<span>Composition. (We use the crust-mantle-core terminology to describe differences in chemical composition in Earth's interior. We use the lithosphere- asthenosphere terminology to describe differences the physical state and behavior. Note that the boundaries between layers with different compositions do not occur at the same depths as the boundaries between layers with different physical properties. For example, there is a change in composition when passing from crust into mantle. But there is no change in physical state or behavior at this boundary- the uppermost part of the mantle behaves in the same way that the crust does because it is still far enough below its melting temperature to be a rigid, brittle solid. The transition to a softer, more pliable solid occurs further down within the mantle and this change in behavior occurs with no change in composition.)</span>
The correct answer is : Open Ocean
Since the open ocean is really far from the land soil, the water consist almost no nutrients . And since it's really far away from the coast, there's almost no productivity around here ( almost no human is brave enough to go to the open ocean)
Answer:
They are not violent killers because they need their host to stay alive for their benefit And if the host dies the parasite wont have a host so they try to keep it alive for as long as possible.
Explanation:
Well you know sometimes you see a lot of small bridges that will have weight limit signs. I believe this is really for safety precautions. Keyword: SMALL bridge -
Due to some bridges being small, the materials and strength of the bridge may not can withstand a certain weight. The contents of the vehicle, axels, and wheels, all add to that weight. So there is a very good reason for that to matter.
I hope my somewhat, tied together answer provides just the information you need!

Answer:
c) A study of how disease rates vary among different population groups
Explanation:
Epidemiology is the systematic and scientific study of the distribution of the health-related issue in a specified population.
The Epidemiologists studies the disease and its cause in a population by the collection of the data which gives an insight in the distribution of the health issues in the population living from a small area like school to a country.
The epidemiological studies help the society by reducing the risk of the negative health outcomes, in spreading awareness about the health issues and in framing the health policies.
Thus, Option-C is the correct answer.
