雄性

In this study, the male sterile female fertile mutants-S903Bwas the new one in spring soybean with relatively short growth period. It canbe used in soybean recurrent selection program and has its potential in soybeanbreeding. Anyhow, it is essential to take allelism tests if S903B mutant wasallelism with 〓 to 〓.

本研究所发现和研究的S903B雄性不育系，为我国南方春大豆中第一个较早熟的隐性核不育大豆基因型，表现为雄性不育、雌性可育，在大豆的轮回选择育种中应有巨大的利用潜力。S903B突变体是否与〓-〓等位，还需进行等位性测验。

The profile of liver CYP450 induction by DEX in male rat After 4 daily i.p. administering of 0,25, 50 and lOOmg/kg/d DEX in male Wistar rat, it was determined the total CYP450 content, the mRNA and protein expression levels of CYP3A1, CYP3A2 and CYP2B1/2, and the ERD (CYP3A catalytic activity), PROD (CYP2B catalytic activity) and BROD (total CYP450 catalytic activity) in livers.

DEX对雄性大鼠肝脏CYP450的诱导效应雄性Wistar大鼠腹注0、25、50和100mg DEX/kg/d诱导处理4天后，测定大鼠肝脏总CYP450含量，CYP3A1、CYP3A2和CYP2B1/2的mRNA及蛋白表达水平，肝脏红酶素脱甲基酶(ERD，CYP3A活性)，苄氧基试卤灵脱乙基酶(PROD，CYP2B活性)，苯氧基试卤灵脱乙基酶(BROD，总CYP450活性)，结果表明，CYP450含量、ERD、PROD和BROD在DEX多次诱导后都有升高，CYP3A1 mRNA表达水平、蛋白含量和酶活性有明显的升高，剂量效应关系明显；CYP3A2蛋白也有明显升高，而其mRNA表达水平却没有变化，提示CYP3A1和CYP3A2的诱导机制可能不同。

Scorpion males save themselves by stinging their partners into submission, mantises wait until a female has fed to approach her and spiders actually bring an offering of food in the hope that they themselves will not be the main course.

比如，蝎子的最大敌人竟然是自己，超过一半的雄性沙漠蝎子都是死于交配完成之后的雌性配偶。不过，雄性蝎子自有策略，在与雌性发生性交配前会蛰一下雌性，让雌性完全屈服，以避免雌性交配完成后将其完全吞食。而雄性蜘蛛为了避免不被雌性吞食，它们会用爪子紧紧抓住雌性蜘蛛的下颚，或者为雌性带来了一些食物，从而转移雌性的注意力。

For example, if a pair of blue-throated males are protecting their territory from orange-throated bullies.

举例来说，如果两只蓝喉雄性侧边斑点蜥蜴正在保护其领地不受喉咙为橙色的雄性蜥蜴的侵犯时，那么其中一只蓝喉雄性蜥蜴将会忘我地上前迎战入侵者。

But one possibility is that, in a species in whichfemales routinely mate with several males, chimerism evolved as a way of dupingmales into looking after offspring that are not their own.

但是有一个可能是，在某些物种的世界里，雌性动物会通常与好几个雄性动物交配，而嵌合现象就逐渐成为蒙骗雄性动物的一种方式–雄性动物就此会好好照顾那些不属于自己的子女。

Methods: Kuming mice has been employed in this experiment, which divied into several groups. the blood lactate, blood urea nitrogen and glycogen were detected after loading swimming .

方法和结果：本课题通过对实验组、对照组的雄性昆明种小鼠负重游泳后的血乳酸水平的差异与变化；实验组、对照组的雄性昆明种小鼠游泳后血清尿素氮的差异与变化；实验组、对照组的雄性昆明种小鼠肝糖原含量的差异与变化，来判定受试物是否具有抗疲劳的作用。

In the animal world, a male's sex organ is called penis. The plural form of 'penis' is either penes or penises. These are not figurines. These are different male reproductive organs of different animals.

奇形怪状的雄性生殖器在动物界，雄性生殖器叫做阴茎，英文复数形式是penes or penises，下面这些图片不是小雕像，它们是不同动物的雄性生殖器官。

最初，雌性蜥蜴也会允许年轻雄性与之交配，只要不被体型较大的、占有欲强的成年雄性发现，否则这些成年雄性蜥蜴会驱赶和撕咬年轻的对手。
