A male usually has a broader head, a blacker beard and is more dominant.

雄性的头比雌性的宽，下巴上的刺比雌性的黑并且更加霸道。

He will wrap his tail around her and insert his hemipene into the female's cloaca.

雄性会把尾部缠绕靠拢雌性，并把半阴茎伸入雌性的泄殖腔。

Methods: Female genitalia of 52 species of Chinese Culex mosquitoes were dissected and glass-slices of the specimens were prepared, on which a comparative analysis was conducted.

目的：探索我国库蚊雌性尾器的分类学价值。方法：常规方法制备我国库蚊属52种雌性尾器玻片标本，并分析比较。

After fed for 3, 6 and 12 months respectively, 15 SHRs(6 females, 9 males) and 15 Wistar-Kyoto rats(7 females, 8males) were sacrificed to measure the blood pressure and determined plasma NO levels with the silver nitrate deoxidize method.

选择SHR 30只，雌性6只，雄性9只；大鼠WKY 30只，雌性7只，雄性8只。

objective:to investigate the influence of soybean isoflavones on the antioxidative effect and improving the ability of study and memory in climacteric rats.methods:forty-eight female sd climacteric rats were randomly divided into 4 groups with one control group and the other low,medium and high dose groups,which were given soybean isoflavones 0 mg/kg.bw,42 mg/kg.bw,83 mg/kg.bw and 249 mg/kg.bw by superalimentation daily for 60 days respectively.the levels of sod,gsh-px and mda in serum were measured,and the ability of study and memory in each group was deterimined by adopting the law of diving platform.results:the content of serum mda in medium and high dose groups was lower than that in control group.the activity of serum gsh-px im medium and high dose groups was significantly increased,so was the activity of serum sod in low,medium and high dose groups.conclusion:soybean isoflavones do have the obvious effect of antioxidation,and improve the ability of study and memory effectively in female sd climacteric rats.

目的：观察大豆异黄酮对更年期雌性sd大鼠抗氧化作用及学习记忆的影响。方法：选用健康更年期雌性sd大鼠，随机分成空白对照组和低、中、高剂量4组。空白对照组给予蒸馏水，实验组每日分别灌服42、83、249 mg/kg剂量的大豆异黄酮，连续60d。第60d取血测定血清过氧化脂质丙二醛含量、超氧化物歧化酶活力、谷胱甘肽过氧化物酶活力，用跳台实验方法测定大鼠学习记忆能力。结果：与空白对照组比较，中、高剂量组大鼠血清mda含量显著降低，低、中、高剂量组血清sod活力明显升高，中、高剂量组血清gsh-px活力明显升高。结论：大豆异黄酮具有明显的抗氧化作用，并有效提高更年期雌性sd大鼠的学习记忆能力。

The amount of different mineral elements in different parts of male and famale B. thoracica had big difference, except Zn; the amount of other mineral elements in female breast muscle were all higher than that in male breast muscle, and the amount of Ca, Fe in leg muscle, Ca, Cu, Mn in skeleton and Cu, Mn in feathers of male were all higher than that of female, but the amount of Ca, Fe, Zn in feathers of female were higher than that of male.

雌雄个体不同部位、不同矿质元素含量存在较大差异，除Zn外，雌性胸肌中其他元素的含量高于雄性，雄性腿肌中Ca、Fe含量、骨骼中Ca、Cu、Mn含量、羽毛中Cu、Mn含量均高于雌性，雌性羽毛中Ca、Fe、Zn含量高于雄性。

How the Males Escape: The best known self-preservation tactic for male mantises is simply waiting until their partner has caught a snack - and to hoping she isn't still hungry after they finish copulating.

雄性如何逃脱：雄性螳螂的自卫策略就是简单地等待雌性到来，然后将它们吞食，或许雄性不被雌性吞食的最大可能性就是在雌性完成交配后并未感到饥饿。

It's the first time to discover the existence of variated flowers in syconia of Ficus awkeotsang Makino. There were two types of variated flowers in morphology : umbrella-inflorescence-shape and solitary.The variated flowers in female syconia grew in female flower area and degenerated flower area, with female, female degradation or hermaphrodite degradation. The variated flowers in male syconia grew in the gall flowers area with 95.68％ male structure and 4.32％ female structure.

首次发现爱玉子花序中变异花的存在，在形态上有伞形花序状与单生两种类型，雌花序中的变异花分布在雌花区和退化花区，为雌性、雌性退化或两性退化结构；雄花序中的变异花均生长在瘿花区，其中95.68％为雄性结构，4.32％为雌性结构。

Others believe that her scent is an air-borne chemical emission. This latter theory is supported by the fact that the female is not very active during this time and males come to her from all directions. Males have also been observed flicking the air to pick up the chemical presence.

有些科学家相信雌性留下了生化激素来吸引雄性，另外一些则认为雌性气味的化学成分是靠空气传播的，这一理论的有利证据就是雌性在发情期并不主动而雄性从四面八方赶来这一事实。

然后把分别带有雄性或雌性气味的雌性和假雌性蜥蜴全部放到典型的成年雄性蜥蜴面前。
