BSC 1010L FINAL EXAM QUESTIONS AND ANSWERS
WITH COMPLETE SOLUTIONS GRADED A++
What are the steps of the Scientific Method? Know how to design and carry out
an experiment using the 6 steps of the scientific method.
Observation
Question
Hypothesis
Prediction
Experiment
Conclusion
What are the experimental and control groups?
e: treated with or possess the independent variable
c: not treated or does not possess the independent variable
Control Variable
what remains constant so that you can accurately test the question you set out to
answer (temperature, age of study participants)
Dependent Variable
the variable of interest/response or what you observe as the outcome (growth rate,
death rate)
Independent Variable
,the variable you will be modifying in the experiment (temperature, salinity, dosage)
Know the prefixes and relationships between the units in the metric system
kilo = 10 (3)
hecto = 10 (2)
deka = 10 (1)
base
deci = 10 (-1)
centi = 10 (-2)
milli = 10 (-3)
micro = 10 (-6)
nano = 10 (-9)
0.047 nm to ____ cm
10 (-9) - 10 (-2) = 10 (-7)
so, 0.047 x 10 (-7)
What are the different types of macromolecules and their basic structure? Focus
on what they are made up of
large organic molecules
carbs
lipids
proteins
nucleic acids
, Carbohydrates
composed of carbon, hydrogen and oxygen
monosaccharides, disaccharides, polysaccharides
Monosaccharide
single sugar molecule
glucose
fructose
ribose
Disaccharide
two monosaccharides combined
sucrose
lactose
Polysaccharide
large or more complex carb
starch - plants
glycogen - animals
Lipids/fats
oily or greasy compounds that aren't soluble in water; long term energy storage
saturated fats
