure and function of organisms, as well as the emphasize the immune and reproductive systems. Respond to the following two prompts relating to these three chapters: In section 16.3 we learn about the vertebrate circulatory and respiratory systems, both of which are quite different from the respiratory and circulatory methods found in invertebrates. Use the information from this section to compare to information from a previous chapter, or other online resources to answer the following two questions: How does a closed circulatory system function differently from an open circulatory system? And can you identify any benefits to an open circulatory system? Identify two differences (either structures or functions) between gills and lungs in terms of how oxygen is captured from the environment. In section 18.3 we learn more about human reproduction, including the concept of gametogenesis or the production of egg and sperm cells in humans. Create a table or write a brief summary (whatever makes sense to you) that compares spermatogenesis and oogenesis. Include a bit of information about the hormonal control of reproduction in your comparison.

What are the methods of micropropagation of plants? List and explain in detail what they consist of.

, Explain in detail the anatomy behind “first pass metabolism” and then explain in detail the physiological significance.

For each hypothesis test, state the claim in mathematical notation, state H₀ and H₁, calculate the test statistic and p-value (unless given), state your decision about H₀ (reject or fail to reject), and state your conclusion in terms of the original claim.

1. At a 0.05 level of significance, test Bill Bradley’s claim that the majority of voters would vote for him. Assume that sample data consists of 1068 randomly selected voters, 540 of whom indicated that they would vote for Bradley.

2. The Sylvan Pharmaceutical Company makes tubes of antibacterial cream that are labeled as containing 4 ounces. In testing a claim that the mean content amount is less than 4 ounces, a p-value of 0.220 is obtained. What do you conclude? Explain.

1. A single firm’s innovations in production technology often benefit the production of other firms because these other firms learn about the new technology and can use some of the ideas in their own production.

1. Is there an externality here?
2. How would an economist rank the following two policies in this situation? Why?
   1. A tariff on imports, to make sure that domestic production using the new technology occurs.
   2. A subsidy to domestic production, to make sure that domestic production using the new technology occurs.
3. What third policy (a tax or a subsidy to something) would the economist recommend as even better than these two?

Please Explain them in detail and No bad handwriting please! Thanks! :)

3. In this section we have said that the Richter scale and other logarithmic scales are compressed. Explain in a way that a fellow student could understand what is meant by a compressed scale, and use a couple of examples to show how the compression works in practice.

On page 12-7 (Section 12-3b), the text notes that employers may earn a “work opportunity credit” for hiring members of target groups, such as veterans. If an Illinois employer is considering hiring a qualifying veteran, are there any procedures it must follow or any special documentation must it obtain and keep in order to demonstrate that the new employee is a qualifying veteran? Are there any special forms that must be used? If so, please describe the procedures, documentation or forms in detail.

Please answer each question in complete sentences, and cite name and number of the IRS publication or form/instruction where you found each answer, and the page number on which the answer is found. Use your own words in the answer – do not copy the IRS’ language.
