Answer:These questions are related to a specific experiment or model that you have not provided. To answer them accurately, I need more information about the experiment or model you are referring to. Please tell me: - What was the experiment or model you were working with?- What were the materials or components used?- What were the steps involved in the experiment?- What observations did you make during the experiment? Once I have this information, I can help you answer the questions about the similarities and differences between the model and reality, the relationship to the Big Bang theory, the meaning of the dots, and the changes in distance.HOPE IT HELPS YOU
