some urinalysis lab questions?

[Ineedhelponbio]

1. Does the chemical content of urine change throughout the day? Explain.

2. While a blood sample contains glucose, albumin, and chloride molecules, a normal urine sample contains only chloride molecules. What does this indicate about one of the functions of the kidneys?



Also,
develop a hypothesis about whether or not urinalysis is a useful tool for helping to diagnose the medical condition of people.

#2 is pretty obvious isn't it? What could have happened to the other blood components?
