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 .
The given statement is true.
Some of the health science sites may restrict employees from wearing perfumes or other fragrances because the chemicals in the fragrances can stimulate reactions ranging from headaches to palpitations of heart in some of the individuals who are sensitive to them, making it tough for them to work efficiently.
With time, the individuals getting exposed to the chemicals present in the fragrances become more sensitized to them to the point that they can no longer tolerate any more exposure. This can initiate breathing issues, nausea, sneezing, disorientation, and in extreme situations, they can even go into shock.
