幫翻一下 英翻中(20點)(不要翻譯軟體)

Note that in C. elegans hermaphrodite development there is a developmental switch ?first sperm are produced and stored in the spermatheca and then oocytes are produced. Oocyte nuclei are produced by meiotic cell division at the distal end of the gonad. They mature in a syncytium--without complete plasma membranes that separate them from one another. The nucleus and cytoplasm are completely enclosed in a plasma membrane later, just prior to fertilization. After fertilization, the eggshell is added. Fertilization takes place as maturing oocytes are squeezed through the spermatheca. Eggs develop in the hermaphrodite body briefly and then are laid through the vulva at about the 40-cell stage.

Here is a closer look at the organization of the hermaphrodite gonad:

Hermaphrodites have about 10eggs inside—the older eggs are laid about as fast as new eggs are made.

Oocytes pass into the spermatheca and are fertilized. Embryos develop in the uterus, and have a few cleavages before the eggs are laid, so the embryos have a few dozen cells when the embryos are laid. The embryos develop into worms over the next 8-18 hours(depending on temperature).

    注意在線蟲雌雄同體發育的過程中有一個發育上的關鍵:首先精子製造出來,儲存在藏精器中,然後再做出卵子來。卵子細胞核藉由減數分裂在性腺的遠端製造出來。

    They mature in a syncytium--without complete plasma membranes that separate them from one another.

    她們以融合細胞的形式成熟,彼此並沒有完整的細胞膜區隔開來。

    The nucleus and cytoplasm are completely enclosed in a plasma membrane later, just prior to fertilization.

    直到受精前卵子核和細胞質才被完全的被細胞膜包起來。

    After fertilization, the eggshell is added.

    受精之後,加上蟲卵殻。

    Fertilization takes place as maturing oocytes are squeezed through the spermatheca.

    當成熟的卵子被擠過藏精器時,「受精」就發生了。

    Eggs develop in the hermaphrodite body briefly and then are laid through the vulva at about the 40-cell stage.

    雌雄同體在蟲卵的過程相當短,大約在40細胞期就自生殖孔排出。

    Here is a closer look at the organization of the hermaphrodite gonad:

    這是雌雄同體的性腺組織的放大圖。

    Hermaphrodites have about 10eggs inside—the older eggs are laid about as fast as new eggs are made.

    雌雄同體內約有10個蟲卵,只要新蟲卵一做好,舊蟲卵便排出。

    Oocytes pass into the spermatheca and are fertilized.

    卵子通過藏精器,然後受精。

    Embryos develop in the uterus, and have a few cleavages before the eggs are laid, so the embryos have a few dozen cells when the embryos are laid.

    胚胎在子宮內發育,分裂幾次後蟲卵便排出,所以胚胎在排出時有數十個細胞。

    The embryos develop into worms over the next 8-18 hours(depending on temperature).

    再過8-18小時(視溫度而定)之後,胚胎便發育成成蟲了。

    注意在二形人發展有一滴發展開關?first 精液的C. elegans 被生產並且存放在spermatheca 和oocytes 然後被生產。Oocyte 中堅力量由meiotic 細胞分裂導致在性腺的末端末端。他們成熟在一個含胞體-- 沒有分離他們從互相的完全血漿膜。中堅力量和細胞質以後完全地被附寄在血漿膜, 在受精之前。在受精以後, 蛋殼增加。受精發生如同成熟oocytes 被緊壓通過spermatheca 。蛋簡要地顯現出在二形人身體和然後被放置通過vulva 在大約40 細胞階段。這仔細的審視在二形人性腺的組織: Hermaphrodites 有關於10eggs 裡面-- 更舊的蛋一樣快速地下像新蛋被製作。Oocytes 通過入spermatheca 和被施肥。胚胎顯現出在子宮體, 和有幾卵裂在蛋下之前, 因此胚胎有幾十二細胞當胚胎被放置。胚胎顯現出成蠕蟲在下8-18 小時(depending 在溫度) 。
