Living organisms are composed of millions of organic compounds, each having a unique structure. what element is responsible for this huge diversity of molecules? describe the diversity of structures that can be formed and the properties of this element that allow this diversity of form to occur

The answer is carbon.

The reason this element gives so much diversity is due to its valency of +4. This means it can bond with many elements in different ways to form different compounds. Carbon can also bond with other carbon atoms in many different ways (from linear chains, branched chains to rings). It is due to this versatility that carbon is the central elements of organic life. The different organic molecules that carbon is the central atom is DNA, carbohydrates, proteins, lipids, and etcetera.  

americans began to notice growing differences between the northern and southern sections of the country. there were more people living in cities in the north, which made it more urban. more people lived on farms in the south, which made it more rural. while many people were farmers in the northern states, there were now other ways to make a living, such as working in mechanical cotton gins factories manufacturing cloth, tools and other goods. people in the north supported high tariffs on goods imported from europe because the extra cost encouraged people to “buy american” instead. in the southern states, planters did not like tariffs because they sold most of their production to europe and bought their tools from there as well. southerners believed the protective tariff was something that only northern factory owners keep their profits high. so the southern politicians came up with an idea. they would opt out. they would simply ignore the protective tariff. it was ‘null and void’ in south carolina. the state would not collect the taxes on goods imported into south carolina, no matter what the president said they had to do. this decision led to the nullification crisis.
