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.
A scientific law should have no exceptions otherwise the law has failed
This is cyclic change because the population is consistently going up and back down.
The habitat is the kind of natural environment in which a particular organism species lives and it's ability to reproduce determines its niche.
(Prime Example):
Elephants shape their environment in many ways. They can change a forest to a grassy field or dig a hole that might become a pond.
All energy flows linearly; that is, in one direction. There are several basic forms of energy, including kinetic, potential, heat, chemical, electrical, electrochemical, electromagnetic, sound and nuclear.
