It is difficult to determine if a duck embryo is alive based solely on a dark spot inside the egg. To confirm viability, it is best to consult with a veterinarian or experienced individual who can perform egg candling to observe the development of the embryo and determine its status.
This is probably a nucleolus, one or more of which are in every nucleus.
The Great Dark Spot on Neptune, similar to Jupiter's Great Red Spot, is a massive storm system on the planet's surface. It is estimated to be about the size of Earth. Therefore, you could fit approximately one Earth inside Neptune's dark spot.

The dark blue spot seen in the center of a cell is typically the nucleus, which contains the cell's genetic material (DNA). In histological staining, the nucleus often appears darker due to the binding of dyes to nucleic acids. This structure is crucial for regulating cell activities and ensuring proper cell function and reproduction.
The nucleolus is the dark colored area inside the nucleus.
