user40760: When I first crossed SE biology, I was filled with excitement that I finally found a website, where I could  share my questions with real researchers. I saw the opportunity to improve my rhetorical abilities and finally learn how to form scientific questions.
After three months, I actually did get better with my abilities, but nevertheless that wasn't exactly what did I expect.
Instead, I found lots of people who really don't even try to give me an opportunity to improve my question or give me a hint. They rather downvote  my post without a single comment.
So, I am asking, what is exactly the true purpose of SE biology?
P.S. This is just a point of view from a molecular biology student (first year in the world of science).

user9943: It's quite simple. We are a question and answers site on Biology. We are one of the sites within the larger SE network. We dwarf against sites like StackOverflow in terms of mass. But also within the scientific subclass, we are small compared to Physics and Chemistry.
We mainly thrive because of questions on Genetics, and related disciplines within the Molecular Biology. Questions on Evolution are relatively many too, although stuff like Neuroscience does get some attention too.
The downvoting - the voting system is a core component of the SE network (see here). In a nut shell, and imo, it's all about getting the good posts a good score, and the lesser quality ones low scores. It's mainly a system devoted to rank answers from better to worse. However, question voting is great too, as it brings (bad) questions in the spot light. This is important for moderators and other high-rep users who do not have the time to sift through all the questions, but rather look at the dash board for the odd  posts out.
It seems you are one of many that takes downvotes personally. Don't. It's part of the system. To be blunt, like it, or leave it. 
Now, in fact, in my opinion downvoting is used way too sparsely. It's a strong motivator to improve posts and further, posts with downvotes tend to be removed by the bot, which comes in handy especially for sites still in beta that have to deal with fields of dead and decaying questions that wreck havoc on site stats (Death Valley). As mods can't close-vote without using the mod-hammer, mods tend to downvote a lot. It's not to be mean, it's part of the system.
