Bio lab final
Advantages and disadvantages of viewing live specimen - CORRECT
ANSWER-Observe motility, but can move off focus
Coarse adjustment knob - CORRECT ANSWER-Larger, initial focusing
Control for confounding variables - CORRECT ANSWER-
Crenation - CORRECT ANSWER-cell shrinking
Effect of pH on the O2-Hb Dissociation Curve - CORRECT ANSWER-highest activity
at optimal pH of around 7
Example of what would decrease the chi square value - CORRECT
ANSWER-increasing sample size
Examples of what would increase the chi-square value - CORRECT
ANSWER-increase in deviation, increase in number of data classes
Fine adjustment knob - CORRECT ANSWER-Final focus, slight movement
Guaiacol - CORRECT ANSWER-used to create a color to detect amounts of
peroxidase activity in samples (brown is oxidized vs clear is reduced)
