MBI 111 LAB FINAL ACTUAL QUESTIONS AND ANSWERS
WITH COMPLETE SOLUTIONS VERIFIED GRADED A+
2025/2026
Terms in this set (68)
biofilm complex groups of microbes that
grow on many types of surfaces--
especially difficult to treat w/
antibiotics
biofilm benefits water purification and nutrient cycling
biofilm problems can form on medical equipment (catheters)
and cause UTIs
good biofilm places that stay moist or have water-air
sample spots interference
why might biofilms some environments are different,
grown from some are cleaned more, kept at
different locations different temperatures, and
look different? different biofilms need different
habitats

why might the locations may have similar
biofilms from characteristics suitable for similar biofilm
different location growth
look similar?
UV light effect on UV light causes physical damage to the
bacteria DNA molecules--thymine dimer
a covalent bond is formed between
thymine dimer the neighboring thymines and the
double helix of the DNA is distorted
inhibiting critical enzymes for
copying/transcribing the DNA
proteins
UV light uses germ control in labs, surgical suites, and
water treatment plants
pathogens microbes capable of causing disease
selective media inhibit growth of certain types of
bacteria-- used to help isolate
bacteria from environmental
samples and patient specimens
differential media allow a type of bacteria to be
differentiated from the rest--
medium or colony will change color
as the bacteria grow
