The neurons of your brain specifically. These cells are the functional processing units. There is another neuronal cell type knows as glia which is also important in brain function, and out numbers your 100 billion neurons or so by about 5:1, however they are believed to have less of a functional calculation role and more of a supportive and maintenance role within your brain.
But you as an organism gather information and carry out a response, your brain is what lets you do this.
what spacecraft does not carry humans it gathers data about objects in slace and sends information to Earth
The nerve net of a cnidarian carries sensory information and coordinates movement and responses to stimuli. This decentralized network allows for quick reactions to the environment.
Landsat
A telescope is an instrument that gathers information from a distance by collecting and focusing electromagnetic radiation, such as visible light, to observe celestial objects in space.
Input
Effectors that bring about change receive information from the efferent pathway of a feedback system. This pathway carries signals from the control center to the effector in response to the input received from the afferent pathway. The effector then carries out the necessary responses to maintain homeostasis in the body.
The tongue gathers information through taste buds that can detect different flavors; the nose gathers information through olfactory receptors that can sense various scents in the air; and the skin gathers information through sensory receptors that can detect touch, temperature, and pain.
Mainly telescopes, satellites, etc.
Judgment
it gathers information about space without a crew
Yes, the peripheral nervous system (PNS) is involved in reflex actions. Reflex arcs allow sensory information to be processed in the spinal cord and produce motor responses without involving the brain. The PNS carries the sensory information to the spinal cord and the motor responses back to the muscles or glands.
The nervous system carries messages around the body through electrical and chemical signals. The brain, spinal cord, and peripheral nerves work together to transmit information and coordinate responses to various stimuli.
