The oil produced in United States is light and low sulfur content and they do not have proper processing facilities, hence purchase it from other countries.
Explanation:
About 9.93 million barrels per day U.S purchase oil from 86 countries. Because the crude oil present is not homogeneous in nature. It is very light in nature with low sulfur content or may be high,this particular factor depends upon the method of the refining.

Answer:
The level of specialization is given by the function.
The function of the organ makes the cell as it becomes mature, its more specific function becomes.
First, a stem cell differentiates itself into a hepatic or neuronal cell, thus generating that its functions are limited compared to the rest of the stem cells.
After this process, throughout the cell development and maturation of the organ, its cells become more specific in a single activity.
Explanation:
The differentiation of the stem cells is regulated by the genetic code, the migration of these during the embryonic stage of the mouse and the external stimulation that these stem cells perceive.
Both fungi and bacteria are very important for decomposition of organic matter. Decomposition is the break down of dead or decaying organisms. This allows nutrients from all trophic levels to re-enter the soil to be used by primary producers. Fungi are more effective decomposers compared to bacteria as they can <span>use their hyphae to penetrate larger pieces of organic matter, whereas bacteria are restricted to exposed surfaces. </span>
