Question

Which of the following implies movement with regard for direction?  
A) Taxis only
B) Kinesis only
C) Migration only
D) Taxis and migration only
E) Taxis, migration, and kinesis

Accepted Answer

Taxis and migration both imply movement with regard to direction. Taxis is a directed movement towards or away from a stimulus, and migration is a seasonal or periodic movement of organisms from one place to another for feeding, breeding, etc. Kinesis, on the other hand, is a non-directional response to stimuli.
