The following are some common procedures that we should take action of when using a bunsen burner to ensure our safety:
1. Wear safety goggles. Tie up long hair and school ties if needed. This can lower the risk of catching on fire. Put a heatproof mat underneath the Bunsen burner, put a tripod and the beaker of water for heating on top of the burner.
2. Close the air hole. Before we start up the burner, the air hole must be closed or green flame (striking back) may occur
3. light up a match or a lighter. Put it over the chimney.
4. Turn on the gas tap, you should be able to see a yellow flame now. Remove the lighter or match and open the air hole. We should have a blue flame by now.
5. the water should start to heat up. Never touch the hot beaker with bare hands.
6. When the water is heated up to the temperature they wanted to, it's time to close the air hole and turn off the gas tap.
7. If they need to move the hot beaker, use heat protection gloves
These should be the correct procedures that they should follow in order to heat the water safely.

Parental Phenotypes: "Yellow-Smooth", "Yellow-Wrinkled", "Green-Smooth", "Green Wrinkled".
Parental Genotypes: SsGg × SsGg
Parental Gametes: SG, Sg, sG, sg
<span>
Smooth/Green </span>= S-G- = 9
<span>
Winkled/Green </span>= ssG- = 3
Smooth/Yellow = S-gg = 3
Wrinkled/Yellow = ssgg = 1
Ratio would be: 9: 3: 3: 1

<span>The Left-sided Problem of the heart involves the lack of enough supply of oxygen induced blood and the blood which is unable to reach the heart goes to lungs causing breath issues. Another issue with this problem is that left side of the heart pumps blood into the body, so when it fails, less blood will be pumped into the arteries.</span>
