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.

Answer:
Brown dwarfs are objects which are too large to be called planets and too small to be stars. They have masses that range between twice the mass of Jupiter and the lower mass limit for nuclear reactions (0.08 times the mass of our sun). ... Brown dwarfs are very dim and cool compared with stars.
Explanation:
Beets, carrots, turnips, onions, radishes, and (the odd one out) celeriac.
Answer:
The simultaneous effect of a predator population on a prey population and a prey population on a predator population over time.
Explanation:
The mathematical models of Lotka-Volterra equations explain the existing interaction between species in which prey and predator influence and affect each other. The model follows a few assumptions,
- The ecosystem is isolated and closed. There is no migration.
- The whole individuals are reproductively equivalent.
- In the absence of the predator, prey shows an exponential growth rate. The prey is in the ideal environment.
- When there is no prey, the predator population decreases exponentially because of the lack of food. The predator environment is ideal, but it is limited by prey density.
- The predation rate is proportional to the encounters rate, which also depends on density.
- The predators affect the prey populations, inducing its decrease proportionally to the number of prey and predators present.
- The prey population also influences the predator population proportionally to the number of encounters between the two species.
In these equations, the variable D is the number of predators, and P the number of prey items.
The parameters are always constant:
• r1: prey growth rate.
• a1: predator hunting success.
• r2: predator growth rate.
• a2: the success of the predator in hunting and feeding.
In nature, many factors affect interactions, such as dense-dependent factors and dense-independent factors. Also, in reality, there are stochastic factors. Stochasticity refers to the variability in the system involving those factors that are affecting or influencing population growth. Stochasticity might be related to good years and bad years for population growth.
In real situations, the compliance of the whole assumption does not occur. The previously mentioned constants might vary, constantly changing the interaction between the predator and the prey. These parameters change in different degrees, resulting in varying circumstances for both species.
