除非人类不用化妆品或者不再研究对人类有益的那么可以不用可惜当前就是这样如果动物智慧比人类高我们也会被拿去研究的~

不知道你的是什么实验?还有,如果你做实验的话,有好多的限制,如果是医学实验的话去买些小白鼠,如果是化学实验,有毒有害的,建议不要去做。有相关的政策法规的。你可以去查阅一下。

动物研究英语作文可以写为了探索大自然的奥秘,为了扩大人类的视野,为了增长智慧,为了发明创造,有时应当把动物当做老师。比如雷达的发明,就是在研究蝙蝠的基础上一步步创造出来的。潜水艇是在研究鱼为什么会沉入水中、又为什么浮到水面的基础上创造出来的。过去一个多世纪,医学和生命科学取得了飞跃式的发展,人类不仅建立了麻醉、安全输血、器官移植、人工心脏瓣膜等医疗技术和手段,还研发出了抗生素、疫苗和各种药物,从而消灭或控制了多种疾病,所有这些成就的取得都离不开动物实验的支持。很多介入性的实验无法在人类身上进行,而诸如小鼠、大鼠、兔、猪、猫、狗和猴等实验动物不仅在遗传组成上与人类高度同源,而且具有和人类相似的器官和系统,并以大致相同的方式完成其生理功能,同时还会患与人类疾病类似的各种疾病。因此科学家可以通过动物实验来模拟人类的生理活动及疾病发生和发展的过程。以诺贝尔生理或医学奖为例,截止到今年,在219位获奖者中,有183位的工作与动物实验相关。比如本公众号前面介绍过的德国科学家冯贝林基于豚鼠实验,建立了白喉毒素抗血清和抗血清疗法,并因此获得了首届诺贝尔生理或医学奖豚鼠-早期感染实验的明星动物。

In order to explore the mysteries of nature, expand human vision, increase wisdom and invent, animals should sometimes be regarded as 为了探索大自然的奥秘,为了扩大人类的视野,为了增长智慧,为了发明创造,有时应当把动物当作老师。For example, the invention of radar was created step by step on the basis of the study of Submarines are created on the basis of studying why fish sink into the water and why they float to the 比如雷达的发明,就是在研究蝙蝠的基础上一步步创造出来的。潜水艇是在研究鱼为什么会沉入水中、又为什么浮到水面的基础上创造出来的。The main reason for using model animals in research is the principle of evolution, that is, all organisms have a certain degree of correlation and genetic similarity due to their common 在研究中使用模式动物的主要原因是进化原理,即所有生物由于共同的祖先而具有一定程度的关联性和遗传相似性。Therefore, the study of Human Kinship classification can provide a lot of information about human mechanisms and diseases, which is useful in 因此,对人类亲缘分类的研究可以提供大量关于人体内机制和疾病的信息,这些信息在医学上是有用的。

