**Question 3:**A student performs an experiment similar to the one performed by Luria-Delbruck. However, the writing on the tubes became smudged. Which of these experiments supports the fact that mutations are spontaneous? Why?**Diagram Description:**The image contains two sets of experimental steps. **Left Side:**1. **Steps 1-3, up to 100:** - Test tubes labeled from 1 to 100 with arrows indicating growth in a nonselective medium.2. **Isolation and Culture:** - Isolation of microcolonies and culture in a selective medium. - Depicts a series of Petri dishes showing small, consistent colonies.**Right Side:**1. **Steps 1-3, up to 100:** - Test tubes labeled from 1 to 100 with arrows indicating growth in a nonselective medium.2. **Isolation and Culture:** - Isolation of microcolonies and culture in a selective medium. - Depicts a series of Petri dishes showing varying colony sizes.**Explanation:**The right side of the diagram illustrates the occurrence of spontaneous mutations. The variation in colony sizes on the selective medium suggests that mutations occurred at different times, leading to different growth advantages. The left side, showing consistent colony sizes, suggests that mutations were induced by the environment rather than occurring spontaneously.

Experiment 1 shows that mutation are spontaneous and arise during cell division. This is the reason…
