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 radioactive element is an element which is subject to spontaneous degeneration of its nucleus followed by the emission of alpha, beta and gamma particles. All elements with atomic numbers greater than 83 are radioactive.
The given phrases that describe radioactive elements are-
They have a consistent number of particles
- the particles are alpha, beta and gamma particles.
They have a half-life that determines their rate of decay.
Explanation for other options:
Not all elements occur in nature. Radioactive decay rates may not be constant as the decay happens when a radioactive substance emits a particle. It is not possible to predict exactly when a given atom of a substance will emit a particular particle. When the radioactive element release energy and particles, it decays.
Charlidamelio is overrated
conduct research on the types of organisms that live in the ecosystem you choose -
Ecosystems, or biological communities, comprise both living organisms such as animals, plants, insects, and microorganisms and nonliving components such as rocks, soil, water, and sunshine.
- Producers are plants and algae that manufacture their own sustenance.
- Herbivores eat plants and are classified as main consumers.
- Secondary consumers are carnivores that devour herbivores at the third level.
- Tertiary consumers are predators that consume other carnivores.
