That isn't true, it is effected by environmental factors, including many chemicals. However, it is a natural process.

The main organ affected is the ovaries. Also the breasts become bigger in size.

The entire body is affected because puberty involves the release of many hormones. However, in females the body is greatly affected in the pubic area, the breasts, the underarms, and the curves of the waist. In men, puberty is noticed in facial hair, underarm hair, pubic area, genitals, and a deepening of voice.
It depends upon genetics and environmental factors but anywhere from 10-16 is average. Girls usually start puberty before boys do.
I don't believe that we have a sufficient understanding of neural physiology to provide you with an answer other than puberty.
Yes, durng puberty, there is a lot of change done to the vocal chords. So the voice changes.

Absolutely not. Puberty is a natural stage of development. Choosing, right or wrong, is a learned or affected behavior. I know of dozens if not hundreds of people decades past puberty who still make wrong choices, and puberty is not a choice; it is an immutable, inescapable force.
it's basically equal. guys and girls both have to adapt to changing bodies. everyone goes through puberty. guys and girls just adapt differently. (girls are affected waay more than guys though)
Similar for individuals in a particular age group. Include menopause or puberty, retirement or beginning formal education.
