AICE MARINE SCIENCE COMPREHENSIVE
TEST PAPER QUESTIONS AND VERIFIED
ANSWERS REVIEW SHEET
●● outlining/designing an experiment
Answer: -state amount of containers e.g. 5 tanks of each
-state constants (at minimum 3) (light, salinity, amount of water, how
often results are calculated, amount f exposure/days etc.)
-what is the amount of independent variables used? pick a quantity
suitable for the experiment appropriate to the experiment
-state the duration of the entire experiment
-state the calculating results. most common is simple counting
-state repeat experimentation and calculate mean/average from all trials
●● describing results of an experiment
Answer: -state the most with reference to data
-state the least with reference to data
-manipulate data by finding range
●● creating or working with graphs
Answer: -use the entire graph
-correctly label the x and y axis
,-use correct intervals. do not use breaks to begin at certain number. each
interval is equally spaced. use appropriate scale the divide the total
number of spaces on the graph by the range. this will give you your
interval.
-when constructing a graph, make sure your scale is appropriate to show
a relationship-you may need to have values on the axis to the left and to
the right
-plot all points correctly
-line of best fit
●● explain what would be needed to turn an experiment into a theory
Answer: -rigorous testing
-repeated testing by many/other scientist
-scientist get similar results but with the same conclusions no exception
●● symbiosis
Answer: remember that aice looks at symbiosis and mutualism one in
the same. it is a close relationship between 2 different species where
both benefit. make sure you explain what both are getting/giving.
examples: coral and zooxanthellae; tube worms and chemo. bacteria
●● arrows in a food chain
Answer: or food web represent: transfer engery and biomass
-do not use the words "eats," instead, use consumes
, ●● predator/prey relationships
Answer: remember that the number of predators lags behind the number
of prey organisms
●● succession
Answer: tube worms, remember =, tevnia first, the they are replaced by
riftia
●● extreme and unstable
Answer: explain why extreme and unstable environments have low
biodiversity
first, define terms: extreme, unstable, and biodiversity
second, give examples of each environment with organism's adaptation
to that environment
●● extreme environments
Answer: have a low ph, high temperature, low oxygen and high salinity
-extreme environments have limited resources
-hydrothermal vents are an extreme environment
-example of an organism at a hydrothermal vent is chemosynthetic
bacteria
