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:
An important characteristic of urine is its specific gravity or density, which is ________.
A. the same as water
B. less than water
C. much higher than water
D. slightly higher than water

Intermolecular hydrogen bonds
A controlled experiment is when the experimenter can change one variable in the experiment and completely change the results.
Redi experiment involved a closed jar with rotting meat on the inside. He waited for a few days and found no new forms of life in the jar.
He then did the same experiment, but this time he took the lid off the jar. After those few days he found there were maggots in the rotting meat from flies.
This is a great example of a controlled experiment, because he only had to change one variable to completely change the results. In this case that variable was just removing the lid from the jar.
Redi was trying to prove spontaneous generation with his experiment. Although, it failed.
Spontaneous generation: When life forms from non-livings.
Redi disproved spontaneous generation, but proved biogenesis.
Biogenesis: When life comes from other living beings.
He proved biogenesis because the flies had reproduced when the jar was opened.
