Bacterial culture
Yogurt forms when starter bacteria ferment milk sugar into lactic acid. The resulting acidity changes milk proteins, creating a gel rather than simply thickening milk by evaporation.
Berry
Bananas are botanical berries, while strawberries are aggregate accessory fruits. The distinction depends on how a flower becomes a fruit, not on sweetness, size or the name on a grocery label.
Legume
Peanuts are legumes, in the same plant family as peas and beans, rather than true botanical nuts. Their unusual feature is that the flowers develop above ground but the pods mature below it.
