What is the function of a nerve cell in a multicellular organism? (1 point)
Responses
store and distribute oxygen
carry and transmit signals
produce and manage movement
make and move protein
1. Carry and transmit signals
2. They are small because they lack a nucleus.
3. They help the neuron receive messages from the axon of another neuron.
4. A neuron may signal when and where oxygen is needed.
5. Neurons contain DNA, but red blood cells do not.
