Answer:
a: taxis
Step-by-step explanation:
Living organisms exhibit innate or intrinsic response to the their environment in order to ensure continuous survival in that environment. Depending on the organisms, responses to external stimuli or environmental factors differ and can be categorized into 3 classes namely;
- Tropism: the turning of all or part of an organism towards or away from external stimuli. When the turning is towards the stimulus, it is positive, otherwise it is negative.
- Kinesis: a non-directional movement of organisms in response to external stimuli.
- Taxis: a guided movement of an entire organism to or away from external stimuli.