With human beings on Earth since then, we continue to evolve at the same time has been hurt those lovely They did not at fault, they are only in accordance with the laws of nature live in But since the existence of mankind , their homes become increasingly Some animals have even become In the extinction of animal, the thylacine is the Thylacine in a long time ago to live in the vast prairie, they have been very happy, Since the arrival of human beings have changed their Due to the large number of human enclosure, livestock grass makes less and less change to many herbivores to move to other This herbivorous animals to eat the wolf bag, there is no They steal human Farmers would hate the wolf from the bag, see a killing one, on this last one wild thylacine was also When people should be aware of extinct thylacine, the protection of the park began last a thylacine, it thylacine only 48 days before the final And 48 days later, the Forever thylacine disappeared from the Earth, the Forever! Of course, not all animals are extinct human killing, some changes in the environment are not suited However, the extinction of some animals, human beings have an unshirkable Since ancient times human beings have been cruel to those animals alone, human deprivation of their right to Now seems to have been aware of the extinction of an animal In order to make money, what people are willing to do so, they sell fur animals, shopping malls, the meat of animals sold to But we can not shirk all responsibility to the heads of traders, consumers also have the responsibility, if there is no consumer demand then the traders will not take the Human beings are still eating wild For example: the If the extinction of the snakes, rats would wantonly breeding, then how do we So each has its biological significance of the existence, they are in the natural law of If a broken food chain, then another will wantonly breeding animals, and even a threat to humanity, we bear in mind the protection of The protection of animals is to protect human beings themselves!参考译文:自从地球上有了人类以后,我们在不断地发展进化的同时也在不断的伤害着那些可爱的动物们他们没有过错,他们只是根据自然界的法则和平的生活着可是自从有了人类的存在,他们的家园变的越来越小有些动物甚至已经灭绝了 在灭绝的动物里,袋狼算是最惨的了。在很久以前袋狼生活在广阔的大草原上,它们过的很快活,无忧无虑。自从人类的到来改变了它们的生活。由于人类的大量圈地,饲养牲畜使得绿草变地越来越少,许多食草动物迁徙到别的草原上。这样以草食性动物为食的袋狼就没有了食物。它们便去偷人类饲养的动物。农场主便痛恨起了袋狼,见一个杀一个,就这样最后一只野生袋狼也被杀死了。当人们意识到袋狼就要灭绝时,才开始保护公园里的最后一只袋狼,这只袋狼才过了最后48天的好日子。而48天后,袋狼永远的从地球上消失了,永远的! 当然不是所有灭绝的动物都是人类杀死,有的是不适应环境的变化而灭绝的但是某些动物的灭绝,人类有着不可推卸的责任。人类自古以来就一直残忍地对待着那些动物们,人类剥夺了它们生活的权利 现在人们似乎还没有意识到一种动物的灭绝的危害。为了赚钱人什么都愿意做,他们把动物的皮毛卖到商场,把动物的肉卖到餐馆。但是我们不能把一切责任都推卸到商贩的头上,消费者也有责任,如果没有消费者的需求那么商贩也不会铤而走险。人类还在吃着野生动物。比如:蛇。如果蛇灭绝了,老鼠会大肆繁殖,到那时候我们该怎么办…… 因此每一种生物都有它存在的意义,它们都在以自然的法则生存。如果生物链的一头断了,那么另一种动物就会大肆繁殖,甚至威胁到人类,大家记住保护动物。保护动物就是保护人类自己!With human beings on Earth since then, we continue to evolve at the same time has been hurt those lovely They did not at fault, they are only in accordance with the laws of nature live in But since the existence of mankind , their homes become increasingly Some animals have even become In the extinction of animal, the thylacine is the Thylacine in a long time ago to live in the vast prairie, they have been very happy, Since the arrival of human beings have changed their Due to the large number of human enclosure, livestock grass makes less and less change to many herbivores to move to other This herbivorous animals to eat the wolf bag, there is no They steal human Farmers would hate the wolf from the bag, see a killing one, on this last one wild thylacine was also When people should be aware of extinct thylacine, the protection of the park began last a thylacine, it thylacine only 48 days before the final And 48 days later, the Forever thylacine disappeared from the Earth, the Forever!

