A diagram of the human central nervous system is shown below. Which of the following best describes the function of the human nervous system? A. The nervous system breaks down large food molecules into smaller nutrients so that they can be transported around the body. B. The nervous system transports oxygen and nutrients to the cells of the human body through a system of nerve cells. C. The nervous system gathers, interprets, and responds to information about the body's internal and external environment. D. The nervous system removes waste products from the human body through the excretion of sweat
i dont know what it is
C because the nervous system respones to all functions of the human body.
thank you got it right
are you entering these online?
idc if you do just asking
When a hot surface is touched, receptors in the hand send a signal to the nervous system. The nervous system then sends a signal to the muscles in the arm to contract and move the hand from the hot surface. Which of these best describes this example? A. A behavioral response triggered by an internal stimulus does not require communication between cells. B. A behavioral response requires coordination and communication between different parts of the body. C. An internal stimulus does not require communication between different parts of the body. D. Cells in the body work independently of each other and have no need to coordinate or communicate.
B. A behavioral response requires coordination and communication between different parts of the body.
The ______ is the control center of the nervous system. It sends and receives signals to and from the entire body. A. spine B. heart C. brain D. stomach
A as shown in the model
post another question
u sure its a
Its between A and C
yea i put A
nvm its the brain because it controls the nerves sorry my bad...
was a right.
it was C I believe
yea it was c but i put a
The brain controls what we think and feel, how we learn and remember, and the way we move and talk. ... The rest of the nervous system is like a network that relays messages back and forth from the brain to different parts of the body. It does this via the spinal cord, which runs from the brain down through the back.
ye what they said
Which statement best explains why sensors (or senses) are necessary to produce a change in behavior? A. Stimuli must be responded to in order to be sensed. B. Organisms cannot respond to stimuli without a central nervous system. C. Stimuli must be sensed in order to produce a response. D. Organisms cannot sense stimuli without a central nervous system.
Stimuli must be sensed in order to produce a response.
yes im sure
it was C
Jorge wants to move toward light. Once Jorge's eyes detect light, how do his eye cells communicate with his muscle cells so that he can walk toward the light? A. The eye cells release hormones that signal the muscle cells to contract and relax. B. The eye cells transmit nerve impulses to the muscle cells in Jorge's legs. C. The eye cells send a chemical signal to the brain, which interprets the signal and then transmits it to Jorge's legs. D. The eye cells transmit nerve impulses to the brain, which translates the signal and transmits nerve impulses to the muscles. Reset Submit
cool im tired sorry
The eye cells transmit nerve impulses to the brain, which translates the signal and transmits nerve impulses to the muscles.
the brain is what controls the muscles boom
Sensory cells in the human eye can detect changes in light. The information obtained from these sensory cells is transmitted to the brain through neurons, and the brain determines the correct behavioral response. For example, if the intensity of light being detected by a person's eye rapidly increases, the nervous system might transmit information to the eye that causes the eyelid to close and block out the light. This is an example of a behavioral response that A. must be completed by a single cell. B. is not influenced by an organism's environment. C. requires communication between several individual organisms. D. requires communication between cells and an organ system. Reset Submit
The eye cells receive light signal. Transduction of light to a neural signal (nerve impulse) Transmission of nerve impulses to the brain via optic nerve (afferent nerve) Brain translates the signal Nerve impulses is transmitted from the brain to the muscles via efferent nerves.
im just saying who it happens.
