The statement is - True.
The production of the nuclear energy by the nuclear reactors requires lot of water. The water's role is to constantly keep cool the reactors because if they overheat there can be a disaster of big proportions.
Because of the heating up of the water the water changes its properties slightly. Those changes have big environmental impact, easily seen in the local flora and fauna in close proximity to the nuclear reactors. There is way to big of a percentage of bad mutations among the flora and fauna where the water is released from the nuclear reactors, where very often there's animals with either more or less extremities, two heads, weird growth and shape of the plants etc.
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 .
I’m pretty sure it’s the permBain era
It’s C because they took out the letter A from the new strand of DNA. btw deletion means to take away and substitution means to sub in a letter. hope that helped!
Adaptation because organisms adapt to avoid extinction.
