In the vacuum of space there is no molecules. Sound waves get to your ears by bouncing off of molecules in the air. No molecules in space's vacuum means sound waves have nothing to bounce of off so they can not reach our ears meaning we hear no sound.
Urine's specific gravity, which is somewhat greater than that of water, is a crucial physical property.
Characteristics of urine:
- Osmolarity is typically harder to quantify than specific gravity, which measures the amount of solutes per volume of a solution. Because there are solutes in urine, its specific gravity is always higher than that of pure water (water = 1.0). Since specific gravity is a less precise predictor of urinary solutes, laboratories may now directly detect the osmolarity of urine.
- Osmolarity, or mOsmol/L, is the measure of how many osmoles or milliosmoles are present in a litre of a fluid. The osmolarity of urine can range from 50 to 100 to 1200 mOsmol/L of water.
Therefore, it is concluded that the correct solution is an option (D), i.e., slightly higher than water.
The complete question is:

A. the same as water
B. less than water
C. much higher than water
D. slightly higher than water
