Yes it does, only no air is supplied because it is in amniotic fluid. The lungs and the diaphragm function during fetal development in order to prepare for breathing air after birth. During the time in the uterus, the gas exchange is done by the mother through the umbilical cord and her lungs.
It controls the amount of light that reaches the film.
It allows (forms) a (semi)closed environment for the development of the fetus.
The diaphragm is a muscle that lies beneath the lungs and above the abdomen. It functions by contracting and expanding the lungs and thereby drawing air into the lungs. When the diaphragm relaxes, air is expelled from the lungs.
A zygote is the union of two gametes, prior to the embryonic stage of a developing embryo and fetus.
Deep diaphragm breathing is done by contracting the diaphragm.
It does not because the foetus's blood is oxidized by the mother so there is no need for the foetus to breath. Animals generally take their first breath at birth.
There is no need for it to function. The diaphragm aids with breathing (expanding and contracting the thoracic cavity) but since the mother provides the fetus with oxygen through the placenta (which is connected to the umbilical cord) it doesn't need to "breathe", or expand and contract its lungs.
No, because it gets it's gas exchange done by it's mother.
No
Allows people to breath
to hold the light

No, the diaphragm does not function in a pig fetus. The pig fetus has no need to breathe prior to birth, it receives oxygen through the umbilical cord.
The diaphragm reduces the light from under the stage which can improve the image contrast.

Changing the volume of the chest cavity, and therefore inspiration and expiration.The function of the diaphragm is to inflate and deflate the lungs for gaseous exchange.
