Question

1. A researcher wants to develop a new pharmaceutical compound to treat pain. Which of the following strategies will likely be the most effective process?
A. Test extracts from newly discovered plants for pain-killing substances.
B. Read anthropological studies to discover plants identified to relieve pain.
C. Study molecular structures of existing pain medications and make structural analogs.
D. Research the pain receptors of people who have unusually high pain thresholds.

2. A student conducts an investigation in which she dissolves 1 gram (g) each of several substances in 50 milliliters (ml) of water. She has 12 identical plastic cups of water. She places 1 g of salt in three cups, 1 g of sugar in three cups, and 1 g of baking soda in three cups. Three cups contain only water. She places all the cups in a freezer and records the temperature in each cup every 15 minutes for 4 hours.

Which of the following is the best way for the student to display the results of this investigation?
A. Pie chart
B. Bar graph
C. Venn diagram
D. Line graph

Which of the following question is the student most likely investigating?

a. What effect does cooling have on the solubility of different solutes?

b. How is the cooling rate of water affected by different solutes?

c. What effect do different concentrations of solute have on the freezing point of water?

3.During a 56-week test. 3.731 patients participated in a double-blind trial. Participants did not have type 2 diabetes mellitus. One group of participants received once-daily subcutaneous injections of liraglutide at a dose of 3.0 mg. The other participants received a placebo. Both groups received counseling on lifestyle modification. At the end of the 56 weeks, the body weight of each participant was determined. Which of the following best indicates the question that was being investigated in the study?

A. Can body mass index affect the onset of diabetes?

B. is liraglutide effective for weight loss?

C. What effect does liraglutide have on diabetes?

D. How does lifestyle modification counseling affect body weight?

Answer 1

Ans 1 option c is a correct answer.

Explanation - this method is cost effective because a research just need to study existing pain medication and release a hypothesis and bring changes in the constituent of the pain medication. This is less time consuming also. In option a reasercher has to start from the beginning and require testing at big level.

Option B is not possible because this option doesnt provide exact and explained result.

Option d is not possible because this is not effect for development of the drug medication and least effective methods.

Hence option c is a correct answer

Ans2. Option d is a correct answer

Explanation it help in assessing the change in one quantity over a period of time , here in the conditions solutes freezer and assess after every 15 minutes for 4 hours . Other methods doesn't support the 2 quantity and 2 axis like X and y axis with comparison.

Second part answer

Option c what is the effect do different concentrations of solute have on freezing point of water.as per the condition the student. Need to note the temperature every 15 minutes which suggest the freezing point assessment fo different concentrations.

Ans3 option a is a correct answer.

Explanation - body mass index is w(in kg) /( height in meter). The body mass index tell the health range. The obesity and malnutrition is measured with the help of the BMI and obesity is the risk factor for many diseases such as diabetes, hypertension , cardiovascular diseases. Physical inactivity leads to obesity which directly affect the client health. The investigation study suggests the relationship of obesity and oneset of diabetes.

Hence option a is a correct answer .
