Answer is B. The number of the question that should be considered next. Let's say your organism has a dorsal fin, then you would go to 5. Then you choose a or b depending on the location of the tail. Let's choose 5a for now. Across from it says 6, so you go to 6
All of the above.
Water is essential, you can only survive an average of 3 days without it. (some people have survived for longer though.)
Water is important for shipping and trade, because, ships. They go across water. Trade happens. It's hard to fit a lot in airplanes and you have to monitor it's weight slowly. Across land, it's also hard to fit a lot in random trucks driving across what was an ocean. (it would also be much more tedious) It's also one of the cheapest ways.
It is, I guess. There is a high demand for water, and a limited amount as well. It would also be profitable because you can get water easily, or something. (I don't really know for this one but the other two are true so I guess you can't select two so yeah.)
I would say b or at least that’s what it was on my test
The number of new cases of a particular disease contracted within a defined population in a specified period is referred to as the incidence of the disease.
Population is defined as a group of similar type of organisms. This group of organisms live in the same area, they require same resources, have similar types of habits. The most essential criteria is that they can breed and reproduce among themselves.
Incidence of a disease is the data that provides information about the number of people affected by a disease at a given period of time. The likelihood of a person getting affected by the disease can be estimated using incidence.
