查询词典 chordates

Therefore, TH-regulated metamorphosis, mediated by TR, is an ancestral feature of all chordates.

文昌鱼的甲状腺素受体的表达水平也随着甲状腺素的增加而增加。

PROF.: Looked at more objectively, you could say the most complex animal group, the chordates

如果客观一点来看，你可以说最复杂的动物门，就是脊索动物，在最早期的时间里也出现

Therefore, TH-regulated metamorphosis, mediated by TR, is an ancestral feature of all chordates.

因此，由甲状腺素诱导的变态过程受到了甲状腺素受体的调节，这种变态过程是所有脊索动物的祖先特征，这种调节网络的保守性也支持变态在脊索动物谱系中是具有同源性的。

These sea squirts, though alien in appearance, are chordates and thus close relatives to not only Homo sapiens but also about 17,000 kinds of fish; 70 or so species of dolphins, whales, seals, sea lions and otters; some 10 kinds of sea turtles; and about 80 kinds of sea snakes.

这些海鞘，尽管看起来很怪异，但却是脊索动物因此不仅仅和现代智人是亲戚，而且也是17，000 种鱼的亲戚； 70种海豚，鲸鱼，海狮和水獭的亲戚； 10种海龟的亲戚； 80种海蛇的亲戚。

Metamorphosis in chordates is such an enigmatic character.

最近，一个由来自法国、波兰、斯洛伐克和美国科学家组成的跨国研究组对文昌鱼的变态发育进行了研究。

It seems that sea squirts do not, as we had thought, sit among the chordates , on the same evolutionary line as humans and other vertebrates .

海鞘好像不是我们原来所想像那样，座落于脊索动物的&门&中；它不像人类和其他脊椎动物（脊椎动物是脊索动物门中的一个&亚门&——译注）那样，落在相同的进化路线上。

In this "five-step", the evolution of the first step in the series of groups of animals very strange: 14 more haikou insect specimens comparative anatomy studies show that, they not only, and the lack of chordomas in skin, muscle, breathing, circulation, neural organs such as the system with the fundamental difference between the existing chordates, One of the most distinctive is the gills of six foreign composed of respiratory system, and this is the mouth of higher animals in the gills.

在这分&五步走&的演化系列中，&第一步&的动物类群十分奇特：对1400多枚海口虫标本进行比较解剖学研究表明，它们不仅缺少脊索构造，而且在皮肤、肌肉、呼吸、循环、神经等器官系统上与脊索动物存在着根本差别；其中最为独特的是其由6对外鳃组成的呼吸系统，这与较为高等的后口动物的勤鳃迥然有别。

These sea squirts, though alien in appearance, are chordates and thus close relatives to not only Homo sapiens but also about 17,000 kinds of fish; 70 or so species of dolphins, whales, seals, sea lions and otters; some 10 kinds of sea turtles; and about 80 kinds of sea snakes.

海鞘 这些海鞘虽然外观奇特，但是，它们是脊索动物，因此它们的近亲不光有智人，还有大约17000种鱼，以及约70种海豚、鲸鱼、海豹、海狮和水獭，还有约10种海龟和约80种海蛇。

The phylogenetic analysis based on the amino acids of invertebrate and vertebrate S19 proteins showed that the amphioxus protein was at the base of a clade of vertebrate S19 proteins, indicating that amphioxus is not only the sister group of extant vertebrates but also the basal lineage of chordates.

另外，AmphiS19与脊椎动物各S19蛋白在氨基酸水平上的相似性几乎是等同的。这些结果表明文昌鱼不仅是脊椎动物的姊妹类群，而且是脊索动物谱系进化过程中的基部类群。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
