BIO 150 Lab Week 2 Question andanswers verified to pass (7 pgs)
Match each sentence from the example proposal summary paragraph in your
lab manual to the typical part of a research proposal that BEST represents
this sentence. (Some choices will NOT be used).
Roughly 70% of the American population eats avocados at least once each
year, so that potential exposure of the populace to contaminants in avocados
is widespread
Nonetheless, little research has been done with regard to the uptake of trace
metals by avocados during their growth
We will test the hypothesis that concentrations of Hg and Cd in avocados are
correlated with the levels of these trace metals in the surrounding
groundwater. The proposed research would address this problem by making
the first detailed examination of the controls on concentrations of trace metals
in avocados
Specifically, groundwater in 15 groves of avocados will be sampled and
concentrations of trace metals determined by atomic absorption - correct
answer ✔
