Small colonies are observed at the inner edge of the zone of inhibition around the oxacillin disk when a S. aureus is tested. The outer zone size corresponds to an interpretation of susceptible andthe small colonies are growing in the resistant range. How will you interpret the results, S (sensitive), I (intermediate), or R (resistant)? Explain your answer.
What is a habitable zone (the simplest definition, as used in lectures)? Select one: a. Somewhere where liquid water could exist on a planetary surface b. A region of a planet where liquid water can exist c. A region of space where water is just able to melt d. A region of space where water can exist in all three phases.
A nearly Earth sized planet obits in the habitable zone of Proxima Centauri, the closest star to the solar system. If the orbit is elliptical use either conservation of mechanical energy or conservation of angular momentum to show where in the orbit the planet’s highest and lowest angular velocity occurs. Be sure to show how the rule you choose actually applies to this situation.
Suppose you found yourself living in the habitable zone of planetary system with a dimmer or bringter star than our Sun. What else would be different ? Your location? Available light and heat ? Deadly radiation? What are some of the concerns we have regarding our own Sun?
