One way is to dip wires from a battery into water. Oxygen bubbles appear at the positive wire (and hydrogen at the negative). This method is called electrolysis.

Red blood cells do not have a Golgi apparatus. They lose their nucleus and other organelles during maturation, including the Golgi apparatus, to make space for more hemoglobin, which allows them to efficiently carry oxygen.
fill with water
The instrument used in the laboratory to split water into hydrogen and oxygen is called an electrolyzer. It uses an electric current to drive the splitting of water molecules into hydrogen gas at the cathode and oxygen gas at the anode.

The least count of a chemical dissolved oxygen reflux apparatus is usually determined by the precision of the measuring instrument used to detect changes in the dissolved oxygen levels in the apparatus. This can vary depending on the specific equipment being utilized, but generally, it is around 0.01 mg/L or lower.
When the Hoffman apparatus is used, the decomposition of water produces hydrogen gas at the cathode and oxygen gas at the anode. This process occurs as an electrolysis reaction where an electric current is passed through water to split it into its constituent elements.
An aqualung is a piece of equipment consisting of an oxygen tank and breathing apparatus used by divers to allow them to breathe underwater at depth.
apparatus
The oxygen tank, or portable breathing apparatus, was invented by Emil von Behring in 1904. It was used to provide medical oxygen therapy to patients with respiratory conditions or during surgeries.
To make oxygen at home, you can use an electrolysis process by passing an electric current through water to separate it into oxygen and hydrogen gas. This can be done using a simple electrolysis kit or apparatus. It is important to follow safety precautions when working with electricity and gases.
vicats apparatus is used for initial setting time of cement.
yes glucose is used to make.
The gas in the apparatus before generating oxygen was likely atmospheric air, which contains a mixture of gases including nitrogen, oxygen, argon, carbon dioxide, and others.
