Biologically water is essential for life and for enzyme activity and metabolism and, is a solvent for biological nutrients and other chemicals. Physically, soil moisture affects soil temperature (water is good conductor of heat) and soil aeration.oil moisture. Soil moisture affects the soil biota in two ways.

Your blood is actually always red! Blood in your veins has very little oxygen and is a dark red color that looks almost blue when covered by your skin. Your arteries have bright red blood because it has a lot of oxygen in it that is being carried throughout your body to be used by tissues.
Arteries are red, because they are carrying oxygenated blood to the various parts of your body. Now, if you were holding your breath, and floating in space with no space suit, and THEN cut yourself, it could possibly turn blue quickly after exiting your body, but it would still come out red to begin with.ince it has something to do with oxygen entering the blood so it turns red, but if your in outter space wouldn't it stay blue.
