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.

Answer:
1/2 IAIB, 1/2 IBIB (es decir, 50% IAIB y 50% IBIB)
Explanation:
El grupo sanguíneo está determinado por un gen que posee tres diferentes variantes o formas alélicas:
alelo A: IA
alelo B: IB
alelo O: IO
Los alelos IA y IB son codominantes entre sí, es decir, un portador de ambos alelos será de grupo sanguíneo IAIB. Por otra parte, tanto el alelo IA como el alelo IB son dominantes del alelo IO recesivo. En este caso, el cruzamiento entre un individuo heterocigota IAIB con un individuo homocigota IBIB dará como resultado una descendencia 1:1 de heterocigotas IAIB y homocigotas IBIB (es decir, 50% IAIB y 50% IBIB), ya que la madre producirá ambos tipos de gametos en proporciones equivalentes (1/2 IA y 1/2 IB), mientras que el padre sólo producirá gametos IB.
