由细胞组成的

If the cell is that complex, what about the simplest organisms made up of these cellular structures?

如果细胞是这么复杂，那么由这些细胞结构组成的最简单的生物体又怎样呢？

It is lined by a single layer of cells, which vary in appearance from columnar to cuboidal.

Hypodermis One or more layers of cells that may be found immediately below the epidermis of plants.

下皮：是植物表皮下的一层或多层细胞，主要由大量薄壁的无色细胞组成。

It is composed of living parenchyma cells may be the origin of any organ in the plant a variety of organizations within living cells.

Below microscope we can see cork is by by tens of thousands be just as composition of alveolate dead cell, air was filled inside the cell, formed many a air tight gasbag.

在显微镜下我们可以看到软木是由成千上万个如同蜂窝状的死细胞组成，细胞内布满了空气，形成了一个一个的密闭气囊。

In fish and amphibia, the transition from maternal gene transcription to zygotic transcription happens during the time of midblastula formation, this stage is named by midblastula transition, at this period, embryo cell cycle composition changes, it is the first time to G1 time appearance, the cell cycle timelimit lengthens and the cell division synchronism loses, the large quantities of zygotic gene transcription starts.

鱼类和两栖类由母型调控向合子型调控过渡发生在中囊胚形成阶段，称为中囊胚过渡(midblastula transition，MBT)，胚胎细胞周期时相的组成在此期间发生变化，首次出现G1期，周期时限延长，细胞分裂的同步性丧失，大批合子型基因活化转录也在此时开始。

Horny layer is the outmost layer of epidermis, its thickness is decided by different parts of human body, it's about 0.02mm at the thinnest parts, and 0.5mm at the thickest. It is made up of 5-10 layers of enucleated cornified cells that contains keratin and horny fat, which has the capability of resisting weak acids and weak bases , they array closely and become a natural barrier to moisture content and some chemical substances, so as to prevent the water logging of bodily fluids and endosmose of chemical substances.

角质层是表皮的最外层，其厚度依身体部位的不同而定，最薄处约0.02mm，最厚处约0.5mm由5-10层含有角蛋白和角质脂肪的无核角化细胞组成，角质层细胞有抵抗弱酸弱碱的能力，角质层细胞排列紧密，对水分及一些化学物质有天然屏障作用，因而可以阻止体内液体的水渗和化学物质的内渗。

Thymosin 1（Tα1） is a acidic protein composed of 28 amino acid residues with isoelectric point 4.2 and molecular weight 3102.Its amino acid sequence is: N-Ser-Asp-Ala-Ala-Val-Asp-Thr-Ser-Ser-Glu -Ile-Thr-Thr-Lys-Asp-Leu-Lys-Glu-Lys-Lys-Glu-Val-Val-Glu-Glu-Ala-Glu-Asn-C. T1 is a T-cell potentiating factor.

胸腺素α1（thymosin 1，Tα1）是由28个氨基酸组成的酸性多肽，等电点4.2，相对分子量3108，其氨基酸序列为：N-Ser-Asp-Ala-Ala-Val-Asp-Thr-Ser-Ser-Glu-Ile-Thr-Thr-Lys-Asp-Leu-Lys-Glu-Lys-Lys-Glu-Val-Val-Glu-Glu-Ala-Glu-Asn-C[1，2]。Tα1具有多种免疫活性，可以促进T淋巴细胞的成熟和分化，促进成熟的T细胞、自然杀伤细胞分泌各种细胞因子如IL-2、INF-α等，同时也促使高亲和力白介素-2受体的生成[3-10]。

Histologically, all tumors were composed of compacted small uniform round cells, with honycomb nests and cell-free islands of neuropil matrix within the tumor.

组织由密集的小圆形细胞组成，胞浆透明，有核周晕，呈蜂窝状结构，并有无细胞性神经原纤维岛特征。

An adult Volvox consists of around2,000 body cells, whose job is to move the organism around using their flagella, and16 cells capable of reproducing.

一株成年团藻由大约2000个体细胞组成，它们用它们的鞭毛移动整个团藻，而16个细胞具有繁殖功能。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
