Answer:
1]
Most grow in tap water, but a denatured water may be best for sensitive plants. Cuttings that root in water must have the liquid changed frequently and aerated once in a while. A simply drinking glass, vase or other container that is large enough to hold the cuttings are sufficient
3]Uranus and Neptune are nearly the same size, Uranus is less dense and has less mass, so your weight would be less. Distance also has an effect on the pull of gravity.
4]All seeds need water, oxygen and the right temperature to germinate. Dormancy is a state of suspended animation in which seeds delay germination until conditions are right for survival and growth
