Correct answer is C. It's really simple.

A pharmaceutical company wanted to test a new drug developed to lessen the effects of the common cold. To test this drug, scientists tested 50 volunteers, each of whom was suffering the effects of a cold. Twenty five of the people were given the drug, while the other 25 were given a placebo, a sugar pill. None of the participants knew who was taking which pill. All participants received a pill at 8:00 am daily for the first three days of the study. All participants lived in the same environment, with the same climate, eating the same diet, and having the same level of activity. The severity of the cold, hence the effectiveness of the pill, was determined by the number of tissues each person used within 24 hours. At the end of a seven day period, it was concluded that those with the sugar pill had their symptoms disappear as well as those who had taken the new wonder drug. The executive committee decided to produce the drug anyway thinking that the public would do anything to relieve the symptoms of a cold. Type of Variable Description Dependent Variable that the researchers actually measurers, counts or observes. It is what the researcher thinks will change in response to the experimental treatment. Independent Variable that is intentionally changed by the researcher. Standardized or Controlled These variables are held constant between each group to help prevent these factors from influencing the dependent variable.

2) What is the hypothesis?
3) Identify the independent variable versus the dependent variable.
4) What variables were held constant in this study?
5) What was the control group?
6) What data was collected during the study?
7) What this data qualitative or quantitative?
8) What was the study's conclusion?

Answers

Answer:

1. Research question is a question which is the aim of any experiment or research, in this case, the question addressed by the study is - Testing the effects of a newly developed drug to lessen the effects of the common cold.

2. Hypothesis is an explanation for the reason for any problem it does not need the evidence and completely based on logic.

The newly developed drug is able to lessen the symptoms of a common cold.

3. Independent variable is a variable manipulated or changed during the experiment:

Administration of drug or placebo (sugar pill)

4. Dependent variable is the response to the effect of the independent variable:

Number of tissues for each volunteer

5. Control group is available that remain constant throughout the study or used to compare the results:

Administration of sugar pill to 25 volunteers

6. Data is the result that the study generated -

At the end of the 7 days or one week period, symptoms of common cold disappear in both sets of volunteers who had taken either the drug or the placebo.

7. Data in this study is found is Qualitativedata as the drug is not administrated in doses.

8. Conclusion of the study is that the Placebo effect present as sugar pills relieve the common cold so This drug needs even more analysis.

Case-study.A 25 years old male with past medical history of alcohol abuse was admitted to the ED with complains of severe lower back and bilateral legs pain. He had been running twelve miles every day for two weeks using 3 lbs weights attached to each leg and 2 lbs weights attached to each arm preparing for the marathon. The other complaint was a dark color urine for two days.
What is the cause of his symptoms. Explain the mechanism.

Answers

Answer:

The lower back pain and bilateral leg pain is due to over and intense physical activity which causes stretching of ligaments and muscles resulting in back and leg pain. Such pain can be managed by limited or by reducing physical activity. The dark color of urine is due to the presence of bile (bilirubin) in the urine. Here the patient has a past medical history of alcohol abuse. Excessive alcohol intake enhances gut permeability resulting in enhanced absorption of bacterial endotoxins. Excessive endotoxins in the liver cause damage of the kupffer cells in the liver, resulting in the release of bilirubin in the blood which ultimately passes through kidneys into the urine.

Zach Corp. pays commissions to its sales staff at the rate of 3% of net sales. Sales staff are not paid salaries but are given monthly advances of $15,000. Advances are charged to commission expense, and reconciliations against commissions are prepared quarterly. Net sales for the year ended March 31 were $15,000,000. The unadjusted balance in the commissions expense account on March 31 was $400,000. March advances were paid on April 3. In its income statement for the year ended March 31, what amount should Zach report as commission expense?

Answers

Based on the information given the amount that Zach should report as commission expense is $450,000.

Using this formula

Commission expense=Percentage of net sales× Net sales

Where:

Percentage of net sales=3%

Net sales=$15,000,000

Let plug in the formula

Commission expense=3%×$15,000,000

Commission expense=$450,000

Inconclusion the amount that Zach should report as commission expense is $450,000.

Rosiglitazone is an antidiabetic drug meant to target adipose cells, enhancing insulin effects. The drug mimics the fatty acid metabolites that bind to a nuclear receptor found mostly in fat, liver, and a few other tissues. Cortisone is a type of glucocorticoid mimic that binds to a nuclear receptor, activating the receptor's transcriptional regulatory function. The ligand-activated receptor binds coregulatory proteins, and the protein complex targets gene transcription involved with inflammation. Which of the following statements about these two drugs best describe their mechanism of action? Choose one or more: A. Rosiglitazone will bind to its receptor (peroxisome proliferator-activated receptor), and the receptor- B. Zinc fingers bind at the top of rosiglitazone receptor dimers as a stabilizer, allowing the alpha helical C. Receptor dimers with bound cortisone bind to the DNA target using a zinc finger to bind to an inverted D.
