Answer: All plasma membrane surfaces are hydrophilic. In comparison, because of the fatty acid tails, the interior of the membrane between its two surfaces is a hydrophobic or nonpolar region. The main fabric of the membrane is composed of two layers of phospholipid molecules. The hydrophilic or "water-loving" areas of these molecules are in contact with the aqueous fluid both inside and outside the cell. Hydrophobic, or water-hating molecules, tend to be non-polar.

I have chosen Slavery for the answer.
Explanation:
America has long been a prosperous country. In the olden days, the Southern states relied on tobacco, cotton and sugarcane for their economy. These were fueled by human labor or the so-called "slavery."
During the start of the Civil War, the South was producing 75% of the world's cotton and created more millions for the nation. They deeply relied on their most significant investment, the<em> Southern planters (the slaves).</em> <u>Slave labor has become so entrenched until the beginning of the 19th century.</u> By this time, slavery and cotton were essential part of the American's economy.
However, the <u>Abolotionist movement</u> gained influence in the Congress. This was an organized effort in order to end the practice of slavery in the USA. This created an economic pressure on the South, which heavily relied on slavery. People from the South provoked the movement because they believed that most slaves have no desire for freedom. This became an emotional and political issue. It divided much of the country. The <em>Atlantic Slave Trade</em> was also affected. This was involved in the transportation of the enslaved African people, mainly to America.
