山东省郓城县随官屯镇初级中学2016-2017学年八年级上学期第一次月考生物试题(解析版)

山东省郓城县随官屯镇初级中学2016-2017学年八年级上学期第一次月考生物试题(解析版)

2016-2017上学期八年级生物第一次质量检测一、选择题部分1. 植物果实内的种子数目取决于A. 受精卵的数目和子房内胚珠的数目B. 子房内胚珠的数目C. 受精极核的数目D. 花粉里精子的数目【答案】B【解析】试题分析:实和种子的形成如图所示:由图可知果实中种子的多少是由胚珠的多少决定的。

考点:果实和种子的形成。

2. 取一粒浸软的玉米种子(果实),用刀片将种子从中央纵向剖开。

在剖面上滴一滴稀释的碘酒,再用放大镜仔细观察,被碘酒染成蓝色的是A. 果皮和种皮B. 胚C. 胚乳D. 胚芽、胚轴、胚根、子叶【答案】C【解析】试题分析:淀粉遇碘液变成蓝色,玉米种子中的营养物质是淀粉,玉米种子的营养物质主要储存在胚乳中,所以在玉米种子剖面上滴一滴碘酒,被碘酒染成蓝色的是胚乳,故选C。

考点:种子的结构。

3. 我们在吃玉米果穗时,常会发现有缺粒现象,其原因A. 缺乏水分B. 缺乏阳光C. 缺乏肥料D. 传粉不足【答案】D【解析】异花传粉往往容易受到环境条件的限制,得不到传粉的机会,如风媒传粉没有风,虫媒传粉因风大或气温低,而缺少足够昆虫飞出活动传粉等,从而降低传粉和受精的机会,影响到果实和种子的产量。

因此我们在吃玉米果穗时,常会发现有缺粒现象,其原因主要是传粉不足。

点睛:玉米的果穗常有缺粒现象,向日葵的子粒常有空瘪的,最大的可能是传粉不足也就是由于植物开花时,由于受外界因素的干扰,柱头没有接受到花粉而导致的。

4. 描述花生果实的谚语中所说“麻屋子”、“红帐子”、“白胖子”依次指的是A. 果皮、种皮、胚B. 果皮、种子、胚C. 子房、种子、胚D. 果实、种皮、胚【答案】A【解析】描述花生果实的谚语中所说“麻屋子”、“红帐子”、“白胖子”中,麻屋子是指果皮,是由子房壁发育而成,红帐子是种皮,是由胚珠的珠被发育而成的,白胖子指的是胚,是由胚珠里面的受精卵发育而成。

5. 在花的结构中,最主要的部分是A. 花柄B. 花被C. 花托D. 花蕊【答案】D【解析】试题分析:由于花蕊与果实和种子的形成有直接关系,所以,一朵花的最主要的部分是雄蕊和雌蕊(合称花蕊)。

山东省菏泽市郓城县随官屯镇中学2017-2018学年八年级上学期生物12月月考试题(解析版)

山东省菏泽市郓城县随官屯镇中学2017-2018学年八年级上学期生物12月月考试卷一、选择题1. 亲代的许多性状之所以在子代身上体现,原因是()A. 精子和卵细胞中携带着亲代的性状B. 精子和卵细胞中携带着控制性状的基因C. 总在一起生活,长相就会相像D. 父母所有的性状都遗传给了子代【答案】B【解析】生物体的各种性状都是由基因控制的,性状的遗传实质上是亲代通过生殖细胞把基因传递给了子代,在有性生殖过程中,精子与卵细胞就是基因在亲子代间传递的桥梁.如图:故选B.2. 下列关于染色体的叙述中,正确的是()A. 染色体是生物的主要遗传物质B. 每种生物的细胞内染色体的形态和数目都是一定的C. 生物体内的染色体数目只要变化不大,就不会导致严重的遗传病D. 每条染色体上都有许多个DNA分子【答案】B【解析】DNA是生物的主要遗传物质,呈双螺旋结构,A错误;每一种生物细胞内的染色体的形态和数目都是一定的,不同种生物细胞内的染色体的形态和数目不同,B正确;人的体细胞中,多了或者少了一条染色体,可能导致严重的遗传病,C错误;一条染色体上包含一个DNA分子,一个DNA分子上包含有多个基因,D错误。

