Q1. Imagine yourself to be a bacteria or a virus and you require establishing infection in an organ of your choice.

Discuss how you would revise the plan of survival if your symbiotic relationship changes; either from mutualistic to commensalistic, or from commensalistic to mutualistic.

Q2. Many "leftovers" from planetary formation were likely ejected from our solar system, and the same has presumably happened in other star systems. Given that fact, should we expect to find meteorites that come from other star systems? How rare or common would you expect them to be?

(Be sure to consider the distances between stars.) Assume that we did find a meteorite identified as a leftover from another stellar system. What might we learn from it?
