Quote
of the week:
But science is one of the very few human
activities-perhaps the only one- in which errors are systematically criticized
and fairly often, in time, corrected. This
is why we can say that, in science, we often learn from our mistakes, and why we
can speak clearly and sensibly above making progress there.
-Karl Popperm from Conjectures and Refutations
Question
of the week: What family of bacteria is known for causing damage on famous
monuments and sculptures due to its strange eating habit of eating marble and
converting it into plaster?
Answer to last week's question:
What
freshwater mammal is venomous? The
male duck billed platypus has venomous spurs located on its hind legs.
When threatened, the animal will drive them into the skin of a potential
enemy, inflicting a painful sting. The
venom this action releases is relatively mild and generally not harmful to
humans.
Unit
2:Microscopy, Microbial Cell Biology and Enzymes (Ch3,
4,and first part of Ch 6)
CONCEPT:
MICROSCOPY
-parts
and functions of the compound light microscope
(
eyepiece, objective, fine adjustment, coarse adjustment, diaphragm, body tube,
etc.)
(total
magnification)
-measurements
in microscopy ( millimeter, micrometer and nanometer)
-role
of the oil immersion lens
CONCEPT:
ISOLATING BACTERIAL GROWTH
-pure
culture
-mixed
culture
-streak
plate method
CONCEPT:
PREPARING BACTERIAL SLIDES
-bacterial
smear ( heat fixing, simple stain)
-gram
stain
-gram
positive bacteria
-gram
negative bacteria
-peptidoglycan
cell wall
CONCEPT:
SHAPE OF BACTERIAL CELLS
-cocci
-bacillus
-spirilium
-vibrio
-spirochete
CONCEPT:
ARRANGEMENT OF BACTERIAL CELLS
-"diplo"
as in diplococci