3. 下列能正确反映所列各概念间关系的是()A. B.C. D.【答案】A【解析】考点:染色体、DNA和基因的关系。

分析:遗传信息载体的结构层次由简到繁的顺序:基因→DNA→染色体→细胞核→细胞。

解答:细胞核是遗传信息库,是细胞的控制中心;染色体是细胞核中容易被碱性染料染成深色的物质,染色体是由DNA和蛋白质两种物质组成;DNA是遗传信息的载体,主要存在于细胞核中,DNA分子为双螺旋结构,像螺旋形的梯子;DNA上决定生物性状的小单位,叫基因。

基因决定生物的性状。

一条染色体有一个DNA分子组成,一个DNA分子上有许多个基因。

因此,细胞、细胞核、染色体、DNA、基因大小关系如图:故选:A4. 20世纪90年代,我国科学家通过转基因技术将细菌的抗虫基因成功地转移到棉花的受精卵中,培育出抗虫效果明显的棉花新品种.以上事实说明()A. 细胞中的基因具有显性与隐性之分B. 生物的性状由基因控制C. 基因存在于染色体上D. 细胞中的基因是成对存在的【答案】B【解析】试题分析:将细菌的抗虫基因转移到棉花的受精卵中,由于棉花体内具有细菌的抗虫基因,抗虫效果明显。

People didn’t have modern machines. Life today has brou ght new problems. One of the biggest is pollution. Water pollution has made our rivers and lakes dirty. It kills our fish and pollutes our drinking water, noise pollution makes us talk louder and become angry more easily. Air pollution is the most serious kind of pollution. It’s bad to all living things in the world.Polluted air from cars, planes and factories is to thick that it is like a quilt(被子)over a city. This kind of quilt is called smog(烟雾). Many countries are making rules to fight pollution. Factories must now clean their water before it is thrown away. And they mustn’t blow dirty smoke into the air. We need to do many other things. We can put waste things in the dustbin and not throw it on the ground. We can go to work by bus or with our friends in the same car, if there are fewer people driving, there will be less pollution.Rules are not enough, every person must help to fight pollution.( )6.

From the passage we know that ____.A. a few years ago, there was no smog at allB. today people don’t have to talk to each other in a loud voiceC. we can drink water from the polluted rivers and lakesD. people are making rules in order to fight pollutionC.Do you know why different animals or pests(昆虫)have their special c olors? Colors in them seem to be used mainly to protect themselves.Some birds like eating locusts(蝗虫), but birds cannot easily catch them. Why? It is because locusts change their colors together with the change of colors of crops(庄稼). When crops are green, locusts look green. But as the harvest time comes, locusts change to the same brown color as crops have. Some other pests with different colors from plants are easily found and eaten by others. So they have to hide themselves for lives and appear only at night.If you study the animal life, you’ll find the main use of coloring is to protect themselves. Bears, lions and other animals move quietly through forests. They cannot be easily seen by hunters(猎人). This is because they have the colors much like thetrees.Have you ever noticed an even stranger act? A kind of fish in the sea can send out a kind of very black liquid(液体)when it faces danger. While the liquid spreads over(散开), its enemies(敌人)cannot find it. And it immediately swims away. So it has lived up to now though it is not strong at all.( )11. From the passage we learn that locusts _______.A. are small animalsB. are easily found by birdsC. are dangerous to their enemiesD. change their colors to protect themselves( )12. How can pests with different colors from plants keep out of danger?A. They run away quickly.B. They have the colors much like their enemies.C. They hide themselves by day and appear at night.D. They have to move quietly. ( )13. Bears and lions can keep safe because _______.A. they have the colors much like the treesB. they move quietlyC. they like brown and gray colorsD. they live in forests( )14. Why can the kind of fish live up to now?A. Because it is very strong.B. Because the liquid it sends out can help it escape from its enemiesC. Because the liquid it sends out can kill its enemies.D. Because it swims faster than any other fish.( )15. W hich is the best title for this passage?A. The Change of Colors for Animals and PestsB. Colors of Different Animals and PestsC. The Main Use of Colors for Animals and PestsD. Some Animals and Pests四、选词填空:10分much, arm, wait, see, when, spend, she, worry, have, growOnly Mother Love is true love.

