Answer: Adaptation
Explanation:
The adaptation can be defined as the biological mechanism that makes the organisms suitable to survive in the changing environment. The adaptation can be done at the genetic, molecular, physiological and structural level all these adaptations increases the likelihood of survival of the organisms and increases their rate of reproduction. The beneficial traits acquired due to adaptation are passed from parents to their offspring. Thus the adaptation becomes profound and observable in living beings.
There is no solid scientific evidence that humans have been cloned.
The answer is E, graduated cylinder.
Meanwhile beaker and test tubes may have markings, but they're not as accurate. Especially in beakers, their wide diameter only makes an approximate volume, as it is very likely to have a reading mistake on that. Their main function is not to measure volumes, thus there marking may already have an mistake.
And in watch glass and evaporating dish, they're both very shallow and wide in diameter too, so they're not for measuring volumes. Plus, not all of them have markings.
And in graduated cylinder, the thin shape makes the reading a lot more accurate and the main purpose for that is to measure volumes. They also come in transparent tubes that can make the reading clear and easy to read.
You could talk about pollution, trash on beaches...etc
