Answer:
Air pollution from smokestacks will be the biggest challenge.
Explanation:
China is one of the biggest producers in the world of agricultural goods. The country has a long tradition of being among the leaders in the world in this sector, even when it has been in terrible conditions. One thing that is a problem though is that the area where agricultural activities take place in China is not that big. This is due to the country's geography.
But it seems that geography won't be the biggest problem, but the pollution of the air. China has become heavily industrialized and in order to reach the level at which it is now, it did not take the environment into account at all. The pollution has constantly been increasing and it affects agriculture as well. Because the air pollution is at a very high level, there are more and more acid rains, but also they partially block the sunlight. The acid rains destroy the plants, which is already causing problems and they will only just increase. By blocking the sunlight in some areas, the plants grow slower and produce less because they cannot perform photosynthesis properly.
Answer:
I would say that the best answer is A.
Explanation:
Both Bacteria and Archaea, lack a nucleus and are unicellular. Most Archaea have a Cell wall, however there are a few exceptions, all Bacteria have a cell wall. Maybe the biggest difference between the two however, is where they thrive. Archaea live in extreme conditions, while bacteria don't. Due to this, I would say that the best answer is A, because this is the only question with a major difference in answers.
The biggest reason for that her work is a success is because new ideas often develop from unsuccessful experimentation.
The scientific process not only relies on proper experimental methods and determination, but it also is dependent on the failures of the experiments of scientists. When experiments fail, other scientists obtain a guideline of what to do and what not do. This improves their own experiments and helps them move forward.
I feel the producers are the most important, because if they collapse, soon the plant eaters will collapse, then the animals that eat them, and so on.
You could also say A scavenger is the most imporant because without them we wouldnt be ŕecycling´ food.
