Flour is the ingredient on which most baked products are based. Flour is made up of starch, protein, sugar and minerals. The protein content decides what the end use of the flour will be. Milk is used in baked products to improve texture and mouthfeel.
Precocious puberty is when a child begins puberty much earlier than the 'standard' age. For girls, this is generally as early as 7-8 years old, as most girls will not start menstruating until 12-13ish. They could then, in theory, become pregnant at that age if sexually active or raped.
Teenage pregnancy is a situation which involves female adolescents. A teenage female can be pregnant as early as age twelve or thirteen, although it is usually fourteen and older. The fact that teenagers become pregnant is related to many factors.
