Explanation:

The nucleus is the control center of the cell. It contains the cell's genetic material (DNA), which carries hereditary information. This DNA is crucial for the cell's functions, growth, and reproduction. The nucleus protects this DNA and regulates its expression.

• The first option (regulating cell temperature) is incorrect as there is no such function associated with the nucleus.
• The second option (providing structure and aiding cell movement) is more related to the cytoskeleton.
• The fourth option (packaging waste) is a function of the Golgi apparatus.

Answer:

The nucleus protects and regulates the hereditary information for the cell.
