A taxis (from Ancient Greek τάξις (táxis) 'arrangement, order'; [1] pl.: taxes / ˈ t æ k s iː z /) [2] [3] [4] is the movement of an organism in response to a stimulus such as light or the presence of food. Taxes are innate behavioural responses.
Kinesis, like a taxis or tropism, is a movement or activity of a cell or an organism in response to a stimulus (such as gas exposure, light intensity or ambient temperature). Unlike taxis, the response to the stimulus provided is non-directional.
Chemokinesis is chemically prompted kinesis, a motile response of unicellular prokaryotic or eukaryotic organisms to chemicals that cause the cell to make some kind of change in their migratory/swimming behaviour. Changes involve an increase or decrease of speed, alterations of amplitude or frequency of motile character, or direction of migration.
Energy taxis is the orientation of bacteria towards conditions of optimal metabolic activity by sensing the internal energetic conditions of cell. Therefore, in contrast to chemotaxis (taxis towards or away from a specific extracellular compound), energy taxis responds on an intracellular stimulus (e.g. proton motive force , activity of NDH- 1 ...
Run-and-tumble motion is a movement pattern exhibited by certain bacteria and other microscopic agents. It consists of an alternating sequence of "runs" and "tumbles": during a run, the agent propels itself in a fixed (or slowly varying) direction, and during a tumble, it remains stationary while it reorients itself in preparation for the next run.
Fixed action pattern" is an ethological term describing an instinctive behavioral sequence that is highly stereotyped and species-characteristic. [1] Fixed action patterns are said to be produced by the innate releasing mechanism, a "hard-wired" neural network , in response to a sign/key stimulus or releaser .
Waymo's robotaxis have started occupying a new San Francisco lot at night. Nearby residents are finding the self-driving cars honk, for some reason, at each other, often waking them up.
Chemotaxis (from chemo-+ taxis) is the movement of an organism or entity in response to a chemical stimulus. [1] Somatic cells , bacteria , and other single-cell or multicellular organisms direct their movements according to certain chemicals in their environment.
