Lab technician

Chemical used is the main independent variable. Cell growth was the dependent variable or response variable. The cell type and dose are both being tested within the experiment leaving lab technician.
I personally have to go with nonhumans.
Most of the animals are defenseless, especially when humans fight unfair.
Think about, humans kill lions. But it should be a fair fight, obviously the lion would win. But humans have crafted weapons to harm these creatures a lot of the times for absolute no reason besides greed.
I feel like animals are very defenseless and clueless and humans take advantage to that to the max- sadly.
If you need a longer explanation, I can give more.
Hope this helps!

I think its the first one
Answer: C) Is accepted as true until proven false
==========================================================
Explanation:
We cannot prove the hypothesis to be 100% true because there might be data out there that we haven't accounted for, or some scenario that we haven't thought of yet. There's always going to be room for uncertainty and doubt. Keep in mind that such doubt does not necessarily mean that the theory is automatically false.
So all of this rules out choice A.
Choice B is ruled out as well because data supporting a hypothesis doesn't falsify the hypothesis. The term "falsify" means "to prove false" as you'd expect.
Choice C is the answer because the data seems to support the hypothesis and again we leave room for error. It's quite possible that in some unspecified date in the future, there are better methods of measurement to get a better sense of what's going on.
Choice D is ruled out because a law refers to something like the law of gravity. It's something you observe but it doesn't explain why something works. It doesn't provide the underlying mechanics of what's going on. We simply just report what we see which is exactly what an observation is.
The answer is 1,350 because you have to subtract.
