Hay tees métodos pot los cuales se forma las perlas: naturalmente, culturas, o imitación. En la naturaleza, in irritante como un pará o un grand de arena de abre paso entre el manto y la cáscara de in mejillón, una almeja o una ostra. Leugo, como mecanismo de defensa, la criatura marina comienza a secretar una mucosa com minerales conocidos como nácar, el mismo material del que están hechas las conchas. Con el tiempo, la capa de nácar de acumula y después de varios años, las perlas de agua salada tardan más en formarse, una perla está completamente formada. En el método de cultivo, un irritante se implanta quirúrgicamente en la criatura, esto se conoce como el núcleo, la semilla o “madre de perla”. A partir de ahí sufre el mismo proceso que en la naturaleza. No creo que estuvieras preguntando sobre el proceso para hacer perlas de imitación. No hablo Español, así que esto ha sido traducido por el traductor de google si ay algún problema de traducción. Espero que esto ayude.

Gene therapy is able in some cases to introduce a normal copy of the gene and after that, it can restore the function of the protein.
Answer:
lagoon
Explanation:
As the estuary gets more and more sediments, the deposition of them is constantly on the rise, affecting the landscape and forming new geographical features. With the sediments constantly building up, they eventually cut off part of the water from the sea. They will form a closed pool-like feature, filled with water, and surrounded by sediments, cut off from the sea. It will have shallow water, and because the water is stagnant and shallow it will have higher temperature than the other water. This geographical feature is known as lagoon.
