Introduction: The circadian rhythm is the physiological process that involves in the regulation of sleep-wake cycle for every 24 hours. The proteins that are involved in this process are period protein, timeless protein, and clock protein. The period protein is usually higher during the night time, whereas the timeless protein is elevated during the day time. These proteins are responsible for the regulation of circadian rhythm.

Why is Drosophila melanogaster a relevant model of substance abuse disorders? Select all that apply. Partial point deduction for incorrect choices.     The fruit fly lacks dopaminergic neurons, making it a good negative model for addiction.     Because flies do not display dose-dependent responses to psychoactive drugs, fewer experimental treatments are needed.     The fruit fly has a homologous circadian clock, which can be manipulated to investigate changes in physiological responses to drugs.     Fruit flies are deuterostomes.     Several fly genes responsible for level of ethanol sensitivity have human orthologs.     The fruit fly also has neuropeptides secreted by brain cells that influence preference behaviors.
You are starting a dairy farm and have read that dairy cows make more milk when they are relaxed. Since your mother listens to classical music to relax, you wonder whether cows listening to classical music would make more milk. You have 40 cows.  You decide to test the hypothesis that playing classical music will make cows produce more milk.  Briefly summarize how you will design a controlled experiment to test your hypothesis.  Then Identify the explanatory variable, the response variable, and the controlled variable in your study.  And, finally, make a prediction and explain how you would interpret your results.
