Internal stimulus is a signal that comes from within an organism, such as hunger or pain, that triggers a biological response. It is generated by the organism itself rather than from the external environment. Internal stimuli help to regulate an organism's physiological processes and behaviors.

The internal and external appearance of an organism is called its morphology. This includes its physical characteristics, such as size, shape, color, and overall structure.
homeostasis
The internal environment of an organism can affect gene function by influencing factors such as hormone levels, nutrient availability, and stress response pathways. Changes in these internal conditions can trigger alterations in gene expression, leading to different cellular responses and potentially impacting the overall functioning of the organism.
Internal is inside the organism External is the surroundings and stuff that happens outside the organism
