comment Very introductory online source of information in evolutionary biology
@Corvus there is a thread for community ads, but I don't have the time right now to design one. Will see if I can do it when I come back from vacation.

comment What is the difference between electrons and energy?
I think there is an interesting question hidden here, but the formulation is throwing us off. Something on the lines of which energy sources does the cell use other than redox reactions of ATP. We could try translating "what does energy do that electrons can't do" as "what do other cellular energy sources do that ATP synthesis/cleaving can't" or something similar.

comment Very introductory online source of information in evolutionary biology
I like this resource very much. Frankly, I'm not knowledgeable about evolution (although it seems many questioners here have an even foggier image than I do) so I'm reading it for myself and finding it valuable. Now that the site has graduated, I think we should make it a community ad.

comment How are 23 chromosomes in human sperm chosen?
Amir, welcome to the site! Your question is very basic, and we have trouble finding out what exactly is unclear to you. Please edit the question to explain which situation you mean exactly (when are they "chosen"? Do you know that human chromosomes are paired? etc.) I will vote to put the question on hold until you have done so, else you will get the wildest guesses as answers, and they won't be very helpful. You can also try reading en.wikipedia.org/wiki/Ploidy, but I admit the language will be hard for somebody who is not a native speaker of English and does not know much biology.

comment How are 23 chromosomes in human sperm chosen?
@chris I think that this question means the OP doesn't know of diploidy and assumes that a more or less random half of the chromosomes present in a normal cell end up in a gamete.

comment How long can a human neuron cell live outside the body in a controlled environment?
You can look into culture protocols. For example this one suggests 7-10 days for culture maturation, then 2 weeks harvest time (scroll down to the last step). While a protocol won't tell you the longest time, it will give you a lower limit for the longest time. This is about nonhuman neurons of course, but there are also human cultures started from stem cells.

comment Is it possible that a set of functionally related proteins in a pathway fulfill different functions?
Hello Costa, and welcome! I don't understand your question. What is supposed to connect to what, what do you mean by property? It's a very broad tem. And maybe you man exhibit, not execute. I know it's not easy if English is not your first language, but people can't answer if they don't know what the question is. You can edit it to add detail, else it's possible that it will be temporarily closed until you explain more.

comment What does x in “Miscanthus × giganteus” name stand for?
@senderle Oh, thanks for catching it. I realized that there must be some misunderstanding after Klara's second comment, but I just didn't make the association with species

Lemongras is also a tough gras, but still used as a spice, sometimes even eaten, cooking.stackexchange.com/questions/53671/…. I don't know why you'd look at spices when you choose biofuel sources though.
