If you are working as a forensic scientist and are given an unknown powder from a crime scene, what would you hope to find out about the powder?

If I am working as a forensic scientist and I am given  an unknown powder, I would analyze this and hope to find out where did this belong.

You find that the unknown powder contains the illegal drug cocaine. If someone where to ask you to determine the purity of the substance, what would they mean? Why is purity important in crime investigations?

The purity of the substance would mean that how much of the main component of cocaine is present in this powder. Purity is important in crime investigations because it will help you determine how much of the main component is present in that substance, the main component is the active ingredient of that substance.
Of the controlled substances, which schedule of drugs is the average person most likely to have in their homes? How are the controlled substances in this group different from those in the other schedule levels?

The schedule of drugs that is mostly present at home is antibiotics.

Answer:

1. 39 J; 2. 3.9 % usable; 3. 96.1 % unusable

Step-by-step explanation:

1. Available energy

Energy consumed              = 1000 J

Less waste         = - 177 J

Less respiration = <u>-784 J </u>

Total energy lost                = <u>-961 J </u>

Available energy                =   39 J

2. Percent of total energy usable

The chipmunk could use only 39 J of the original 1000 J.

% of energy usable = 39 J/1000 J × 100 % = 3.9 %

3. Percent of energy unusable

The chipmunk lost 961 J of the original 1000 J.

% of energy unusable = 961 J/1000 J × 100 % = 96.1 %
