In Response to Moderate Winds, Many Small Spiderlings Climb High

Multiple Choice

In response to moderate winds, many small spiderlings climb high in vegetation and release several strands of silk that form a "parachute." The spider is then lifted into the air by the wind and drifts to a new location, a phenomenon known as "ballooning." Which of the following is true?

A) The movement associated with ballooning would not be considered a behavior because it is not internally coordinated
B) Ballooning would not be considered a behavior because it is not externally visible
C) Spider movement associated with ballooning would not be considered a behavior because it occurs in response to changing conditions
D) The movement associated with ballooning would not be considered a behavior because it is not an activity pattern
E) The movement associated with ballooning would not be considered a behavior because only some spiders exhibit this activity
