user-1: I am really  against this policy of not  answering homework questions. .StackE is supposed to be a community of helpers ans not those who arrogantly delete questions.  While preparing for our exams we dont have so much time to write each and every detail....why cant the community just provide the answer without counter agitation! ! At the time of exams we are exhausted and the community keeps firing questions on us. This is a hoŕrible policy.  People  preparing for their exams should be given their answers. Can anything be done for us ?????

user3553: We do answer homework questions.
Nobody has mentioned this thus far. We actually do answer homework questions, which is somewhat unusual for stack exchange.
I am generally tolerant to homework questions; there have been interesting & impactful homework questions in the past and there will be plenty more to come. These range from zoology, to bioinformatics, to biostatistics.

Who are humans' closest relatives, after primates?
What is the optimal frame size for protein secondary structure prediction methods?
Deciding between chi-square and t-test.

Why many homework questions aren't being answered.
Not many homework questions stay open for very long here. Incidentally the most common close reason by a mile is homework. This is primarily because of relatively new users posting questions that appear to be straight form an assignment without any attempt at an answer. In the future, use these steps as a rule of thumb if you need help with a part of your educational course:

Have I read around? In your question, post what you have read.
Have I asked someone I know with expertise like a teacher or a colleague? Probably quicker, and more able to pinpoint exactly what you don't understand. Post what you learned from that discussion.
Have I attempted a reasonable answer? Post this in your question too.
Have I added the homework tag? This transparency is a sign of good faith & will encourage answers that explain things with less jargon.

If this question has arisen because of some educational course content, an additional step is to ask if it would count as cheating to ask for help.


Note that this does not guarantee your question will stay open. If the community feels that it is too trivial, off-topic, unclear, or if it appears like you're attempting to cheat then the question will likely be closed.
Why your questions aren't being answered.
I think previous answers sum it up and go into detail more than I would want to. Your questions are being challenged and closed because you have not shown a good-faith attempt at an answer. What is the advantage in helping you if you aren't willing to go through the steps above?

People preparing for their exams should be given their answers.

This type of self entitlement completely undermines the legitimacy from the "we should answer homework" argument. It incidentally damages the communities perspective of answering useful homework questions.
You've attracted a lot of negative votes here. This is only partially because of what you're asking. The way you have asked your question involved you making some offensive and unfounded assumptions about members of this community: 

We're not as busy as you during your exams.

Assume that the answerer will be more busy than you. The prominent users of this site include world leading researchers, academics, industrial experts, and other knowledgable experts that have lots of other more important things to get on with.

Your time is more valuable than ours.

By virtue that you are asking a question, the answerer's time is more valuable.

You deserve an answer regardless of how clear the question is.

It's up to you to make your question stick to the guidelines and be up to the community standards. Homework questions suffer from the xy question problem because the asker has no idea about exactly what they don't understand. It's important that an answerer knows exactly what the asker is asking.



user19521: Your misinterpretation of biology.se 
First of all, what I feel like that you are misunderstanding here, is that you think it is our duty to be on biology.se, and that we are probably even getting paid for it. This is incorrect. 
What biology.se is about 
The active people on here are here to have an exchange about/on biology, and if possible help people. However, about the helping part, there are very clear guidelines, which you should read before posting anything. 
What to do for the future?

Read the how to ask a question section from the help center 
Take the tour, there is a reason why it exists  

There you will come across this: 

Have you thoroughly searched for an answer before asking your question? Sharing your research helps everyone. Tell us what you found and why it didn’t meet your needs. This demonstrates that you’ve taken the time to try to help yourself, it saves us from reiterating obvious answers, and above all, it helps you get a more specific and relevant answer!

In your case, some of the questions you posed can really be answered by some rather quick google searches. 
This isn't a let me post my question without having done any research before and expecting the community to do my work forum. 
From the help center: 

What should I do before I ask the question?
Research it yourself - even if you try and can't find the answer or understand the concept you need you can then include what you have found out yourself in the question.
  Search the site to see if something similar has been asked before.
How should I ask my question?
  Give full details of the problem.
  Include details of how you have attempted to form a solution. We will not do your homework assignments for you but we will point you in the right direction if you have made the effort to research the topic first.
  Use logical and clear formatting as this will increase your chances of getting an answer. For example, include tasks from your assignment in blockquotes.