仙人掌浑身是宝,用途广泛,它的嫩茎可做蔬菜食用,加工成50多种仙人掌菜肴。仙人掌的茎片可以加工成片剂,胶囊、饮料等保健食品。根据中国医学科学院药用植物研究所研究结果表明,仙人掌含有丰富的矿物质、蛋白质、纤维素和钙、磷、铁、维生素C、维生素B,能帮助消除人体内多余的胆固醇,起到降低血糖、降低血脂、降血压之功效,有清热解毒,排毒生肌,行气活血等保健作用。种植食用型仙人掌生产成本低,不需农药和化肥,无污染,属于绿色有机食品。 仙人掌能在没有水,没有花草树木的沙漠之中生长,这是为什么? 带着强烈的欲望,我认真探究着仙人掌能在沙漠中成长的“秘密武器”。我翻阅百科全书,知道了为什么在一向被称为“不毛之地”的沙漠里,仙人掌却能够傲然生存,繁衍不息:仙人掌在干旱的环境中,叶退化成针状,以减少水分的蒸发;茎肥厚多汁,有发达的薄壁组织细胞贮藏丰富的水分;茎的表皮有厚而硬的蜡质作为保护层,或生有密集的绒毛,保护它不受强光的照射,降低水分蒸发。仙人掌的根分支多,根系庞大,能吸收降落不多的雨水。一遇降雨,它就会在表土层长出许多新根,大量吸水。它的大根有很厚的木栓组织保护,能在灼热的沙石上生活而不至于干死。有人实验,6年不给仙人掌浇水,它还顽强的生活着。据说一些大仙人掌的寿命可达数百年。世界上最大的仙人掌,高达15—18米,直径30—60厘米,重10余吨,里面可以贮藏上千公斤的水。行人口渴了,就可以随时挖取多汁的茎肉解渴。 除此之外,我还调查到:食用仙人掌不仅营养丰富,而且具有较高的药用价值,可加工成多种保健品,还是制作罐头、饮料、酿酒的上等原料。食用仙人掌的吃法很多可采用煎、炒、炸、煮、凉拌等多种烹制方法。它在欧洲、非洲的许多国家及日本颇受青睐。 一般都说仙人掌植物的刺是仙人掌植物为抵抗干旱,减少水份蒸发,而由叶片退化而成。此学说显然是错误的。观察仙人掌植物的原始种之一的有叶的叶仙人掌(Pereskia aculeata),叶和刺都是它的器官,叶生于刺的下边。当叶脱落后,脱叶处不再长出新叶,而刺却不脱落。二年生以上的枝条上只有刺无叶。掌状的仙人掌新发的掌上,叶进化成粗短的针刺状叶亦长在刺下边。当掌长得比较厚实(一般新掌长出一个多月)时,粗短的针刺状叶就发黄脱落,在掌上只剩下刺由此知叶和刺是仙人掌植物的两个不同的器官,刺非叶退化而成刺是仙人掌植物防动物吞食的自卫武器。 仙人掌的刺有保护自己和帮助繁衍后代的作用,所以一般都有刺。但也有一些种类没有刺的,,如星球、乌羽玉、龟甲牡丹等,但它们也有刺座。还有一些种类小时侯有刺,长大后就脱落,更有的幼时无刺,到老龄植株时刺却长出来了。

世间有许许多多的生物体,世界因生命而精彩。生物形态各异,很有趣,比如,翩翩起舞的蝴蝶,讨厌的苍蝇,可爱而会唱歌的小鸟,还有6500万年前灭绝的恐龙,它们的种种生命迹象都吸引了我的视线,让我对生物有了好奇心。以前,我对“生物”的理解只是单纯的“动物”,上中学学习了生物后,我知道生物的范围很广,不止动物,植物、微生物都在其之内。地球上的植物大约有30多万种,动物约有150多万种。从生物书上,我知道了桫椤、蕨、苏铁等不常见的植物,还解决了小时候一些弄不懂的问题。有一次,我在比较干的泥土里挖蚯蚓,却怎么也挖不着,现在才知道蚯蚓生活在阴暗潮湿的地方,干地里当然挖不着了。为什么仙人掌的叶子会退化成刺呢?因为它需要适应环境,为了减少水分的丧失,储存更多的水分,仙人掌的茎部也变得肥厚而多汁。生物这门学科帮助我 了解了疑难的问题,这是我喜欢生物的原因之一。走进第二单元,我认识了显微镜。在我心目中,显微镜是那样地奇妙,一直都想用它观察东西,小学时从来也没碰过它。记得第一次进生物实验室,看见桌上的显微镜,有一种难以抑制的喜悦。于是我迫不及待地凑到目镜前看了看,可看到的只是一片黑暗。上课时,老师说,用显微镜观察东西并不是想象得那么简单,要经过对光、选择物镜、制作临时玻片标本、调整清晰度等几个环节。我仔细地听着,努力熟记其结构的每一个名称。在老师的帮助下,我终于通过显微镜看到了细胞。当时就有一种巨大的成就感,仿佛自己也成了一个科学家,会用显微镜观察微生物了!还有一个奇怪的现象,在显微镜下呈的是倒像。现在,使用显微镜已成了家常便饭,几乎每节课都要做实验。用显微镜观察肉眼看不到的东西能使我快乐,这也激发我学习生物的兴趣。此外,我还对生物体有了新的认识。除病毒外,生物都是由细胞构成的。在显微镜下看到的细胞是一个个排列在一起的。植物细胞由细胞壁、细胞膜、液泡、细胞核、线粒体、细胞质、叶绿体构成,动物细胞由细胞膜、细胞质细胞核、线粒体构成,它们的作用也各不相同。细胞核由染色体构成,染色体由DNA构成……别小看一个小生命,它的结构复杂得很呢!以前,我不知道水果中的水分是从哪儿来的,原来是来自液泡中的细液泡。我总是生病,学习了生物后我知道是病毒在我身体里捣鬼!连病毒都是生物体,真是不可思议啊!我对生物越来越有好奇心了。生物学把我带进了一个奇妙的世界,解决了疑难的问题使我豁达,使用显微镜让我感到快乐,微生物使我有了好奇心,因此,我对生物这门学科产生了浓厚的兴趣。

