在动物漫长的进化历程中，昆虫纲作为动物界种数最多的一类，约占动物现存种的五分之四。 |
| 5. | We can tell from fossil evidence in rocks that many living species have become extinct over the millions of years since life began
我们从岩石中的化石遗留下的证据中可以辨别出来，自从地球上有生命时开始，在若干个百万年中，有很多动植物的物种已经逐渐地灭绝了。 |
| 6. | While these forests cover only five percent of the surface of the earth , they contain about one - half of the world ' s living species of planets and animals , and many of these species may become extinct

| 7. | Learning strategies is procedure , law , way , technique and adjust methods during effective learning . it is researched , unsuitable or wrong strategies make students lose interests so as that research on living species change into corpse study

| 8. | Cycadophyta ( cycads ) a phylum of cone - bearing gymnosperms ( about 75 living species ) with palmlike compound leaves and special coralloid roots at or near the ground surface , which contain symbiotic nitrogen - fixing cyanobacteria
苏铁纲（苏铁类植物） ：包含球果的一类裸子植物（现存种大约有75种） ，它们具有掌状的复叶，在近地面处有特殊的珊瑚状的根，根内含有共生的固氮蓝细菌。 |
| 9. | 2 . the sequences variation of mitochondrial 12s rrna gene and phylogenetic relationships of anseriformes were studied based on the complete 12s rrna gene sequences of 36 living species of which 19 species were sequenced and other related data obtained from genbank
2 、研究测定了雁形目( anseriformes ) 19种mtdna12srrna基因全序列，结合genbank中雁形目种类相关数据，分析了雁形目36种鸟类12srrna基因序列变异及其分子系统发生。 |
| 10. | And a back - of - the - envelope calculation based on the 1 . 8m sorts of organism recognised so far as species under the linnaean system , on the rate at which new species are being discovered and on such ecological matters as the average number of parasites ( themselves new species ) that each free - living species harbours , suggests the final total may be around 30m
一个以三部分，即：在林耐分类系统中迄今为止被认定是物种的180万种微生物、新物种的发现速率和诸如在每个独立生存的物种中藏匿的平均寄生虫数量（它们本身也属于新物种）等生态因素，为基础的估算表明全球物种的总数是在三百万左右。 |
