Yes, they can.

The threshold stimulus is the stimulus required to create an action potential. So any stimulus under this level will not cause muscle contraction, while a stimulus above this level will cause the muscle to contract. The higher the stimulus the more muscle fibers are recruited, and thus the higher the response.
an absolute threshold
Each of the individual muscle fibers in the muscle are contracted when the maximal stimulus is achieved. Dr. H.
Signal detection theory assumes that top-down processing can influence a person's absolute threshold for a particular stimulus. This theory suggests that factors such as individual differences in attention and expectation can impact an individual's ability to detect a stimulus in a noisy environment.
Automatic involuntary responses vary depending on the stimulus and the system involved. You need to be more specific.
No. No. NO.
Carbon dioxide is the most important stimulus to breathe.
An animal's immediate automatic response to an external stimulus will vary depending on the circumstance. When the external environment is stimulated there is a response that is triggered.
the expression S-R is used to symbolize the deterministic relationship of stimulation "S" standing for stimulus, and "R" standing for response, thus meaning that a stimulus arouses a response or a response is aroused by a stimulus. most of the time a third element is added to the formula to make it more comprehensive "O". that is the organism or individual differences.
behviour refers to the response made by an individual. The response may be the result of influence of external factors. The external factor is termed as stimulus and the acton taken by the individual is known a srespose
