The agar plate showed plaques that were all approximately the same size and had the same clear borders so we can assume there is only one phage. If there were plaques of different sizes or clarity, there might be more than one phage present.
Lytic phages are more useful because they immediately infect and kill the bacteria. This makes them more efficient than temperate phages that might delay infection to go through the lysogenic lifecycle.

You explained this super well it was hard to come up with a question. One I had is, what on the agar shows you have 1 phage present?

In your future directions you say that lytic phages are more useful in phage therapy. Why is that?
