The sea and the sky appear blue because of a phenomenon called Rayleigh scattering, where the shorter blue wavelengths of light are scattered more than the other colors by the gases and particles in the Earth's atmosphere. This scattering causes the blue light to be more visible, giving the sky and the sea their blue appearance. As for plants, they appear green because of the pigment chlorophyll, which is used in the process of photosynthesis to capture light energy. Chlorophyll absorbs red and blue light, but reflects green light, giving plants their green color. **

The yellow-green color of the inside of a sea bream is likely due to the presence of bile pigments. Bile is a digestive fluid produced by the liver and stored in the gallbladder, which helps in the breakdown and absorption of fats in the digestive system. The yellow-green coloration indicates the presence of bile in the fish's digestive tract, which is a normal part of its digestive process. **

The North Sea, Baltic Sea, and Mediterranean Sea are all partially enclosed bodies of water, while the open sea refers to the vast expanse of ocean that is not enclosed by land. The North Sea and Baltic Sea are located in northern Europe and are partially enclosed by surrounding countries, while the Mediterranean Sea is connected to the Atlantic Ocean but is largely enclosed by land. The open sea, on the other hand, refers to the unrestricted ocean waters that are not enclosed by land. **

It ultimately depends on personal preference and what one is looking for in a coastal destination.

Both seas have their own unique charm and attractions, so the choice between the two would depend on individual preferences. **

No, the Baltic Sea is not a Wadden Sea. The Wadden Sea is a coastal wetland area in the southeastern part of the North Sea, known for its extensive tidal flats and salt marshes. The Baltic Sea, on the other hand, is a brackish sea located in Northern Europe, bordered by several countries including Sweden, Finland, and Germany. While both bodies of water are important coastal ecosystems, they are distinct in their geographical and ecological characteristics. **

A green screen in gaming is a tool used by content creators to superimpose themselves onto the gameplay footage.
