Answer:
probably tectonic plates would shift
the answer is d. break down matter from dead plants and animals
Answer:
The correct option is C. Building a well between the two wells that goes deeper into the earth would not stop the water from being polluted .
Explanation:
Even if a well was constructed between the wells B and C, it wouldn't have stopped the contamination of the water. As the oil would still be leaking and it would contaminate the wells.
All of the other options can be used to stop the contamination.
Option A suggests building an impermeable membrane that would stop the oil flow. Hence, the water in the wells will not be contaminated.
Option B suggests not using the water from the wells and using an alternate water supply. The alternate water supply wouldn't be contaminated with oil.
Option D suggests chemically purifying the contaminated water. This can be an effective technique to clean the contaminated water.
Some scientists hypothesize that the eukaryotic cells are really the result of symbiotic processes!
Specifically, the internal organs of the cells could be a remnant of a symbiotic relationship in which one cell lived inside of another cell. These two cells then both split upon reproduction and eventually the cell inside was reduced to an organelle.
But according to this theory, it is very likely that the prokaryotic cells engaged in a number of symbiotic relationship, and that this actually lead to the emergence of eukaryotic cells!
