What is rickets
This term describes a solution that contains more solute than can usually dissolve at a given temperature.
What is a supersaturated solution?

This vitamin helps with blood clotting and is found in leafy greens. It is usually given to newborns within 6 hours of birth.
What is vitamin K?
This type of mixture is uniform throughout, with particles at the molecular level, like a well-mixed cup of coffee with cream.
What is a homogeneous mixture?

16%
(15.9%)
This device is commonly used in labs to measure the absorbance of light by a colored solution.
What is a spectrophotometer?
SpectroVis is also acceptable as an answer.
This type of GMO rice was developed to combat vitamin A deficiency.
What is Golden Rice?
These fats are created during industrial hydrogenation and have been banned in many countries.
What are transfats
A deficiency in this vitamin can cause scurvy.
What is vitamin C?
If industrial wastewater contained 9.6 ppm of mercury contamination, how much mercury would be in 1 liter of the wastewater?
1 liter = 1000 mL = 1000 g
What is 9.6 x 10-3
or 0.0096 g
In the fat extraction lab from food (potato chips and chocolate), which of these foods contained primarily saturated fats and which contained mostly unsaturated fats, and how did you know?
The potato chip fat was unsaturated, as it was a liquid
The chocolate was mostly saturated fats, as it was a solid.
What is the color of the food dye that produced this absorbance graph?
What is red.
These "caviar" pearls are made by dripping liquid into a calcium bath during this technique.
What is basic spherification?
This is the chemical structure that makes phospholipids (like lecithin) emulsifiers.
What is an amphiphilic structure (hydrophilic head + hydrophobic tail)?
This vitamin deficiency can lead to neural tube defects in developing fetuses.
What is folic acid, folacin, or folate (vitamin B9)?
How much 10% solution is needed to make up 500 mL of a 2% solution?
What is 100 mL
C1V1=C2V2
(10%)(V)=(2%)(500mL)
V = 100 mL

What is the AquaAdvantage salmon.
This four-ring steroid is a lipid produced by the body and found in animal products.
What is cholesterol?
Excessive amounts of this fat-soluble vitamin can lead to liver damage and bone issues.
What is vitamin A?

It would make a 7.25% concentration, BUT the answer is 2750 mL.
This sensory evaluation method, which experts use to detect defects in olive oil, is called organoleptic testing (or sensory analysis). In 1912, a pharmacist used this type of testing to rate what other food?
Wilbur Scoville used organoleptic testing for the pungency and heat in peppers.
