The water in your body and the water you drink
Yes, your urine comes out darker if you are not drinking enough water.
When you run a marathon you get very hot and the body has to use the water in your system to cool itself down which makes the urine more concentrated because there isn’t as much water in it. It also makes a smaller quantity of urine come out of the body because the water that would usually come out as part of the urine would have already come out as sweat from the body trying to cool itself down.
It's not necessarily bad to drink lots of water before a urine test but it could make you have to reschedule your appointment. The more water you drink the more diluted your urine is going to be. If your urine is to diluted they will make you come back after a day or two.
Sometimes sperm may come out with urine
Personally, i dont think that drinking alot of water will make your urine test come clean. But, drinking alot of water can help get things out of your system faster. This can help because doing things (such as drinking, etc.) dehydrates you and by drinking water you will re-hydrate your body and make your system cleaner, faster.
Urine is usually around a pH of 7, or neutral (like pure water). The problem might come with the extreme amount of salts and ammonia present in the urine, which may be harmful to the plant. The best solution is probably to rinse it with a lot of water. If it is in a pot with good drainage, take it outside or over a sink and water it repeatedly for a while, letting the water just flow out of the bottom to flush out the urine. If the pot has no drainage, it might not be a bad idea to replant it into a pot with good drainage, using soil that wasn't saturated with urine, and you might want to water it a few times, again to flush any of the urine that might have come in the soil around the roots.
IF ANYONE ACCIDENTLY swallows human urine, they will not be "poisoned". When a healthy person urinates, it actually come out sterile. But seeing how urine is the "waste water" of the human body, I would not recommend that people drink urine, whether it is their own or someone elses.

Urine doesn't come from the vagina.
Human beings 'pee' urine, not water. Urine can sometimes appear clear if one is very well hydrated, but it is still urine.
