Microtubule – serves as a framework of the cell –cytoskeleton.<span>

Nucleus – the control center of each cell. It regulates, monitors and organizes the whole cell<span>
Since the pictures isn't given I can assume that it can be the microtubule, the microtubule is responsible for maintaing the shape and structure of the overall cell. It maintains homeostasis by permanently aiding the framework of the overall cell.
If it is the nucleus, the control center of a cell. It does a lot of functions in the cell, it helps maintain homeostasis by sending commands that the organelles do, supply energy, excrete or digest waste, regulate the movement of objects and cellular respiration, even cell division. It sustains the cell to be functional and proactive at the same time reactive to situations that is likely to occur.

Answer:
Water (H2O)
Explanation:
Light reactions of photosynthesis release oxygen as a by-product. In the presence of sunlight, photolysis of water molecules occurs. Splitting of two water molecules obtains four electrons, four protons, and molecular oxygen. The oxygen-evolving complex, also called the water-splitting complex is associated with photosystem II (PS II). Splitting of water occurs in the oxygen evolving complex and the released electrons are passed one at a time to the reaction center of PS II. Therefore, a water molecule serves as a source of oxygen released during photosynthesis.

One major lab accident was of fire where gases were exposed to heat.
<u>Explanation:</u>
Accidents that occur in the laboratory which lead to some mishappening are known as the lab accidents. The reasons for such accidents may be many like fire, chemical spills, personal injuries and so on. To avoid all this, there should be proper check and focus while working in the lab.
One of the major lab accidents was of the fire when gas was exposed to heat. The chemical involved in this accident was the use of methane. The type of personal protective equipment worn at the time of accident was protective eye-wear and the lab coat and the lab gloves. To avoid such kind of accidents, people in lab should be very careful and it should be made sure that there are proper equipment in case of any mishap.
