GRAPHS:
A scientist wanted to observe the effects of
altitude on the respiratory system of mammals.
Four different species of mammals were placed
in a chamber that underwent gradual changes
in pressure (measured in atmospheres, or atm)
to simulate the atmosphere at high altitudes.
After 5 minutes at each atmospheric pressure
tested, the average number of breaths per
minute (respiratory rate) was determined for
each of the 4 mammals while they remained at
rest. The data from the experiment are shown
in the following graph. (Note: Larger animals
typically have slower respiratory rates. Higher
respiratory rates indicate rapid breathing, a sign
of distress in some animals.)
10. According to the data in Figure 1, as the
atmospheric pressure decreases, the respiratory rate for mammal 1
a. Increases
b. Decreases
c. Increases then decreases
d. Decreases then increases
How to perform skill in a graph:

Circle anything in the question that tells you which data sets you are considering
Locate these pieces of information in the graph
Determine the direction you should read the graph from the information in the question
Trace the data line according to the direction given in the question.
Find the trends in the graph
11. According to the data in Figure 1, as the atmospheric
pressure decreases, the respiratory rate for mammal 2
a. Increases
b. Decreases
c. Increases then decreases
d. Remains about the same then increases
12. According to the data in Figure 1, as the atmospheric
pressure increases, the respiratory rate for mammal 3
a. Increases slightly
b. Decreases slightly
c. Increases then decreases
d. Decreases then increases
13. According to the data in Figure 1, as the respiratory rate
for mammal 1 decreases, the respiratory rate for
mammal 4
a.
b.
c.
d.
Increases only
Decreases only
Increases then decreases
Decreases then increases
14. What is the relationship between respiratory rate and
atmospheric pressure for mammal 2?
a. Decreases in pressure decrease the respiratory
rate.
b. Decreases in pressure increase the respiratory
rate.
c. Pressure changes have no effect on the
respiratory rate
d. Increases in pressure increase the respiratory
rate
