Another difference between the two forces is the fact that gravitation only attracts, while electrical forces attract when the electrical charges are opposite and repel if the charges are similar. Thus, gravitation is considered a mono-pole force, while electrostatics is a dipole force.
Answer: 1.) The three important need for water includes:
--> it is important for biochemical mechanisms such as digestion and cellular respiration
--> it serves as a habitat for many species of plants and animals.
--> it participates in cycling of all materials used by living things.
2.) Water is distributed through the biosphere by WATER CYCLE.
Explanation:
Water is necessary for the maintenance of life which is distributed through the biosphere by a cycle known as the WATER CYCLE.
All living organisms contain a high percentage of water. Plants take up water form the soil in large amounts and lose most of it by transpiration. Only a small amount of the absorbed water is used in photosynthesis and other metabolic reactions. Animals take in water constantly from their food and drink. Like in plants, most of the water they take in comes directly from the non- living environment and not through the food chain. They lose most of this water in the air they breathe out, in faeces and urine. All living organisms release water during cellular respiration.
In nature, water circulates mainly within the abiotic ( non living) environment; only a small portion recycles through living organisms.
Water cycle is maintained mainly by the evaporation and condensation of water in the abiotic environment. Water that enters the biotic components of the ecosystem returns to the abiotic environment through respiration, decay, excretion and transpiration.

Natural selection involve natural causes while artificial selection is by human breeding or human intervention.
The process of domestication is called artificial selection. Like natural selection, artificial selection acts by allowing differential reproductive success to individuals with different genetically determined traits in order to increase the frequency of desirable traits in the population. Natural selection and selective breeding can both cause changes in animals and plants. The difference between the two is that natural selection happens naturally, but selective breeding only occurs when humans intervene.
