Answer:
D
Explanation:
If NASA had constructed a Space Shuttle without knowing if it would be safe for its passengers, there could be many casualties. So they would test it beforehand using a model, to make sure that it will be safe and sturdy for when they build it.
Ponds can develop self containing ecosystems.
The global population is growing, but in the coming decades the population will start to stabilize.
Explanation:
From the presented graph, we can see that the world population is expected to continue to grow in the coming decades. That is not to say that it will never stop, as the prediction are that around 2050 the population should start to stabilize. Also, it can be seen that the growth is expected to gradually slow down on global level. The main reason behind the expectations of growth that will slow down and stabilize is that the development, and the more developed a country gets, the lower the birth rates tend to be.
- Europe is the only continent that is expected to actually experience decline in its population.
- Africa is the only continent with significant growth of its population.
- The rest of the world is either entered or is expected to enter a stabilization phase and have pretty much no growth.

Researching unaltered ecosystems helps scientists in many ways. There is a lot of Methodology and very precise data that needs to be collected, but I'll just try to gloss over the main points.
Questions on landscape ecology, behavioral ecology, ecosystem dynamics, community ecology and nutrient cycling are reviewed in the process. But this helps scientists with figuring out with what issues need to be solved and how the modern world affects these unaltered ecosystems. It can also help scientists possibly find new forms of life, even to the microscopic level since the ecosystem is unaltered. Finally, it also helps track animal movements if that data is needed.
Hope this helps! Feel free to message me if you need more help or if oyu have any questions! :)
