The directed movement of a motile cell or organism in response to an external stimulus. Any process that modulates the frequency, rate or extent of a response to an external stimulus. Any process that activates, maintains or increases the rate of a response to an external stimulus. Any process that activates, maintains or increases the rate of a response to a stimulus. Response to stimulus is a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a stimulus. Any process that activates or increases the frequency, rate or extent of a biological process. Biological processes are regulated by many means; examples include the control of gene expression, protein modification or interaction with a protein or substrate molecule. Any process that activates or increases the frequency, rate, or extent of smooth muscle cell chemotaxis. A change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a chemical stimulus. Any process that activates or increases the frequency, rate, or extent of leukocyte chemotaxis. Any process that activates or increases the frequency, rate or extent of the directed movement of a motile cell or organism towards a higher concentration in a concentration gradient of a specific chemical. Self-propelled movement of a cell or organism from one location to another. Any process that activates or increases the frequency, rate or extent of the directed movement of a motile cell or organism towards a lower concentration in a concentration gradient of a specific chemical. Any process that modulates the frequency, rate or extent of locomotion of a cell or organism. A change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of an external stimulus. Any process that activates or increases the frequency, rate or extent of the directed movement of a motile cell or organism in response to a specific chemical concentration gradient. The directed movement of a motile cell or organism, or the directed growth of a cell guided by a specific chemical concentration gradient. Movement may be towards a higher concentration (positive chemotaxis) or towards a lower concentration (negative chemotaxis). Any process that modulates the frequency, rate or extent of the directed movement of a motile cell or organism in response to a specific chemical concentration gradient. Any process that modulates the frequency, rate or extent of behavior, the specific actions or reactions of an organism in response to external or internal stimuli. Any process that activates or increases the frequency, rate or extent of behavior, the specific actions or reactions of an organism in response to external or internal stimuli. The specific actions or reactions of an organism in response to external or internal stimuli. Patterned activity of a whole organism in a manner dependent upon some combination of that organism's internal state and external conditions. Any process that activates or increases the frequency, rate or extent of locomotion of a cell or organism.
