Question: Explain how DNA, which is six feet long, can be stored in the nucleus of a tiny human cell.
Answer: Humans make diagrams/models of DNA which can be six feet long. In the nucleus of a tiny human cell, it is much smaller causing it to be able to fit perfectly in a human cell. Humans make the diagrams/models of DNA to have a better look at what DNA looks like, and to show other humans what it looks like. Scientists also use the diagrams/models to study DNA.
Question: Is science and social studies the same thing?
Answer: History, sociology, political science, and economics are social sciences. 'Social studies' is a bit of a vague term which can include (partial) study of all of the above.
Or, in other words: Social studies is the integrated study of the social sciences, humanities and history.
