Why is the ability to respond to stimuli critical?

Answer & explanation:

The stimuli are captured by the sensory system receptors through electrical impulses, being translated by the central nervous system (CNS) into sensations and generating responses.

Thanks to the stimuli, we can react to the cold or heat on our skin, see the things and colors around us, taste and smell foods and hear and interpret sounds.

The sensory system, responding to stimuli, maintains the functioning of the five senses, in addition to controlling the immune system, the organs and the functioning of the other systems of our body.

space exploration has led to the development and technological improvement of many everyday items. (if this answer is wrong i will find the right answer) : )

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.