In your case, you really have to work on the formatting of some of your questions. Examples: (1,2,3) (note that some of the questions have been edited by other users) 
NB: as suggested by @remi.b as a comment on your latest question "please don't try to make us feel pity for you"

user948: Jordi made some good points, I'd like to add a few.

While preparing for our exams we dont have so much time to write each and every detail....why cant the community just provide the answer without counter agitation! [...] People preparing for their exams should be given their answers.

I'd like to point you to an excellent meta post on Programmers.SE. While it uses programming for the examples, the general form is applicable for any student with homework questions. A few key points:


Don't expect an answer in any given time frame. The urgency of your question is not something we are concerned with.


I am reminded of a poster seen in more than one colleague's cubicle: "A lack of preparation on your part is no reason for an emergency on my part." Questions get answered as they get answered - there is no time frame requirement. Some may get answered right away, others take hours, or days, or weeks before someone has an interest in it. Some never get answered. Adding things to your post like "HELP PLZ!!!!!! CAN U ANSWER THIS SOON, MY EXAM IS 2NITE!!!1!1" will actively discourage people from answering, as will txt-speak, which many of us abhor. This is a professional environment, please act like one.


Describe the problem you are having, what your understanding of the problem is and where you are confused. For a question from a student, the best questions are often the ones that are asking how to take a single step in understanding rather than trying to leap all the way to the solution.


As I say to many people, I strongly suggest you take the tour and carefully read through the help center to learn more about the site, including what is on-topic and what is not, and how to ask a good question. Knowing what is on- and off-topic for the site, as well as the other reasons why questions get closed (too broad, opinion-based, unclear questions, personal medical advice, posted on wrong site, etc.) will go a long way towards writing good, answerable questions.
Please remember that the primary purpose of Stack Exchange is not to answer questions for a particular user. The goal is to build a repository of good, specific questions that have well-researched, specific answers so that others can find and be helped by them in the future. The focus is not on you at all in the long run. Therefore, enduring, well-asked questions is what we are looking for, not question 7 on your ecology test.


Copy and paste takes no skill. It cheats you out of the education you are paying to get.


You are taking a particular class to learn about some topic, understand how it's used, and apply your knowledge to real-life situations. This requires puzzling through the steps until you intuitively grasp the concept(s) at hand. As a professional cell and molecular biologist, I almost never think about the Krebs cycle in my everyday work, or how many molecules of Ac-CoA are produced from an 18-C  saturated fatty acid. However, I understand at a fundamental level the reason for the Krebs cycle (also known as the citric acid or TCA cycle) and what it does, and so can apply that knowledge toward generating in my mind a model of how the cell metabolizes nutrients, which may be important for understanding how negative regulation in the immune system works on a molecular level. 
If you don't have a good, solid understanding of how these systems work, but you did manage to copy and paste a good answer from Bio.SE into your final essay so you pass the class, you gain nothing. The money, time, and effort expended on that class were worthless, because you didn't learn anything except how to copy and paste from the internet because some poor sap on a website felt bad for you and gave you a clear, detailed answer to your poorly-researched, misunderstood question.
Why should we care what you do with the answer? Because you are part of the next generation of students, or post-docs, or employees working with me in my lab. A scientist with a full, solid background in basic science and training in how to apply it has many of the tools necessary to be an innovative, thoughtful investigator making new discoveries on his/her own. If you cheated and copy-pasted your way through school, you're not going to know how to perform effectively in the lab, requiring extra training, guidance, and supervision, and possibly never contributing on any real level to the work of the lab. You may never even get in the door in the first place, because you won't be able to answer basic interview questions.
So, do your homework! It's perfectly fine to have questions about things - you just need someone to use a different analogy to explain a concept, or you just can't make the logical leap from A to B. But, as all good scientists know, you need to put in the effort to answer those questions, and be a good communicator in regards to what you're looking for and why. There are plenty of excellent homework questions on this site. However, many are not so good, ranging from lousy to completely awful, and we need to maintain the quality of the site for future visitors. Don't be offended if someone asks you to explain something further, or describe your research more, or narrow your question to meet our criteria. We are NOT Yahoo Answers, with no quality filters whatsoever, and page after page filled with nonsensical tripe. We're a different kind of website, and our processes have been put in place for very good reasons. We welcome you to become a good contributor to the site, but we still won't do your homework for you.
