1. Statistical analysis of data from field Further experimentation or obser-
experiments supports the conclu- vation could still discredit the hy-
sion that an investigators hypothesis pothesis
about the role of seas stars in an inter-
tidal community is valid. Which of the
following statements is true?
2. In which of the following cases would comparing the percentage of sev-
a circle graph be the most appropriate eral types of prey in the diet of an
format for presenting data? owl species
3. The graph above depicts the num- starting the scale on the vertical
bers of three different species of ants axis at zero
counted in a field study. Which of the
following adjustments would provide
the best presentation of the field study
results?
4. A lab exercise requires the separation centrifugation
of cells form the liquid culture medi-
um they have been grown in. Which of
the following lab procedures would be
most effective at achieving this sepa-
ration?
5. In a bird species, the percentage of y axis up slopes down to x axis big
young successfully raised by the par-
ents each year tends to be inversely
proportional to the number of eggs
laid. Which of the following graphs
best represents the type of data on
which this statement is based?
6. two bird species regularly visit feed- observing the feeding behaviors of
ers for sunflower seeds during the both species under natural condi-
winter. For a month, several students tions
take turns watching the feeding sta-

and record their observations. They

find that whenever individuals of one
species arrive at the feeder, individ-
uals of the other species leave. The
students conclude that competition
for food between the species is im-
portant factor in their ecological re-
lationship. The students conclusion
above would be most strengthened
by adding which of the following ele-
ments to their study?

ford and his colleagues performed an the mass of an atom is concentrat-

were directed at a thin sheet of gold
