A new study said about 65 percent of the online payments last year were done with mobile devices. Along with the rapid growth of the online to offline business, the mobile payment has been further changing people's everyday life. According to findings published by Alipay, the mobile payment is more _ in China's underdeveloped areas. In Tibet, 83.3 percent of the online payments were done with mobile devices in 2015. The region was followed by Guizhou, Gansu, Shanxi and Qinghai. Nearly 80 percent of the mobile payments were done in these regions and provinces. Li Chao, a researcher from iResearch Consulting Group, said that the lack of traditional business was the main reason why people used mobile payment more often.

Everyone knows that chickens lay eggs . Most people know that all the other birds do as well. But have you ever thought about other animals that lay eggs? They include bees, snakes and some sea animals. When a mother lays eggs, many more babies can be born at once, or in a few days, because there is very little development inside the parent. Animals that do not lay eggs often have fewer babies. Animals lay many eggs because other animals may eat the babies. However, even though some of their babies are eaten, they will still have some more to continue their family. Some animals that lay eggs do not take care of their young. Turtles come onto the beach and dig holes. Then they put their eggs in the sand and leave. A turtle mother can lay as many as 150 eggs. When the babies come out of the eggs, they must find their own way to the ocean. They must learn how to live on their own. Many young turtles get eaten by other animals. Most eggs have an outside shell that keeps the growing animal inside safe. The egg shell also keeps the young animal from drying out. After the animal is fully developed, it comes out of the egg.
