YOU SAID:

An egg is the organic vessel containing the zygote in which an animal embryo develops until it can survive on its own; at which point the animal hatches. An egg results from fertilization of an ovum. Most arthropods, vertebrates, and mollusks lay eggs, although some, such as scorpions and most mammals, do not.

INTO JAPANESE

卵はそれは独自に生き残ることができるまで、動物の胚が成長する受精卵を含む有機性容器です。その時点で動物がハッチングされます。卵は卵子の受精に起因します。ほとんどの節足動物、脊椎動物と軟体動物は、サソリなどほとんどの哺乳類、一部はしないが、卵を産みます。
