Question

multiple choice question
structures located within the nucleus of a cell which function to regulate all activities of the cell ______.

○ chromosomes
○ ribosornes
○ peroxisornes
○ lysosornes

Explanation:

To solve this, we analyze each option:

• Chromosomes: Located in the nucleus, they carry genetic information (DNA) that regulates cell activities.
• Ribosomes: Found in cytoplasm (or on ER), involved in protein synthesis, not in nucleus for regulation.
• Peroxisomes: Organelles for metabolic reactions (like breaking down fatty acids), not in nucleus.
• Lysosomes: Contain digestive enzymes, in cytoplasm, for breaking down waste, not in nucleus.

So chromosomes are in the nucleus and regulate cell activities.

Answer:

chromosomes (the option with "chromosomes" text)
