Given a scientific passage and an answer, generate a question for the given answer.

Input: Consider Input: Passage: The Prokaryotic Cell Recall that prokaryotes (Figure 22.10) are unicellular organisms that lack organelles or other internal membrane-bound structures. Therefore, they do not have a nucleus but instead generally have a single chromosomea piece of circular, double-stranded DNA located in an area of the cell called the nucleoid. Most prokaryotes have a cell wall outside the plasma membrane. Answer: nucleoid

Output: Prokaryotic cells do not have a nucleus but instead generally have a single chromosome, a piece of double-stranded dna located in an area of the cell called the what?

Input: Consider Input: Passage: and . The electric force is 39 orders of magnitudes bigger. Answer: 39

Output: How many orders of magnitudes bigger is the electric force?

Input: Consider Input: Passage: Enzymes are proteins that speed up biochemical reactions in cells. Antibodies are proteins that target pathogens for destruction. Answer: enzymes
Output: What are the proteins called that speed up biochemical reactions in cells?
