Baliqlar ko'payish ekologiyasi bilan bog'liq bir-biridan qiziq holatlar mavjud. Shulardan biri Janubiy Amerika suv havzalarida keng tarqalgan xarasisimonlar turkumi vakili Copella arnoldi hisoblanadi.
Ular yosh avlodlarini suvdagi dushmanlardan muhofaza qilish maqsadida tuxumlarini suvdan tashqariga - daraxt barglariga qo'yadi. Bunda erkak va urg'ochi baliqlar suvdan sinxron tarzda sakrab suv yuzasidagi daraxt barglariga yopishib olishadi. Urg'ochi baliq tuxum qo'yadi va o'sha zahoti erkak baliq ularni urug'lantiradi. 3-5 soniyadan keyin har ikki baliq suvga tushadi. Keyinchalik erkak baliq tuxumlar qurib qolmasligi uchun ularga dumi bilan suv sepib turadi.
Ikki-uch kunda tuxumlardan mayda ikralar rivojlanadi va ular suvga tushib o'z rivojlanish hayotini davom ettiradi.

Bitcoin is built on a distributed digital record called a blockchain. As the name implies, blockchain is a linked body of data, made up of units called blocks that contain information about each and every transaction, including date and time, total value, buyer and seller, and a unique identifying code for each exchange. Entries are strung together in chronological order, creating a digital chain of blocks. “Once a block is added to the blockchain, it becomes accessible to anyone who wishes to view it, acting as a public ledger of cryptocurrency transactions,” says Stacey Harris, consultant for Pelicoin, a network of cryptocurrency ATMs. Blockchain is decentralized, which means it’s not controlled by any one organization. “It’s like a Google Doc that anyone can work on,” says Buchi Okoro, CEO and co-founder of African cryptocurrency exchange Quidax. “Nobody owns it, but anyone who has a link can contribute to it. And as different people update it, your copy also gets updated.”
How Does Bitcoin Mining Work?
Bitcoin mining is the process of adding new transactions to the Bitcoin blockchain. It’s a tough job. People who choose to mine Bitcoin use a process called proof of work, deploying computers in a race to solve mathematical puzzles that verify transactions.To entice miners to keep racing to solve the puzzles and support the overall system, the Bitcoin code rewards miners with new Bitcoins. “This is how new coins are created” and new transactions are added to the blockchain, says Okoro.
