I believe the answer is B. They both are found in the nucleus.
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.
The answer is; D
The porous rock is able to absorb water from precipitation. The water resides in the pores of the rock. The impermeable rock later, which does not allow water to pass through it, allows more water to hold in the porous rock and making the local water table to rise. The water in the porous rock, therefore, can be accessed through wells or a water spring can develop.
