The large crater, is the air sack, used when the fertile chick develops lungs and needs air, but the air is limited, so the chick breaks out. The yolk (the yellow thing inside the white) is the newly hatched chicks food source, and the white would have been the embryo. Therefore, the enzymes have nothing to do with it.
The large holes on the moon are called craters. They are formed by the impact of meteoroids, asteroids, and comets colliding with the surface of the moon.
The theory is that these are impact craters of meteors.
No, not all craters on the moon are impact craters. Some craters are created through volcanic activity. Volcanic craters are formed when magma rises to the surface and erupts, creating a depression.

You're probably talking about craters. Craters are made when an Asteroid hits the moon.
Most craters are caused by meteorites crashing to the planet. However, some volcanoes when formed, look like craters.

We can see the craters of the moon clearly from Earth because the moon has no atmosphere to erode them, so they remain preserved. When the sun shines on the moon's surface at an angle, it creates long shadows that make the craters stand out more prominently, enhancing their visibility from Earth.