动物行为学的论文挺好写的,前年在学校还写过。上网找几篇,有个重点就行了

科学小论文范文 鱼会说话吗? 您相信鱼会说话吗?这是一个耐人寻味的事,我想知道鱼是否会说话? 我家买了两条小金鱼,一条是全黑的,黑的叫乐乐,因为它很快乐。一条红白相间的名字叫欣欣,因为它懂得欣赏,很好玩吧!他俩生活在鱼缸里,这个鱼缸可“非比寻常”。里面有山、花、树、贝壳、彩色石头……。很美吧!让我们一起来观察它! 9月23日凌晨五点左右,我正要去喂食,我看见这么一个现象,我把鱼食撒到鱼缸里,乐乐吃了一点就不吃了。 9月23 日傍晚5 点15分,我看见鱼缸里的贝壳反过来了,小欣欣看见了,好像以为它——这个小贝壳要死了,连忙游过去,用它的头去抵,抵了近三、四分钟,它就不抵了,它游到乐乐旁边,用自己的尾巴扫了扫乐乐,然后互相碰了一下头,乐乐和欣欣一起游过去,把那块贝壳一起弄回原样了,这一点证明了“团结力量大”。 通过两次的观察,让我知道了人类有人类的表达方式和交流语言,动物也有自己王国的表达方式和交流,这也告诉了我们,如果你不团结,那么你将一无所有,朋友之间的友谊真伟大。同时,我们也要多观察,多发现,但是不能因为你在动物身上作试验,就伤害小动物,因为动物是人类的朋友。 蚂蚁为什么不会迷路? 蚂蚁,相信大家都很熟悉。那又有谁能真正地了解蚂蚁呢?蚂蚁为什么不会迷路呢? 带着这个问题,我查阅了一些书籍。书上说,蚂蚁从蚁穴出发到达目的地后,沿途会留下一些气味,返回蚁穴。用触角相互碰一下,通知其他的蚂蚁。科学家曾经就这个问题作了一个试验。科学家先确定一只蚂蚁,将他沿途到达目的地的地方用力擦干净。当这只蚂蚁返回时,在被擦去气味的地方突然间停了下来。原地边转圈边寻找着什么。从而得到蚂蚁是靠气味来辨别方向的。 我为了证实这个结论,我做了个试验。我首先准备了一个十厘米左右的细小树枝,在树枝的一头放上一个诱饵——小糖果。我把这个装置放在一个蚁穴附近。不一会儿,有一只蚂蚁出来探路了。我把他引上木棍后,他到达了糖果的地方,仿佛在闻一闻、嗅一嗅。我趁此机会将木棍的中断部分截下一厘米的木棍。当这只蚂蚁返回的时候,就在被截去的地方左转右转,就是找不到回家的路。 过了一会儿,我又重复了上面的试验,蚂蚁仍然没有找到回家的路。通过这两次实验,我终于知道蚂蚁为什么不会迷路的秘密了。原来蚂蚁是根据气味来辨别方向的。 知道了蚂蚁的这一秘密后,我在想:是否我们可以制作一种蚂蚁报警器呢?当蚂蚁走到报警器附近时,报警器就能“闻”出蚂蚁的气味,然后发出鸣叫声,让我们知道蚂蚁跑到橱柜里了或其他地方 。 蛋壳的秘密“同学们,蛋壳都带来了吗?”老师问。“带来了!”我们异口同声地回答。 为了今天的科学课,老师让我们带蛋壳来。带蛋壳做什么呢?是做不倒翁吗?我们都很好奇。“今天,我们要用这两个半截蛋壳做一个小实验。做之前,请大家先猜猜,我用这枝铅笔朝着蛋壳垂直往下刺,是口朝上的蛋壳先破呢,还是口朝下的蛋壳先破?”“当然是口朝下的先破!”大多数同学都抢着回答。“口朝上的先破!”同桌偏要和大家作对。老师微笑着说:“那好,下面我们就来做做实验,看谁的答案才是正确的。” 老师叫了一名同学上讲台,让他用铅笔对准自己手上口朝上的蛋壳。老师一声令下,同学手一放,铅笔刺到了蛋壳上,蛋壳没有破。老师又让他试了几次,铅笔第三次刺下的时候,终于刺破了蛋壳。接着,老师又让他用铅笔刺口朝下的蛋壳。“一下、两下、三下……”我们一起数着;但那半个蛋壳就像穿了盔甲一样,被刺了十几下还是不破。 “耶!我猜对了!”同桌高兴得手舞足蹈。虽然我们都不服气,但经过多次试验,我们发现,同样的两个半边蛋壳,用铅笔垂直去刺,的确是口朝上的比较容易破。老师告诉我们,这是因为口朝上的蛋壳受力比较集中,而口朝下的蛋壳受力分散,所以就比较坚固。难怪建筑工地里的工人叔叔们都戴着口朝下的安全帽,原来就是这个道理啊! 小朋友,看清楚喽,我先写这篇论文的,别把复制我的那人给满意了不然我会恨失望,我们都是同龄人,帮助一下啦,我13岁,如果有神马问题的话。加Q:2281091542,我随时帮你解答语文难题哦

