What are three physical changes girls go through during adolescence?

Changes in body shape and height, the start of menstruation, and the development of breasts. Hope this helped, have a lovely day.  

As a girl enters adolescence her hips start to widen. Hair starts to grow under the arms and in the genital area. A girls breasts start to develop as they get older. 

1.)dr. natterson- horowitz came to realize that their isn't much of a difference between animals and humans. just like humans, animals can suffer from illnesses and diseases like breast cancer, self injury, anxiety, and many more. she also discovered how they even treated and performed surgical procedures on animals just as if the animal it self were human. the los angeles zoo called dr. natterson- horowitz because they knew that she was a doctor and that  she would be able to recognize what was wrong with the gorilla. they knew that humans and gorillas were similar, so instead of calling another veterinarian, they called a doctor.
