List the steps of how tissues
help your hand move when
you touch a hot stove.

in your hand send a message to
the spinal cord. A reflex takes place
when nerves in the spinal cord send
signals to muscles in your hand that
cause you to move it off the stove. Then,
the nerves send a message up the spinal
cord, where the brain receives it.

organism the ability to
respond to stimuli in the
environment
 Nerve
tissue

 Connective
 Muscle
 Nerve
What do organs have in
common?
 They
