Why must the standards and samples stand for 10 minutes before the absorbances are read?
This is to allow time for the particles in the solutions to become evenly distributed and stable.

It would be 40 minutes before 12.
What is 12 minutes before 6?

Calibrated the spectrophotometer with?
a blank solution before starting the experiment to account for any background interference. This ensures accurate and reliable measurement of the absorbance values of the samples. It helps to establish a consistent baseline for the instrument to improve the precision of the results obtained.
Can a turbid sample be measured for absorbance in UV spectrophotometer?
Yes, turbidity can interfere with absorbance readings in a UV spectrophotometer by causing scattering of light. To accurately measure absorbance in a turbid sample, the turbidity would need to be reduced or removed before analysis, for example by centrifugation or filtration.
How do you get free food samples?
You can contact the manufacturer and ask if they have samples. I've done this before. There are also several web sites that catalog various free samples, for which you can apply.
How many minutes is it before noon if 70 minutes?

What substance was used to treat the DNA before placing the samples into the wells?
To treat the DNA before placing the samples into the wells, a loading dye containing substances like glycerol and bromophenol blue is commonly used. The loading dye helps to visualize and track the DNA samples as they move through the gel during electrophoresis.
