Question 8 of 10
Eating a lot of carrots makes a person able to see in the dark.
Why, in question 7: Well-stored honey can last for many years without spoiling.
That's true. When tightly sealed, honey can last for many years without spoiling. It has little water, is acidic, and contains substances that make it hard for microbes to grow. Over time, it may crystallize, but that does not mean it has spoiled.
How bees make honey
Bees collect nectar from flowers, which is very watery, and transform it inside the hive. Enzymes break down the sugars, and the beating of their wings helps evaporate the water until the honey becomes thick.
To produce one kilo of honey, the bees of a hive visit millions of flowers.
Crystallization happens because honey has more dissolved sugar than water can hold. Heating the jar in a water bath, over low heat, makes the honey liquid again.
Because of spores of a bacterium that may be present in honey, pediatricians recommend not giving honey to babies under 1 year old.
Humans have used honey for thousands of years. Paintings in a cave in Spain, about 8,000 years old, already show a person collecting honey from a wild beehive.
