  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.

  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.

  37. I agree with baby cakes, but I disagree with one thing they said ( I said they because Idk if its boy or girl). So when they said if you are not a cheater, then don't come back/get back on, some people look up questions similar to their own to check their answers, even if you could ask an adult that you live with to help check your answers, yeah you could do that, but most of the time they are busy and I know how that is because I have a parent that is always busy and already has a lot on their plate, so when I know I can't ask to get my answers checked, I do one thing any person could do, do it on my own. Also at the same time, you could check your answers by going back in your lesson and look for the key sentences that relate to the questions on the quiz.

  41. @Baby Cakes, most people came here to check their answers. Including me. Also, teachers don't know about this site and if they did they would have blocked it for all of the students. I came here with my answers and I wanted to see how well I would have done and what I got wrong, and why. I used to put up these questions or quizzes here hoping people would respond to me and I cheated but I actually started to read through my lessons because I was failing and got help from my teachers and now I'm getting B's. Not D's and F's. So I'm %100 positive the person who posted this and people who are just giving away the answers could do the same. Here are the explanations for the answers (Write it down in your notes maybe):

    1-B,C: The respiratory system does two very important things: it brings oxygen into our bodies, which we need for our cells to live and function properly; and it helps us get rid of carbon dioxide, which is a waste product of cellular function.

    2-D: The diaphragm is a thin skeletal muscle that sits at the base of the chest and separates the abdomen from the chest. It contracts and flattens when you inhale. This creates a vacuum effect that pulls air into the lungs. When you exhale, the diaphragm relaxes and the air is pushed out of lungs.

    3-A: Through the very thin walls of the alveoli, oxygen from the air passes to the surrounding capillaries (blood vessels). A red blood cell protein called hemoglobin helps move oxygen from the air sacs to the blood. At the same time, carbon dioxide moves from the capillaries into the air sacs.

    4-C: The main components in cigarettes are chemicals known as tar and nicotine. Regular cigarette smoking will eventually cause tar stains and residual buildup on your teeth, which is why many cigarette smokers have yellow-stained teeth.

    5-D: A smoker's level of CO varies according to the time of day, the number of tobacco products smoked and how the smoke is inhaled. ... Carbon Monoxide enters the blood from the lungs and combines with hemoglobin, blocking the blood's ability to carry oxygen to body cells.

    Hopefully this helped :) <3

  51. @notinportant ok, so stop telling us we are cheating, i guess because we go on a site for help, it means we are cheating, well i guess your cheating too! And it isnt are fault that some people are nice enough, and waste their time, to type in all the answers! And apparently you clearly need help with your spelling, so i guess on this site, go and "cheat" by learning how to spell! And yes ik, this was all in like 2015, but it gets on my nerves when ppl do this! anyways thank you!
