Considering all the changes which have occurred due to reformers we can say that reformers had a positive impact on the problems of American society.
Some of the reformers fought for ending slavery from American society. They had secret meetings in their houses to discuss the reforms that should be taken to finish slavery. Reformers like William Loyd Garrison wrote articles so that people might take slavery as an important issue and help to fight it. The abolutionists movement brought by the reformers has a positive impact and we can see that slavery has been eradicated from American society.
Apart from this, there are many other reforms which have made American society a better place to live.
The best answer is C.Ribosomes are cell organelles or structures that make protein. Ribosomes are found floating in the cytoplasm or attached to the endoplasmic reticulum of the cell.The location of the ribosome will determine what kind of protein it makes. If the ribosome is attached to the endoplasmic reticulum then it will make protein for usage within the cell or outside the cell. If found freely floating in the cytoplasm, then it will make protein that will be used only within the cell and not outside.
