Answer:
D Serotonin levels, because this is the variable she is measuring .
Explanation:
Dr. Whitlock is looking for the effectiveness of the medication.
A. is incorrect because it say the type of medicationn was being manipulated if this were true this would be the independent variable (the thing the scientist or person changes)
So just by knowing why A is wrong we can automatically rule out
A.
C. and
E.
That leaves B. and D. giving you 50/50 chance of being correct if this were on an actual test/EOC.
I am a little unsure of if it would be B or D at first so I decided to leave some information for you in case you disagree or want to check I'll leave it up to you to officially decide if it's B or D but I personally believe it's D. here's the information:
You can Eliminate B. because Dr. Whitlock is looking for the effectiveness of the medication and D. is talking about the serotonin levels, serotonin affects your mood, low serotonin levels can cause depression. But if serotonin effects your mood is that something a anti-psychotic medicine be prone to fixing or would it be the hallucinations? which many experience but do the serotonin levels effect your sanity more than the auditory hallucinations, cause people can have inaudible hallucinations.
I may be looking into to this WAY too much and OVER thinking it but I hope this at least helped you a bit giving you a 50/50 chance of getting this right. Sorry if this is confusing.
( I found the same question but with the letter options thats how I know the options and how I ruled out some)

Answer:
Bart can travel 130 miles in 2.5 hours with this rate
Explanation:
Bart travels 52 miles per hour
For 2.5 hours first find for two hours and then for half hour. finally add this two and half hour to get for 2.5 hours.
2.5 hours=2 hours + half hour
2 hours= 1 hour × 2
= 52 miles × 2 = 104 miles
half hour= 1 hour ÷ 2
=52 miles ÷ 2 = 26 miles
2.5 hours = 104 miles + 26 miles
= 130 miles
From the research that I have done, exports to the United States increases the country's balance of trade. Possibly creating a surplus of goods.
The correct answer would be an increase in exports to the United States
Here is a good example of what you are trying to understand.
<span>If a country exports a greater value than it imports, it has a </span>trade surplus<span>, </span>positive balance<span>, or a "favorable balance", and conversely, if a country imports a greater value than it exports, it has a </span>trade deficit<span>, </span>negative balance<span>, "unfavorable balance", or, informally, a "trade gap". A positive balance adds to </span>gross domestic product<span>, while a negative balance subtracts from GDP.</span>
