La biologie (du grec βίος / bios, « vie » et λόγος / logos, « parole, discours ») est la science du vivant. Son objet est l'étude des organismes vivants, des cellules qui les composent à la physiologie des organismes dans leur ensemble, de l'évolution des espèces aux recherches comportementales, de l'écologie scientifique à la médecine. Les champs couverts par la biologie sont immenses et nombre de domaines qui lui sont liés apparaissent souvent comme des sciences à part entière, étudiant le vivant à toutes ses échelles, des bactéries aux plus grands mammifères.

Blockchain technology is like a digital ledger that keeps track of transactions. Instead of one person controlling it, many computers work together to make sure the information is accurate and safe. Each transaction is put into a block, and these blocks are connected in a chain. It's really hard for anyone to change the information because it's stored in lots of places and protected. This technology is most famous for cryptocurrencies like Bitcoin, but it can also be used for other things like tracking where food comes from or making sure people's identities are secure online.
