Answer:
In the group of terms, the exception to abiotic factors is bacteria (option b).
Explanation:
Abiotic factors correspond to the elements of an ecosystem that are not considered alive, such as soil, wind, temperature, pH, among others.
All living beings in an ecosystem are biotic elements, including microorganisms such as bacteria. The dynamics of living beings influence the ecosystem, just as abiotic factors influence both the biotic elements and the development of the ecosystem.
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.

The original question has a set of choices. This is within the context of cell division. The choices are:
A. A cell in G1 of interphase and a cell in G2 of interphase
B. A cell in G1 of interphase and a cell immediately after the completion of meiosis II
C. A cell in G1 of interphase and a cell in metaphase II of meiosis
D. A cell in G2 of interphase and a cell in metaphase II of meiosis
<span>E. None of the above.
</span>
The correct answer is C. A cell in G1 is diploid and the cell in meiosis II is haploid but the amount of DNA still equivalent as each chromosome in the haploid cell consists of two chromatids. G2 cells already had been through the S phase therefore the genetic material is already doubled. A cell immediately after meiosis II has half the genetic material.
