Directions Plum stays green because it is a semi-permanent hair dye that does not contain any harsh chemicals like ammonia or peroxide. Instead, it uses a conditioning formula that helps to maintain the color and keep it looking vibrant. This gentle formula allows the color to gradually fade over time, resulting in a green hue that stays true to its original shade. **

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. **

A motor glider is not typically designed for high-sea navigation. While it may have the capability to fly over bodies of water, it is not equipped with the necessary navigation and safety features for extended over-water flights. High-sea navigation requires specialized equipment and training, such as long-range communication systems, life rafts, and emergency locator beacons, which are not typically found in motor gliders. Therefore, it is not recommended to use a motor glider for high-sea navigation. **

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. **

The sea route from Europe to China was discovered by the Portuguese explorer Vasco da Gama in 1498. He successfully sailed around the southern tip of Africa, known as the Cape of Good Hope, and reached the coast of India before continuing on to China. This discovery opened up a direct sea route for trade between Europe and Asia, bypassing the overland Silk Road route. **

The sea route from Hamburg to Hanoi typically involves crossing the Mediterranean Sea, passing through the Suez Canal into the Red Sea, navigating the Indian Ocean, and finally reaching the South China Sea. This route is commonly used for shipping goods between Europe and Southeast Asia, as it offers a direct connection between the two regions. The journey can take several weeks, depending on factors such as weather conditions and port congestion. **
