It is B
Explanation:
I had this question on my test last week.
The best answer would be letter D. C<span>ompare the average number of tomatoes that are produced by 10 tomato plants that are grown in clay soil to the average number of tomatoes that are produced by 10 tomato plants that are grown in sandy soil.
It would be best to grow more than one tomato plant in each soil to truly represent the tomato's growth in them. To average the number of tomatoes yielded by each soil sample would also allow a sample that is more representative of the tomato plants than merely comparing single tomato plants.

So you know that there are 3,000,000 of bacteria in one gram of soil so you multiply 3,000,000×10 and you get 30,000,000. Then you just check all your options. So it's 3×10^7.
When you do that the fish will die. That is because it will take too much water in it and die from it, or rather, the fish's cells will take too much water in.
Chloroplasts and mitochondria are organelles found in plant cells. Chloroplasts contains the cholrophylls while the mitochondria is the powerhouse of the cell where energy is found. In this case, the two organelles not only have inner membranes but also their own DNA and ribosomes
