What is the purpose of doing the biuret test with water?
the test is to determine if the substance you are testing has protein in it
Why should the concentration of sample be low in spectrophotometer readings?
When doing reading on a spectrophotometer, the sample being studied is either a color change or a precipitated compound, depending on the wavelength that it is being read. If it is a precipitated compound and it has a very high concentration, then you run the risk of the light being used to measure the absorbance not going through. In which case you have total absorbance but it is inaccurate in helping you determine the concentration of your sample because you are unsure where the concentration limit is for that wavelength, and your sample could possibly be able to absorb more. In which case you still can't calculate the concentration of the sample.

People were most likely doing what they always did cause back then they wouldn't of know a volcano was about to explode.

Why were you instructed to keep swirling the flask?
To mix the reactants. Assuming you have been doing a titration experiment and I am doing your homework its so as you add the acid/alkali you can accuratly close the biuret when the indicator changes colour.
Why is it important to have a representative sample when doing surveys?
Because without representative sample, your results will not be valid.

If your 10 and you have a crush what would you do?
Firstly, I am pleased you know it is just a crush. Most people have them and it is perfectly normal. As long as it is someone about your own age then maybe a first move would be to gently flirt with them. That way you can find out how they think before doing anything further.
Should you talk to the friend of the guy that you like?
Sure by doing so you can find out more about your crush and it could give you ideas about what to talk to your crush about.

To text your crush and ask how his day is going allows him to know that you are thinking of him. That you care and like to know he is having a good day.
Why would having a larger sample size be a better idea than having a samll sample size when doing an experiment?
less bias and error occur when sample size is larger
Why is having a larger sample size be a better idea than having a small sample size when doing a experiment?
1. Better chance of uniform sample. 2. Material for confirmations if needed.
Will nuerontin dilute a urine sample?
Why do you wanna know? You shouldn't be doing drugs!
How did Harry develop a crush on Ginny?
When he was doing his sixth year in Hogwarts, one day Harry saw Ginny and Dean Thomas snogging. After seeing that he felt doing the same with Ginny. He tried to control himself, but couldn't. This is how he developed a crush for Ginny.
You're always doing these crazy things and whenever your crush is around and sees these things he keeps looking at you so does that mean something important or does he just think you're weird?
Maybe but that's because your crush doesn't know that your doing these crazing things because your crush is there. You should just Calm down and just talk about daily stuff. Like how you hate doing homework or your pet did an amazing thing. Just chat about normal things when the crush is around. Then you should take the oppertunity to chat a lot with the crush and get to know him/her. Good things will come out of it. Maybe they will become your friend....or even more
