hundreds of (numerous) chemical reactions taking place in each (molecular) cell (in all individual cells). 四十億年前,地球上沒有生物;是化學(xué)改變了地球的表面,而不是生物。在那個(gè)曠遠(yuǎn)的時(shí)代,礦物、海洋、大氣是第一個(gè)生物體賴以成形的僅有物質(zhì)。 曠遠(yuǎn)的時(shí)代 remote past, distant epoch 賴以 depend on (upon), rely upon There was no life four billion years ago。 It was chemical (reaction) which (or that) changed the surface of the earth, but not biological material. In that remote past, minerals, ocean, and atmosphere were the only materials upon which the formation (or creation) of the first life (or anism) depended. 因此,化學(xué)反應(yīng)必定是生命起源的第一步。一系列的化學(xué)變化,將空氣、水、礦物中的簡單成分,組裝成一群具有複製能力的含碳分子。 Therefore, chemical reactions must have been the first step in the origin of life (in the processes of forming life). Through a series of chemical reactions, the simple molecules in the air, water and minerals, could be bined to form a group of selfreproducible carbonbearing (carbonaceous) molecules. 謝謝觀看 /歡迎下載 BY FAITH I MEAN A VISION OF GOOD ONE CHERISHES AND THE ENTHUSIASM THAT PUSHES ONE TO SEEK ITS FULFILLMENT REGARDLESS OF OBSTACLES.
