Question

A new chemical signal is discovered. It is secreted in low concentrations from keratinocytes in the skin, and it binds to receptors on nearby melanocytes in the skin. Can this chemical signal be classified as a hormone?

Answer 1

Step-by-step explanation:

I would say no because hormones usually travel long distances via blood. This question makes it seem like it is short distance and does not talk about how the secreted entity travels. So my bet is no.
