One long, single molecule of double stranded, helical, supercoiled DNA. In most bacteria, the two ends of the double-stranded DNA covalently bond together to form both a physical and genetic circle
The laboratory is full of chemicals and other hazardous substances. So, it is very important to keep all the safety precautions before entering in the laboratory to avoid any mis-happening.
Here are some precautions, which one should take before entering lab:
- Before entering the laboratory one must wear all the safety equipment including gloves, goggles, apron, and others.
- Make sure you are not wearing any inflammable thing and you are fully covered, as in some laboratory, harmful radiation are also present.
- Make sure your hair are tied in properly and the shoes are covered.

Answer:
The leaf discs only float in bicarbonate solution and in the light environment.
Explanation:
The bicarbonate dissolves in water to produce a source of inorganic CO2 in the reaction:
NaHCO3 + H2O → H2CO3 + OH- + Na+
Then, the HCO3- undergoes fixation through several complex steps in order to form a carbohydrate or sugar. These store the converted solar energy in their bonds as chemical energy to be used in metabolism.
Photosynthesis is a chemical process, essential to plant and other primary producers producing energy. Energy in the form of glucose molecules is derived from solar or light energy, water, and inorganic carbon dioxide, while it releases oxygen (from the light reaction). The leaf discs float as O2 gas is produced, making them buoyant.
6CO2 + 6H20 + (energy) → C6H12O6 + 6O2
Carbon dioxide + water + energy= glucose + oxygen
