an invasion of a microorganism from the external environment
The drop in air temperature is a stimulus, as it is an external factor that triggers a response from living organisms or systems. The response to this stimulus could vary depending on the organism, such as shivering in humans or seeking warmth in animals.
Both, for the bug to exhibit an external change (its color), there must first be an internal change that triggers the color change (its color). Thus, the internal change facilitates the external change. The predator is an external factor that causes an internal reaction (maybe it's fear) in the bug, that internal reaction then triggers an external factor which is the change in color. Just a personal opinion.
The initial factor that triggers the process of photosynthesis is sunlight.
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
The catalyst that triggers refers to the event or factor that sets off a particular reaction or process. It is the initial stimulus that initiates a chain of events, often leading to a specific outcome or result.
Because plants were designed too be effient, and they will make minor changes to promote efficiency
Homeostasis is the body's ability to maintain a stable internal environment, such as temperature and pH, through self-regulating mechanisms. Stimulus, on the other hand, is any event or signal in the external environment that triggers a response from an organism to maintain homeostasis. In essence, homeostasis is the state of balance, while stimulus is the external factor that disrupts that balance and prompts a response.
A stimulus is a factor that causes a response in an organism.
A sudden drop in air temperature is a stimulus, as it is an external factor that causes a reaction or response in living organisms. The response to this stimulus could be behaviors like shivering or seeking shelter to maintain body temperature.
Response factor is a multiple factor used in the corrected are area normalisation method to get the correct concentration of the particular component with respect to its response to the detector for example : A solute contains two component A and B of concentration 19% and 81%
When cell signaling causes a response in the nucleus, transcription factors are activated. These transcription factors then enter the nucleus and bind to specific DNA sequences, leading to the regulation of gene expression. This can result in the production of specific proteins that mediate the cellular response to the initial signaling event.
A stressor is a factor or event that causes stress to an individual, leading to a physical or psychological response. Stressors can be internal (such as thoughts or feelings) or external (such as environmental factors or life events).
