3. You are making ampicillin plates. You are given a vial of ampicillin that is labeled as a 1% solution and told that you need to make 40 plates using this solution. Assuming that
you will need 25 mL per plate, what volume of LB agar solution should you make to
prepare the 30 plates? What volume of the 1% ampicillin solution do you need to add to
this volume of LB agar if the final concentration of ampicillin in the plates should be 50 ug/umL?

The answer is atmosphere. there are four spheres of the earth: 1. geosphere (from greek word 'geo' = ground), 2. hydrosphere (from greek word 'hydro' = water), 3. biosphere (from greek word 'bio' = life), and 4. atmosphere (from greek word 'atmo' = air). a magnetosphere is a region of space around astronomical objects controlled by the magnetic field of that object. through the process of elimination, since lightning is present in the air, it can be found in the atmosphere.
