Answer:
The nervous system uses cell-communication by electrochemical signals that hormones, neurotransmitters or cytokines
Explanation:
Cell communication is vital to maintain internal environment thanks to homeostasis process which regulates the responses to internal and external stimulus. The functioning of cells depends on the electrochemical signals, these allows the communication and coordination among a group of cells of the tissue.
There are different type of loop-responses:
Negative Feedback Loops;
Reaction that causes a decrease in function, in response to some stimulus. The maintenance blood pressure, blood pH, oxygen/carbon dioxide balance, water balance (osmoregulation),calcium levels, among others are examples of negative feedback loops.
Positive Feedback Loops
Are involved in the amplification of the stimulus. D
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:
did you try searching the paper up?
Explanation:
According to science, yes – happiness, indeed, has a heritable component. It’s a finding that is surprising and not surprising at the same time. It's surprising because of our culturally-sanctioned convictions that with our choices, thoughts, and behavior, we have the final say on how well we function in our lives, not our circumstances. But it's also not surprising because if our genes play a part in shaping who we are in the world, they will also have a say in how we pursue and find happiness. People might inherit genes that put them in advantageous or less favorable positions. Depression is genetic...
