Answer;

-Honey contains a considerable amount of sugar (about 82% carbohydrate) and therefore when a microbe (e.g., a fungal spore or bacterium) lands on honey the process of osmosis causes water to be drawn out of the microbe thus blocking its ability to live and proliferate.

Explanation;

Antibiotics are used to kill or inhibit bacteria growth. Honey contains hydrogen peroxide, which may account for some of its antibacterial properties. It also has a high sugar content, which can help stop the growth of certain bacteria.

-Additionally, honey has a low pH level. This works to pull moisture away from bacteria, causing the bacteria to get dehydrated and die off.
