Celsius to Farenheit Formula -CORRECT ANSWER C=(F-32)/1.8
Farenheit to Celsius Formula -CORRECT ANSWER F=(1.8XC)+32
or
F=(CX9/5)+32
Convert 1L to ml -CORRECT ANSWER 1L=1000ml (X1000)
Convert 1cm to mm -CORRECT ANSWER 1cm=10mm (X10)
Convert 1$ to cents -CORRECT ANSWER 1$=100cents (X100)
Convert 100ml to L -CORRECT ANSWER 100ml=.1L (/1000)
Convert 10mm to cm -CORRECT ANSWER 10mm=1cm (/10)
Convert 100cents to $ -CORRECT ANSWER 100cents=1$ (/100)
Discrete Data -CORRECT ANSWER (binomial) whole numbers; counting or classifying
into units
Continuous Data -CORRECT ANSWER (approximate) decimals; number which may
fall any place on the number line
Random Error -CORRECT ANSWER due to inherent chance variation and can not be
attributed to any known cause-it's unavoidable and it is evaluated by statistical means
, Systematic Error -CORRECT ANSWER result from some experimental deficiency &
can be described
Illegitimate Error -CORRECT ANSWER error that can be corrected or avoided. e.g bias
How do we express collected data? -CORRECT ANSWER graphical form
Precision-accuracy -CORRECT ANSWER exact measurement
mean (ave.) -CORRECT ANSWER measure of similarities (add all up and divide by
how many)
range -CORRECT ANSWER measure of differences(subtract smallest from largest)
On a graph, what axis would you write weight? -CORRECT ANSWER y-axis

microscope & Electron microscope
What is the difference between a light microscope and an electron microscope?(what
are they best used for) -CORRECT ANSWER Light microscopes are good for
examining living organisms. Electron microscopes are powerful when it comes to
revealing the diverse parts within a cell
Light Microscopes -CORRECT ANSWER pass visible light through a specimen &
magnify cellular structure w/ lenses
what is total magnification? -CORRECT ANSWER multiply the ocular(10x) by the
objective
Electron Microscopes -CORRECT ANSWER focus a beam of electrons through a
specimen (TEM) or onto its surface (SEM)
Two processes of a microscope -CORRECT ANSWER magnification(larger), resolving
power(sharp)
Resolving Power -CORRECT ANSWER the ability of an optical instrument to show two
objects as separate
