家鄉(xiāng)的赤泥崗

家鄉(xiāng)地處偏僻的赤泥嶺，田地少得可憐。過(guò)去山崗上亂石重疊，荊棘叢生，水溝里的吸血螞蝗又軟又滑，叫人望而生畏，因此“泥地佬”成了家鄉(xiāng)人貧窮屈辱的代名詞。然而，這里的山山水水是我童年的樂(lè)園：山崗上有野石榴、野葡萄、“飯團(tuán)籽”、“老鼠齒”、山稔子……還有很多說(shuō)不出名的野果，甜酸苦辣，取之不盡，更有趣的是找鷓鴣蛋、燒蜂窩。吃蜂蛹就得講究方法了，還得有點(diǎn)勇敢的精神。而山腳下水溝里的田蟹、田螺、魚蝦便是我們的家常便菜。

       一年冬天，推土機(jī)在赤泥嶺上“噠噠”地響了個(gè)把月，當(dāng)我跑到那里一看，傷心極了——山崗上的亂石被推平了，我的“百果園”被摧毀了，鷓鴣也被嚇跑了。天啊，父親竟也在那群人里頭。

幾年后，原本石頭比泥土還要多的赤泥嶺竟然變成一汪蔗海，郁郁蔥蔥。涼風(fēng)吹來(lái)，綠浪翻涌，象向辛勤勞動(dòng)的人們點(diǎn)頭致意。還有一大片的果林，果實(shí)累累，果香沁人。昔日那些令人討厭的亂石被切成石磚，砸為碎石，黑黝黝的，*地流向四面八方，滾滾的財(cái)源不斷流進(jìn)千家萬(wàn)戶，“赤泥嶺”變成了“聚寶盤”。

     過(guò)去的崎嶇小路變成了寬敞的大道，低矮的茅房被嶄新的樓宇代替，世代沒(méi)有的教學(xué)大樓拔地而起……家鄉(xiāng)是鑲嵌在這塊土地上一顆璀璨的明珠。我也再不當(dāng)初那些把赤泥嶺弄得翻天覆地的墾荒者，看到他們油然而生敬意。

如今，“泥地佬”聽(tīng)起來(lái)不再刺耳，我為做一個(gè)“泥地佬”而驕傲。我的夢(mèng)魂常牽繞著家鄉(xiāng)那一片赤泥嶺……

從中排出的“卵”其實(shí)是次級(jí)卵母細(xì)胞。*極體和次級(jí)卵母 細(xì)胞一同排出。次級(jí)卵母細(xì)胞進(jìn)入輸卵管后，在輸卵管中進(jìn)行第二 次減數(shù)分裂。這次分裂要在受精之后，在精子核進(jìn)入次級(jí)卵母細(xì)胞 之后進(jìn)行。分裂的結(jié)果，和*次一樣，只產(chǎn)生一個(gè)有效的大細(xì)胞 ，即卵細(xì)胞，以及一個(gè)不能受精的極體。結(jié)構(gòu)功能編輯女性排卵時(shí)，卵子從破裂的卵泡中隨卵泡液一起從卵巢排出(排卵) ，被輸卵管傘端所拾取并運(yùn)送至輸卵管壺腹部，等待精子受精。這 時(shí)的卵子其實(shí)是卵冠丘復(fù)合體。該復(fù)合體的中心是卵母細(xì)胞以及一 個(gè)體積相對(duì)小得多的極體，其外包裹著一層主要由卵母細(xì)胞分泌物 形成的細(xì)胞外基質(zhì)，稱為透明帶（簡(jiǎn)稱ZP)，卵母細(xì)胞與透明帶之 間留有一狹窄的空隙即卵周間隙。透明帶之外還圍繞著若干層卵泡 細(xì)胞，其zui靠近透明帶的一層被稱為放射冠。透明帶在受精中起著 至關(guān)重要的作用，其結(jié)構(gòu)主要由三種糖蛋白(ZP、ZP、ZP)組成 。其中，ZP能識(shí)別同物種精子并與之結(jié)合，繼而誘導(dǎo)精子發(fā)生頂 體反應(yīng)，啟動(dòng)受精過(guò)程。若未受精，卵母細(xì)胞將在排卵后～  h退化。輔酶是一大類有機(jī)鋪助因子的總稱，是酶催化氧化還原反 應(yīng)、基團(tuán)轉(zhuǎn)移和異構(gòu)反應(yīng)的必須因子。
The "egg" that is discharged from it is actually a secondary oocyte. The first polar body is discharged together with the secondary oocytes. After the secondary oocyte enters the fallopian tube, a second meiosis is performed in the fallopian tube. This division takes place after fertilization after the sperm nuclei enter the secondary oocyte. As a result of the division, just like the first time, only one effective large cell, the egg cell, and a polar body that cannot be fertilized are produced. Structural function editing Female ovulation, the egg from the broken follicle together with the follicular fluid from the ovary (ovulation), picked up by the fallopian tube umbrella and transported to the fallopian tube ampulla, waiting for sperm fertilization. The egg at this time is actually a cumulus dome complex. The center of the complex is the oocyte and a much smaller volume polar body, which is surrounded by a layer of extracellular matrix mainly composed of oocyte secretion, called the zona pellucida (abbreviated as ZP), and the oocyte. There is a narrow gap between the cells and the zona pellucida, which is the gap between the eggs. The zona pellucida also surrounds several layers of follicular cells, and the layer closest to the zona pellucida is called the corona radiata. The zona pellucida plays a crucial role in fertilization. Its structure is mainly composed of three glycoproteins (ZP, ZP, ZP). Among them, ZP can recognize and combine spermatozoa of the same species, and then induce acrosome reaction in spermatozoa and initiate fertilization. If not fertilized, oocytes will degenerate after ovulation ~ h. Coenzymes are the general term for a large group of organic cofactors, and are essential factors for enzyme-catalyzed redox reactions, group transfer, and isomerization reactions.
