人们还对叶岩保存如此完好百思不得其解，有一种可能性是在化石在形成之时，古生物被迅速掩埋，而当时的环境并不适合细菌分解这些生物的软体部分。
Nobody knows exactly why they were so well preserved. One possibility is that the creatures were buried quickly and in conditions that were hostile to the decomposition of soft body parts by bacteria.

他们的确有更高的乳酸脱氢酶起始水平。这种酶与软组织分解相关，所以这个可能性不能被排除。
They did, indeed, have higher initial levels of lactate dehydrogenase, an enzyme associated with tissue breakdown, so this possibility should not be discounted.
很多生物或者化学题目可以被分解成不同的倾销员题目的版本，而面对这一题目的挑战就是从所有的可能性当中找到最有效的方式。
Many questions of biology and chemistry can be reduced to versions of the travelling salesman problem, where the challenge is to find the most efficient solution among a whole host of possibilities.
这些游离的氧原子能维持它们自己的形式或者和氢原子联合成活性氧(ROS)，ROS能被酶和蛋白分解可逆性影响细胞功能。
These rogue oxygen atoms can remain on their own or combine with hydrogen atoms to form reactive oxygen species (ROS), which wreak havoc with enzymes and proteins and adversely affect cell function.
透明质酸酶是一种DNA酶，分解透明质酸，暂时增加其渗透性，因此容许液体被毛细血管以及淋巴系统再吸收。
Hyaluronidase is a human DNA-derived enzyme that breaks down hyaluronan and temporarily increases its permeability, thereby allowing fluid to be absorbed with the capillary and lymphatic systems.
