Answer:- 0.0002 ppm
Solution:- 1 ppm is one mg of solute per liter of solvent or one kg of solvent.
It asks to convert 
pb in blood to ppm. density of blood is 
.
Let's convert micrograms to milligrams and also calculate the mass of blood from it's given density. The set up could be made using dimensional analysis and doing unit conversions as:
First the set up for the conversion of micrograms of Pb to milligrams:
= 
Now, the set up for converting dL of blood to kg using it's given density and unit conversion from dL to mL as:
= 0.200 ppm

The answer is C!!!!!!!!!!!!!!!!!!!
it is over 32 degrees Fahrenheit (freezing), and below 120 degrees Fahrenheit (boiling)
photosynthesis makes the glucose that is used in cellular respiration to make ATP. The glucose is then turned back into carbon dioxide, which is used in photosynthesis. While water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.
