Question 1 - 10
• You should always be aware of and follow
these in a lab.
Answer 1 – 10
• What are lab safety rules?
Question 1 - 20
• A hypothesis is a proposed scientific
explanation based on prior knowledge. A well
tested explanation that unifies a broad range
of observations is this.
Answer 1 – 20
• What is a theory?
Question 1 - 30
• Scientists are always observing a doing this. It
is the first step of the scientific method.
Answer 1 – 30
• What is asking questions?
Question 1 - 40
• This type of variable refers to what is observed
or measured in an experiment. It changes in
response to the manipulated variable.
Answer 1 – 40
• What is the responding variable?
Question 1 - 50
• In an experiment, this is the variable that you
purposefully change. In our rabbit example, it
would be the rabbit who was given the ice
pack.
Answer 1 – 50
• What is the manipulated variable?
Question 2 - 10
• This is the common measurement system
used by scientists. It is based on a scale that
moves by multiples of 10.
Answer 2 – 10
• What is the metric system?
Question 2 - 20
• This is the metric unit of measurement for
mass. We use a triple beam balance to
measure these.
Answer 2 – 20
• What is a gram?
Question 2 - 30
• 71.0 kiloliters is equal to this many decaliters?
Answer 2 – 30
• What is 7,100 decaliters?
Question 2 - 40
• This unit of the metric system is used to
measure the size of very small objects, such as
the length of a cell. It is 1/1000 of a milimeter.
Answer 2 – 40
• What is a mircrometer (nm)?
Question 2 - 50
• These are the seven prefixes of the metric
system. They are represented by KHDUDCM.
Answer 2 – 50
• What are kilo-, hecto-, deca-, base unit, deci-,
centi-, mili-?
Question 3 - 10
• All atoms will have the same number of these
two subatomic particles. Their positive and
negative charges cancel each other out,
making the atom neutral.
Answer 3 – 10
• What are protons and electrons?
Question 3 - 20
• These produces a higher number of H+ ions
when in a solution. They range from 1-6 on
the pH scale.
Answer 3 – 20
• What is an acid?
Question 3 - 30
• This is the attraction between a H atom and
an electronegative atom, such as O. It is the
bond that holds water molecules together.
Answer 3 – 30
• What are hydrogen bonds?
Question 3 - 40
• Weak acids and bases are found towards the
middle of the pH scale, closest to this number.
It is the pH of pure water.
Answer 3 – 40
• What is 7?
Question 3 - 50
• Our bodies need to maintain a specific range
of pH all over, except here, which is much
more acidic.
Answer 3 – 50
• What is the stomach?
Question 4 - 10
• Enzymes speed up chemical reactions, making
them biological ones of these.
Answer 4 – 10
• What are catalysts?
Question 4 - 20
• This macromolecule is made up of a glycerol
molecule and three fatty acids chains. It helps
make up part of the cell membrane.
Answer 4 – 20
• What are lipids?
Question 4 - 30
• These macromolecules give us our main
source of energy, even if it is only for a short
period of time.
Answer 4 – 30
• What are carbohydrates?
Question 4 - 40
• Enzyme function can be effected by drastic
changes in these two internal conditions.
Answer 4 – 40
• What are temperature and pH?
Question 4 - 50
• An amino acid structure contains an amino
group, a carboxyl group and this, which is
different for each amino acid.
Answer 4 – 50
• What is the R-group sidechain?
Question 5 - 10
• These are the two inventors of the
microscope. Without them, we would have
never discovered the cell.
Answer 5 – 10
• Who are Robert Hooke and Anton van
Leeuwenhoek?
Question 5 - 20
• This type of microscope uses a very fine probe
to view the surface of a specimen. You can see
live organisms with it.
Answer 5 – 20
• What is a scanning probe microscope?
Question 5 - 30
• In plant cells, this is the outermost layer,
which provides structure, support and
protection.
Answer 5 – 30
• What is the cell wall?
Question 5 - 40
• These are three structures of the cell
responsible for making and sending proteins
where they need to go.
Answer 5 – 40
• What are the ribosomes, endoplasmic
reticulum and golgi apparatus?
Question 5 - 50
• This is one characteristic of all cells. In
eukaryotic cells it is found in the nucleus. In
prokaryotic cells it is free floating.
Answer 5 – 50
• What is DNA?
