BIRD MIGRATION
Refer to “Bird Migration” below. Click the letter to answer the question.
Most migratory birds gather in one area and then migrate in large groups rather than individually. This behavior is a result of evolution. Which of the following is the best scientific explanation for the evolution of this behavior in most migratory birds?
Birds that migrated individually or in small groups were more likely to find adequate food.
Birds that migrated individually or in small groups were less likely to survive and have offspring.
Flying in large groups allowed each bird to have a better chance of finding a nesting site.
Flying in large groups allowed other bird species to join the migration.

SLOPE- FACE INVESTIGATION
Data Analysis
A group of students noticed a dramatic difference in the vegetation on the two slopes of a valley: the vegetation is much greener and more abundant on slope A than on slope B. This difference is shown in the illustration on the right.
The students investigate why the vegetation on the slopes is so different from one slope to the other. As part of this investigation, the students measure three environmental factors over a given period of time:
Solar radiation: how much sunlight falls on a given location
Soil moisture: how wet the soil is in a given location
Rainfall: how much rain falls on a given location
The students take the average of the measurements collected over a given period of time from each pair of instruments on each slope and calculate the uncertainty in these averages. Their results are recorded in the following table. The uncertainty is given following the "士 " sign.
