Which of the following is NOT one of the four origins of a signal? A) Signals generated by mechanical stimuli. B) Signals transferred from one cell to another adjacent cell. C) Signals from endocrine cells through the bloodstream. D) Signals from immune cells to target pathogens.
Understand the Problem
The question is asking to identify which option does not belong to the list of four origins of a signal, implying that three options correctly describe the origins while one does not fit.
Answer
D) Signals from immune cells to target pathogens.
The final answer is D) Signals from immune cells to target pathogens.
Answer for screen readers
The final answer is D) Signals from immune cells to target pathogens.
More Information
While signals from immune cells to target pathogens are important, they are not typically categorized as one of the main origins of cell signals, which include mechanical stimuli, signals between adjacent cells, and endocrine signals.
Tips
A common mistake might be misinterpreting immune signaling as one of the primary categories of cell signaling origins.