2005年夏的一天,我在家里悠闲地待着,觉得无聊,便找了一个凸透镜开始玩了起来。一会儿把吊兰放大,变成巨大的草丛;一会儿又把小鱼放大,变成一条巨大的“鲨鱼”……不久,我玩累了,就随手把凸透镜放在桌子上。不一会儿,妈妈过来看我了,她看到放在桌子上的凸透镜后,急忙把它收起来,还对我说:“栋栋,以后别把凸透镜放在受阳光直射的地方,很容易着火的!”听了这话,我心想,凸透镜为什么能使物体着火呢?我就问:“妈妈,凸透镜怎么会使物体着火呢?”妈妈回答说:“因为凸透镜对光线有会聚作用,太阳光可以看作平行光,平行光通过了凸透镜后就会聚于一点,这一点也就是焦点。这一点产生大量的能量,达到一定温度就能够把易燃的物体烧起来。”听了妈妈的话,我有点半信半疑。于是我决定自己亲手做一个实验!我先把纸平铺在地上,再用凸透镜把光聚集在纸上。可光却偏偏不听我的话,我要它聚在一起,它却偏偏散开来,开状就象扫把星。不过我还是有耐心的,一会儿向左偏一点,一会儿又向右偏一点,终于,我成功地把太阳光给浓缩成了一个小小的光点。好一会儿纸还没有烧着,我想,会不会是太阳光不够热呢?于是我便用手摸了一下纸,哇!差点烫伤了我的手。我只好先回到家里。后来,我从书上查到:“白色的物体容易反射光线,而黑色的物体容易吸收光线!”我高兴极了,决定用黑纸做第二次实验。同第一次实验一样,我也是先把纸给平铺在地上,再熟练的把角度调到最佳位置,让阳光变成一个小小的圆点。最全我等了一会儿,纸果然烧了起来。我终于明白了:原来太阳光
