The bactericide (bacteria-killing) property of honey is named "the inhibition effect". Experiments conducted on honey show that its bactericide properties increase twofold when diluted with water. It is very interesting to note that newly born bees in the colony are nourished with diluted honey by the bees responsible for their supervision - as if they know this feature of the honey.
When a flower has already been visited, the honeybee can understand that another bee has earlier consumed the nectar of that flower, and leave the flower immediately. This way, it saves both time and energy. Well, how does the bee understand, without checking the flower, that the nectar has earlier been consumed? This is made possible because the bees which visited the flower earlier marked it by leaving a drop on it with a special scent. Whenever a new bee looks in on the same flower, it smells the scent and understands that the flower is of no use and so goes on towards another flower. Thus, bees do not waste time on the same flower.
Honeybees are one of science's great mysteries because they have remained unchanged for 20 million years. That is a big blow to the evolutionists.
