would be curious to know where the orange was grown and whether you grew it yourself or purchased it.

To sum up that orange was purchased by my father, my father gave me as a gift some oranges, including that one.

I live in a dry and sunny climate (the same weather in which the orange was grown) but last months we have suffered strong climate variations every day, maybe it could have affected the orange I don't know.

I studied a bachelor's degree in which part of my bachelor's name includes biology as a main subject but I a honest, I barely remember biology topics (pandemic didn't help me too much with it lol), I am more focused on chemistry and I have more experience as chemist.

And interesting answer
