Responses to stimuli are not examples of adaptation; rather, they are immediate reactions to environmental changes. Adaptation refers to long-term evolutionary changes in a species that enhance survival and reproduction in a specific environment. While responses to stimuli can be crucial for an organism's survival, they occur on a much shorter timescale and do not involve genetic changes.

False. Muscle tissue's primary function is to facilitate movement through contraction, not to receive sensory stimuli and initiate responses. This role is primarily performed by nervous tissue, which is responsible for sensory reception and coordinating responses to stimuli. Muscle tissue works in conjunction with nervous tissue to enable coordinated movement and responses.
Yes, responses to stimuli can be learned through a process called conditioning. For example, in classical conditioning, an organism can learn to associate a neutral stimulus with a biologically significant stimulus, leading to a learned response. In operant conditioning, behavior is shaped through reinforcement or punishment in response to stimuli.

Two examples of external stimuli are pain, and temperature.

An inborn response is a natural, instinctive reaction that an organism exhibits in response to certain stimuli, often crucial for survival. These responses are typically hardwired in an organism's nervous system and do not require prior experience or learning, such as reflex actions. Examples include a baby's grasp reflex or a dog's instinct to bark when threatened. Inborn responses are essential for basic functions and behaviors necessary for an organism's adaptation to its environment.
They are receptors.

Sensitization also called positive adaptation is the type of sensory adaptation in which we become more sensitive to stimuli that are low in magnitude. Desensitization also called negative adaptation is the type of sensory adaptation in which we become less sensitive to constant stimuli.
The ability to respond to similar but distinct stimuli is called stimulus discrimination. It involves discriminating between different stimuli to produce different responses based on their unique attributes, helping an organism differentiate between similar inputs and react accordingly. This process is crucial for learning and adaptation in various environments.
