You want to design an experiment to show whether drinking a large amount of Diet Coke can cause students to do poorly on a math exam. Design your experiment, then identify and explain each of the following in your experiment.
• Sampling
• Independent and dependent variables
• Control and experimental groups
• How you would evaluate your results
Answers
Obrain a list the students in your class in order from highest test average to lowest. From the list of students, using a stratified random sample, select every second student on the list and randomly assign half of them to drink 32oz. of Diet Coke before the math exam. The other half will drink nothing but water before the exam. Have each student take the exam and compare the scores between the students who drank Diet Coke and the students who drank water.
Sampling method: Stratified random sample
Independent variable: Consumption of Diet Coke
Dependent variable: Score on the math exam
Control: Group drinking nothing but water
Experimental: Group drinking 32 oz of Diet Coke
You would evaluate the results by comparing the mean score of the water drinkers' test to that of the Diet Coke drinkers. If the Diet Coke drinkers perform poorly, then we can generalize the results to the class.

how is democracy used in government today
Answers
Americans are generally positive about the way democracy is working in the United States. Yet a majority also says that the “fundamental design and structure” of U.S. government is in need of “significant changes” to make it work today.
Republicans are more likely than Democrats to say U.S. democracy is working at least somewhat well, and less likely to say government is in need of sweeping changes.
And far more Republicans than Democrats say the U.S. political system is “best in the world” or “above average” when compared with political systems of other developed nations

Read the sentence from the article: "it's drought-proof, that's one of the most important" things, said water-use expert bob yamada. according to the article, why is it "drought-proof?"
Answers
The ability of the local natural and human production resource base to supply a desirable amount of food, drinking water, livelihood resources during a drought is what is meant by "drought proofing" a place.
The main factor behind agricultural loss on a global scale is drought, which inserted a serious risk to the availability of food. When it comes to creating crops that can produce large yields in water-limited settings, plant biotechnology is now one of the most promising topics.
The primary drought stress response pathways have been identified through research on complete Arabidopsis thaliana plants, and numerous drought resistance genes have already been inserted into crops. Since most plants that have improved drought resistance have so far had lower crop yields, new strategies to decouple drought resistance from plant growth are still needed.

How are nation states, multinational states, multistate nations, and stateless nations similar to each other?
Answers
Answer:
A state may also be a society, and a multiethnic society has people belonging to more than one ethnic group, in contrast to societies that are ethnically homogeneous. By some definitions of "society" and "homogeneous", virtually all contemporary national societies are multiethnic. The scholar David Welsh argued in 1993 that fewer than 20 of the 180 sovereign states then in existence were ethnically and nationally homogeneous, if a homogeneous state was defined as one in which minorities made up less than 5 percent of the population.[5] Sujit Choudhry therefore argues that "[t]he age of the agriculturally homogeneous state, if ever there was one, is over".
Explanation:
A nation is a group of people who see themselves as a cohesive and coherent unit based on shared cultural or historical criteria. Nations are socially constructed units, not given by nature. A Nation-State is the idea of a homogenous nation governed by its own sovereign state—where each state contains one nation.Hope this helps you !!why are pillow lava rocks visible the middle of the island of cyprus
