Answer 1

Hello, Jomez. Welcome to OpenStudy. First of all , let me introduce you to this site. This site "OpenStudy" supports educational information, questions, problems, doubts and focused more on discussion rather than direct answers that are mostly given on other sites, that's why it is different from others.
OpenStudy has been divided into several groups to make everything easy. The group at present, where you have posted the question is "Biology" and so, only Biology questions are preferred. Please try to post right questions in right groups.

To find the suitable groups , go to the "find more subjects" and search for the needed subject category and ask your doubt there. It is easy. As you're a beginner in this site:
