How might a red blood cell work with a neuron to support the function of a multicellular organism? A neuron may produce more red blood cells.

A neuron may signal when and where oxygen is needed.

A red blood cell may produce more neurons.

A red blood cell may carry oxygen to the nucleus of a neuron.

A red blood cell may carry oxygen to the nucleus of a neuron.

Explanation:

The primary function of RBC is to deliver oxygen in the bloods stream to the all the cells,tissues and organs of the body. Neurons are example of such cells .Therefore., the interrelationship is for RBC to supply oxygen to the neurons

The RBC has some adaptive feature which makes this possible. The absence of nucleus is  for enough space to carry oxygen,bi-concave shape for easy penetration of tiny tissues  in the body, and to have large surface area to volume ratio.

Anatomically,the blood vessels usually grow along with the neurons.In most cases they are interwoven .E.g Gial cells and the blood brain barrier. Thus  this gives adequate blond supply to the neurons,by the RBC.

Conclusively,oxygen,nutrients are supplied to the neurons.

the three components of a nucleotide are the nitrogenous base, the phosphate group and the five-carbon sugar.
