哺乳动物的

Scientists in Australia estimated, for the first time, the bite force of a wide range of mammalian carnivores.

通过研究动物的头骨化石，科学家在已经灭绝的食肉哺乳动物中也得到了相似的结论。

Like the 5′UTRs of mammalian picornaviruses, the 5′UTR of EoPV was rich in A/T, and had many AUG and small cistrons positioned upstream from the authentic initiation codon.

克隆测序后，对其5′端非编码区的核苷酸序列进行分析，发现具有哺乳动物小RNA病毒的5′端非编码区的一些特征：A/T含量丰富、起始密码子上游AUG和小顺反子多。

Our results demonstrate that intestinal bacterial commensals and the immune system communicate through an innate detection system to generate adaptive lymphoid tissues and maintain intestinal homeostasis.

哺乳动物中这一由微生物诱导的组织形成方式的罕见事例说明，细菌与宿主之间的一种建设性互动何以能够帮助实现高效消化和保护宿主不受小肠病原体侵害。

In mammalian cells, RNAi can be triggered by 21-25 nucleotide duplexes of small interfering RNA.

在哺乳动物细胞里，RNAi可以由21－25个核苷酸长度的小干扰RNA触发，在后基因组时代的基因功能研究和药物开发中具有广阔的应用前景。

In mammalian cells, RNAi can be triggered by 21-25 nucleotide duplexes of small interfering RNA. In the postgenome era, RNAi has broad application prospect in probing gene function and drug research.

在哺乳动物细胞里，RNAi可以由21－25个核苷酸长度的小干扰RNA触发，在后基因组时代的基因功能研究和药物开发中具有广阔的应用前景。

The regulation of cell cycle in eukaryote is an important research field in cell biology.

细胞周期调控研究已成为当前生物学领域的一大热门课题，对哺乳动物和酵母细胞周期调控的研究已经非常深入且日臻成熟；植物细胞周期调控研究起步相对较晚但近些年来在该领域也取得了很大的进展。

It is the home to a variety of wildlife, including the brown bears, the sika dears, the foxes, the Steller's sea eagles, the endangered Blackiston's Fish owl and the Viola kitamiana plant.

公园内是众多野生物种如棕熊、虾夷鹿、狐狸、虎头海雕、以及濒临绝种或当地特有的品种如毛腿渔鴞和知床堇等的天然生息地，对全球多种濒危海鸟、候鸟、三文鱼和海洋哺乳动物(如北太平洋海狮和部份鲸类)的生存繁衍亦十分重要。

Considering that fz6-related genes are consered between species, the same self-organizing system likely "applies to all mammals, and also to bird feathers and fish and reptile scale orientation," Nathans says.

考虑到fz6相关基因在种群中有保留，Nathans说，同样的自体组织系统可能&适用于所有的哺乳动物，也包括鸟类羽毛，鱼雷和爬行类鳞片的方向性。&

Nevertheless, the survey found that 93 percent of the streams and rivers with large piscivores exceeded that level of mercury deemed "protective" for fish-eating mammals.

不过，调查发现，有93 ％的河溪大piscivores超过这一水平的汞被视为&保护性&，为鱼类为主食的哺乳动物。

Instead of trying to keep down the body temperature deep inside the body, which would involved the expenditure of water and energy, desert mammals allow their temperatures to rise to what would normally be fever height, and temperatures as high as 46 degrees Celsius have been measured in Grant's gazelles.

除了尽量去保持身体深处的低体温，这将包括支出水和能量，沙漠哺乳动物们答应他们的温度上升到一个通常来说是发烧的温度并且温度高达46摄氏度，这已被在格兰特瞪羚测得。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
