  1. We do not do your homework for you. Although it might take more effort to do the work on your own, you will profit more from your effort. We will be happy to evaluate your work though.

    Resubmit with your answers.

  3. i know we should be doing our work on our own, but some people like me don't understand or really know health well. maybe next time, tell the student whoever is in need for the answers, maybe give them a helpful website to make them get the answers plus learn new things.

  19. @Not inportant You're obviously cheating because my question is how did you get to this page? You obviously got to this page by looking up the same question so your statement is quite dumb.
