which structure produce, process, and transport proteins within the cell?

D.

D is rough endoplasmic reticulum present in the cell. This structure is responsible for production, processing and transportation of protein within the cell. The endoplasmic reticulum is the organelle which remains attached with nuclear envelop. The rough endoplasmic reticulum is studded with ribosome. The ribosome causes specific RNA molecules to pass through the endoplasmic reticulum and results in protein synthesis. The proteins being synthesized are transferred from endoplasmic reticulum to other parts of cell or out 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.
