habitat temperature
habitat temperature
water in a cell
The correct answer is "water in a cell."
To determine which of the options is an internal stimulus, we need to understand the difference between internal and external stimuli.
Internal stimuli are factors that originate within an organism and affect its physiological processes or behavior. On the other hand, external stimuli come from the environment and elicit a response in an organism.
Let's analyze the given options:
1. Water in a cell: This is an internal stimulus as it refers to the presence or absence of water within the cell, affecting its internal conditions.
2. Amount of daylight: This is an external stimulus as it comes from the environment, specifically the amount of light present.
3. Habitat pollution: This is an external stimulus referring to the presence of pollutants in the environment, not originating within an organism.
4. Habitat temperature: This is an external stimulus as it relates to the temperature of the organism's surrounding environment.
Therefore, the option "water in a cell" is the correct answer as it represents an internal stimulus.
