Answer:
According to the text, the most likely causes of precocious puberty are exposure to pollutants
, exposure to phthalates and unhealthy weight gain.
Explanation:
The age of onset of puberty has experienced significant variations over the years, mostly related to environmental changes and use of processed products.
Factors associated with precocious puberty are:
- Industrialization produced an increase in environmental pollutants, which has been linked to early puberty.
- Consumption of processed foods —which favour obesity— influences the production of hormones, that can induce early sexual maturation.
- Finally, some chemical additives, such as phthalates, enter the body and resemble the structure of some hormones, inducing a hormonal behavior that promotes alterations, such as an early onset of puberty.
The text also mentions negative consequences for the body when an early onset of puberty occurs.

1.) The process of ejaculation starts with : A testis will produce sperm cells. These sperm cells will travel through the vans deferens. The accessory glands (seminal vesicle and prostate gland) will produce a fluid that will be combined to the sperm cells that will be semen.
2.) The process of menstruation starts with: An ovary will produce an egg cell every month that will travel through the fallopian tube and will go to the endometrium, the lining of the uterus. Since the egg cell is not fertilized, it will not be remained to the lining. Instead, the endometrium that has many blood vessels will shed blood containing the egg cell and that is the menstrual blood.
