Embryo research is an emotive issue.(胚胎研究是个让人情绪激动的问题。)
The pause of the development of an embryo has more benefits for preparing it to avoid the harsh times than for competing with its siblings.(暂停胚胎的发育比与其兄弟姐妹竞争更有利于使它做好准备以避免艰难时期的到来。)
The chick embryo proper comes from a very small region resting on the yolk.(小鸡胚胎本身来自于蛋黄上的一个非常小的区域。)
They are now trying toimplant the embryo into a host animal.(他们现在正尝试着将此胚胎植入一个宿主动物中。)
Among other benefits, this allows her to freeze the development of an embryo during times of drought and food shortage until the offspring in the pouch is able to leave.(在其他好处中，这使她能够在干旱和食物短缺时期冻结胚胎的发育，直到育儿袋中的后代有能力自己离开。)
One part will become the placenta the other the embryo.(一部分将变成胎盘，另一部分则变成胚胎。)
Embryo mix-ups at fertility clinics are extremely rare.(胚胎搞混了在生育诊所是极其罕见的。)
This allows her to freeze the development of an embryo during times of drought and food shortage until the offspring in the pouch is able to leave.(这使她能够在干旱和食物短缺时暂缓胚胎的发育，直到育儿袋里的后代能够独立生活。)
Nearly a century ago, biologists found that if they separated an invertebrate animal embryo into two parts at an early stage of its life, it would survive and develop as two normal embryos.(近一个世纪前，生物学家发现，如果他们在无脊椎动物胚胎生命的早期阶段将其分成两部分，它会存活下来并发育成两个正常的胚胎。)
