✔✔What is human body temperature in F? - ✔✔98.6 F
✔✔How are the metric units for LENGTH and VOLUME related? - ✔✔1 cubic
centimeter [cc, cm3] = 1 ml
1 cubic decimeter (1dm3) = 1 L
✔✔What is a micrometer? - ✔✔A micrometer is a unit of LENGTH measurement in the
metric system
equal to 1,000,000th of a meter. (one-millionth, 0.000001, 10-6)
✔✔What is a MENISCUS and what is the "MENISCUS RULE"? - ✔✔The MENISCUS is
the CONCAVE surface depression in the
surface of water in a GRADUATED CYLINDER or PIPETTE.
The MENISCUS RULE states that you should read the volume
at the BOTTOM of the meniscus.
✔✔Why would you push the TARE button on the digital balance?
EXPLAIN how this TARE technique could help you to avoid doing some MATH (!). -
✔✔To zero out the balance if it's not reading zero
Remove the weight of
weighing paper or weigh Boat from your measurement.
,✔✔What is an atom or molecule? Why do biologists need to know about Atoms and
molecules? - ✔✔-An atom is the basic "building block" of all matter
-Because all organisms are made of atoms (and molecules)
-Because they are the building blocks of life
✔✔A researcher decides to study if ALKA SELTZER dissolves faster in DISTILLED
water or TAP water.
What is the INDEPENDENT VARIABLE?
What is the DEPENDENT VARIABLE? - ✔✔-IV: type of water
-DV: time to dissolve
✔✔HOW MANY covalent bonds does CARBON form - ✔✔4
✔✔LABEL the following statements with an H if they are hypotheses and P if they are
predictions
____ If the null hypothesis is "true", then when we dissolve one tablet of generic alka
seltzer In 250 mL of water at 50C and do the same for 350C, there will be no difference
in the Time to dissolve in both beakers.
____ There is a measurable difference in the IQ of dogs and cats and cats are smarter.

Name one specific hormone that is made by this organ and explain what it does. - ✔✔-
Pancreas
-INSULIN: when released, it stimulates cells to absorb glucose and this will decrease
blood glucose
