Answer:
Water cycle
Explanation:
The water cycle, also called as the hydrologic cycle that describes the continual flow of water i.e on over and beyond the surface of the Earth.
The nutrient cycle refers to the cycle in which there is a movement and exchange of organic and inorganic matter
Therefore the water cycle is not a nutrient cycle and hence the same is to be considered
In organic chemistry, there are already known reaction for synthesis that have been studied and experimented by scientists. For reactions involving a Nickel catalyst in the presence of hydrogen gas, the reaction would be hydrogenation of alkene to yield an alcohol. These reaction is anti-Markovnikov, or proceeds by violating the rule of Markovnikov. His rule states that 'the rich gets richer'. This means that the heavily substituted C atom of the alkene chain would receive another substituent. Therefore, the complete reaction would be
4-ethyl-3-hexene -------> 4-ethyl-3-hexanol
In structural formula, the reaction goes as follows as shown in the picture.
First of all scientific evidence is anything that is gathered using the scientific method that supports a hypothesis can be considered. According to me, a good place to start evaluating is to look at whether the evidence was collected using good scientific principles.
Good luck :)
