If I'm not mistaken I believe it is called genetic modification.

Answer:

When scientists take the genes of two different species and combine them, we call this genetic engineering.

Explanation:

Genetic engineering is a collective term for the molecular techniques used to alter an organism's inheritance. The techniques range from inactivating a gene or introducing a small change in a gene (a single inheritance system) to transferring genes from one organism to another. A genetically modified organism is often referred to as a transgenic organism.

Genetic engineering is used for example in biotechnology and medicine. For example, insulin or human growth hormone is produced in bacteria and insect and / or herbicide resistant cereals are grown for commercial use.

Of course, in addition to genetic engineering being a technically difficult area, it also involves ethical aspects, especially in terms of human application and animal cloning.

Dr. Whitlock is conducting an experimental study on the effectiveness of antipsychotic medication Which of the following will mo

NemiM [27]

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

C. and

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)

Why were societies in the Paleolithic period more egalitarian

allsm [11]

Because there was no one to set rule to the peoples, and because of this, everyone possessed the same amount of skill, and women and men were treated equally

Slaveholders claimed they treated slaves better than factory owners treated their workers. Is this a valid comparison? Explain.

Ivanshal [37]

Answer:

I dont think it is

Explanation:

Coming from a black person the way that slave owners treated black people was inhumane. We wre literally publically mocked and beaten. No one honestly had to go through that but black people. And till this day it still hurts and puts a nasty taste in my mouth about slave holders or owners

Helppp quick pointsss

Margaret [11]

Answer:

1) The angle would be 150 degrees

a) coordinates would be ( $-\frac{\sqrt{3}}{2}$ , $\frac{1}{2}$ )

b) Trigonometric ratios:

sin: $\frac{1}{2}$

cos: $-\frac{\sqrt{3}}{2}$

tan: $-\frac{\sqrt{3}}{3}$

csc: 2,

sec: $-\frac{2\sqrt{3}}{3}$

cot: $\sqrt{3}$

Explanation:

$\frac{17\pi }{6}$ simplifys to $\frac{5\pi }{6}$ which has a reference angle of $\frac{\pi }{6}$ . We can take the coordinates of $\frac{\pi }{6}$ and make the x value negative to find the correct coordiantes. Then, using those coordinates, plug the into the trigonomic equations.
