The biggest evidence of natural selection is the progression in the morphology of fossil over time. Some of the fossils are of extinct species. This evidence point to the fact that species evolved from other species, gradually evolving new physical features. This is related to the environment in which they lived in since their morphologies allowed them to be well adapted for their environments.
I only know the answer for No 2)

Minerals are also needed for the body although this should be taken in a very controlled amounts only.
Minerals and vitamins combined form the micro-nutrients of the body.
With micronutrients, only relatively little amount of nutrients is required to improve health. They are usually in milligram and microgram amounts and are enough to sustain to the metabolism and growth supplication. On the other hand, macronutrients are those that need large portions and quantities such as carbohydrates, fats and proteins. We need more of these to be converted to energy for movement and muscle growth. </span>
