Any process that modulates the frequency, rate or extent 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.

positive regulation of response to 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.

negative regulation of response to stimulus

Any process that stops, prevents or reduces the rate, frequency or extent 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.

The increase in size or mass of an entire organism, a part of an organism or a cell, where the increase in size or mass has the specific outcome of the progression of the organism over time from one condition to another.

Any process that stops, prevents or reduces the rate, frequency 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 rate, frequency or extent of cellular processes, those that are carried out at the cellular level, but are not necessarily restricted to a single cell. For example, cell communication occurs among more than one cell, but occurs at the cellular level.

Any process that stops, prevents or reduces the rate, frequency or extent of cellular processes, those that are carried out at the cellular level, but are not necessarily restricted to a single cell. For example, cell communication occurs among more than one cell, but occurs at the cellular level.

Any process that activates or increases the rate, frequency or extent of the viral life cycle, the set of processes by which a virus reproduces and spreads among hosts.
