TRUE. Most drugs are eliminated by the kidneys in urine although some are excreted in saliva, sweat, or exhalation.
I am not sure but I think the answer would be A. Since where they live caused them to need to adapt.
1) The first reactant is incomplete.
2) The reaction is a combustion reaction and it is easy to infere that it is the combustion of the alkane with 3 carbons.
3) The general chemical formula of the alkanes is

4) Hence the equation is:

5) The name of the alkane is propane, so the word equation is:
propane + oxygen → carbon dioxide + water
6) The equation is unbalanced. This is the balanced equation:

7) It is, as the combustion of any hydrocarbon, a redox (reduction-oxidation) reaction, where the carbon is oxidized and the oxygen is reduced.
8) This kind of reactions release a lot of energy.
The correct answer is The shape of a PROTEIN molecule resembles a messy group of coat hangers.
To function, proteins must have the necessary amino acids in a specific sequence and be folded into a specific shape. A sequence is a continuous series. Proteins loop, coil, and crinkle into complicated shapes. The shapes appear more like messy groups of wire coat hangers than stacks of neatly folded dish towels.
Answer:
Groups of smaller cells can have the same volume as one large cell, but be much more efficient. This is because of a higher SA/V ratio. Small cells have space between to better get nutrients.
