The right option is; D. Made of cells.

chuck said it could not be any living thing because it was not made of cells.

Cell is the basic structural and functional unit of all living organisms. All living organisms are made up of many cells that functions together, and they are either unicellular or multicellular organisms. Cells contain several membrane bound organelles that perform different important functions within the cell. Distinct features that allow a cell to carry out its functions include; a cell membrane that keep the chemical reactions of life together, at least one chromosome that contains genetic material, and the cytoplasm (the content of the cell).

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.

the function of the protein macromolecule is to move things in and out of the cell and transport other molecules in the body. there are many functions of proteins. they are the basic building blocks of living things and are responsible for the growth and repair of body cells and tissues.
