These are the three explanations that give reasons that scientists are considering renewable source of energy:
1. Renewable sources are assets implies they are old and reliable sources.
2. Most renewable sources are effectively accessible in nature.
3. Renewable resources are cost-effective in contrast with non-renewable resources.
A renewable energy source implies energy that is feasible, that can't run out, or is unending, similar to the sun. It is additionally named 'alternative energy'. These assets are fit for recovery. The recovery of these sources includes a few biological cycles on a time scale. Sun, water, air, and heat from the earth are sustainable sources that we can use to make solar-based, tidal, wind, and geothermal energy. Renewable energy is additionally called green or eco energy.

Melanin provides pigmentation to the skin and it also provides UV ray protection (which is its role in the epidermis).
Answer/Explanation:
Natural selection - over time - selects for traits that improve fitness. A butterfly with wing coloration that looks like a hungry owl would certainly be a deterrent to their natural predators, such as smaller birds. This is because the owl is the predator of the smaller birds, and their instinct is to avoid the owl.
If a mutation arose that resulting in coloration that looked like an owl, (or at least slightly menacing) this would be beneficial to the butterfly, as it would be more camouflaged from predators. This means it would be more likely to reach reproductive age and pass the mutation onto its offspring, who would also have a competitive advantage.
Over time, this would lead to a population of butterflies with coloration that looks more and more owl-like .
