Late in the third semester
The respiratory usually develops at 12 weeks so i would definitely say breathing starts in this period.
Bone remodeling begins in embryonic development
A gastrula is an embryo in the cell organization of development, when the three germ layers form. This is called gastrulation, and the three layers are the endoderm, mesoderm, and ectoderm. A neurula is an embryo at the stage of development when the nervous system begins developing, called neurulation. Neurulation happens after gastrulation.
Zygote (1 cell)8 cells stagemorulablastocyst (with hollow center called a bastocoel)gastrlation (forms three layers: endoderm. ectoderm and anchentron)pluteusimplantationneural development begins.
Primary succession is when development of an area that has not had a community begins. Secondary succession is when a community starts to rebuild itself after a disturbance(Like a hurricane or tornado). Hope this helps :D
metaphase
Depends on when you consider it a child. First it's a Zygote, a fertilized egg, and then a blastocyst. Medically it's not a child until it's born. But if we start with embryo you can read all about it in the link below. Someone wrote blood starts pumping and arms starts to develop but that is weeks later. Blood pumps through the body. or Rhythmic breathing movements

Development begins before birth and ends generally ends at the age of twenty-five.
development begins earlier.
Diaphragm
diaphragm (a muscle used when breathing)
it begins when you breath through your nose and into your lungs.
adulthood
No, that is false.
an idea for a product is formulated and development of the product begins. During this stage sales are zero, consumer research begins, and promotion consists of public relations
