Answer: b. it takes time for signals to travel all the way to the brain.
Reflex reaction is the instantaneous reaction of the body to the applied external stimuli. This mechanism is present in the body to make it possible to quickly react to situations without putting much effort into thinking and processing the nature of the stimuli. The reflex arc does not include the brain. This is because the brain has to receive signal from the sensory organs through sensory neurons, process it, and send a signal through the motor neuron to the muscles to generate a response. The whole process is time taking and lowers the reaction time of the organism, which can be dangerous in certain situations.

Answer:
Water, carbon dioxide, and oxygen are among the few simple molecules that can cross the cell membrane by diffusion (or a type of diffusion known as osmosis ).
