A urine sample with more than 100,000 organisms is considered indicative of infection. A urine sample containing 5,000 bacteria, with a generation time of 30 minutes, sits for 3 hours before finally being assayed.  How many bacteria will then be present within the sample?  [Nf = (Ni)2n]

A newly described unicellular organism was isolated from a salt mine. This organism has no membranous organelles and its cell wall lacks peptidoglycan. Attempts to culture it in a medium with less than 25% salt were unsuccessful, but it was able to grow well on 25% salt supplemented agar. This organism is most likely in the domain ___________.