八年级(下)期末物理试卷
参考答案与试题解析
一、填空题(每空1分,共14分)
1.(2分)人们常说:“宝剑锋从磨砺出,梅花香自苦寒来”.从物理学角度来理解这句话,前半句﹣﹣“宝剑锋从磨砺出”是说利用减小受力面积的方法,可以来增大压强.
考点:增大压强的方法及其应用.
专题:应用题;压强、液体的压强.
分析:根据压强的定义式p=可知,要增大压强有三种方法:一是当压力一定时,减小受力面积;二是当受力面积一定时,增大压力;三是在条件允许的情况下,可以同时增大压力,减小受力面积.
解答:解:“宝剑锋从磨砺出”是说利用减小受力面积的方法来增大压强的.
故答案为:减小受力面积;增大.
点评:很多谚语、古诗都包含一定的物理意义,要多了解这些谚语、古诗的含义,让学科知识联系更紧密.
2.(2分)一架我国自行研制的歼8Ⅱ型战斗机的质量为1.5×103kg,发动机用8×104N的推力使飞机在10s 内前进5000m,则飞机推力的功率为4×107W.为使飞机飞上蓝天,人们把飞机的机翼做成图的形状,是利用在气体中流速越大的位置压强越小(填“大”或“小”)的原理,使机翼上下表面产生压力差,从而产生升力.
考点:功率的计算;流体压强与流速的关系.
专题:计算题;简答题;气体的压强、流体压强与流速的关系;功、功率、机械效率.
分析:(1)根据功的计算公式W=Fs求出推力做的功,再根据功率的公式P=解决功率的大小;
(2)据气体流速和压强的关系,分析机翼上下方空气流速的大小判断机翼上下方气压的大小来解释飞机升力的产生.
解答:
解:(1)飞机的推力所做的功是:W=Fs=8×104N×5000m=4×108J;则功率P==
=4×107W;
(2)飞机的机翼做成如图所示的形状,在相同时间内,空气经过上方的路程长,速度大;经过下方的路程短,速度小.上方空气流速越大,压强越小;下方空气流速越小,压强越大.所以机翼下方的气压大于上方的气压,便形成向上的升力.
故答案为:4×107;小.
点评:本题主要考查功、功率的计算和流体压强与流速的关系,将力与距离对应后解决功的大小,利用功率的公式就可解决功率大小.知道流体在流速大的地方压强小,在流速小的地方压强大.
3.(4分)为保护船只的通行,打击猖狂的海盗,中国海军护航编队169舰、171舰及微山湖号补给舰于2008年12月26日下午1点从三亚出发,开赴亚丁湾.军舰在匀速驶向亚丁湾的过程中,由于消耗了燃料,则军舰所受到的浮力变小,所排开水的体积变小;其动能变小,重力势能不变(“变大”“不变”或“变小”).
考点:阿基米德原理;动能和势能的大小变化.
专题:简答题;浮力;机械能及其转化.
分析:军舰都漂浮,受到的浮力都等于军舰受到的重力;得出了受到浮力的大小关系,根据阿基米德原理分析排开水体积的大小关系.
动能的大小和物体的质量以及运动的速度快慢有关,判断动能的大小看它的质量和运动快慢是否变化就可以了;重力势能的大小和物体的质量以及所处位置的高度有关,判断重力势能是否改变,看它的质量和高度是否变化就可以了.
解答:解:Ⅱ军舰漂浮,
ⅡF浮=G,
Ⅱ军舰在匀速驶向亚丁湾的过程中,由于消耗了燃料,军舰受到的重力变小;
Ⅱ军舰所受到的浮力变小;
根据F浮=ρ液gv排可知:排开水的体积将变小.
Ⅱ军舰在匀速行驶,且军舰受到的重力变小,质量减小;
Ⅱ其动能变小;
Ⅱ军舰始终漂浮在水面上,重力势能为零,Ⅱ在匀速行驶重力势能不变.
故答案为:变小;变小;变小;不变.
点评:本题考查物体漂浮条件和阿基米德原理的应用,解决此题型的关键是知道军舰一定是处于漂浮状态.掌握动能、重力势能的影响因素,理解重力势能和动能的转化可从高度和速度来理解,可以帮助我们更好的理解能量的转化.
4.(4分)图中,甲、乙两容器中盛满水,置于水平桌面上,两容器的容积相同,形状互为倒置则两容器对水平桌面的压力相比较F甲=F乙,对桌面的压强相比较P甲<P乙,水对容器底部的压强相比较P ′=P乙′,水对容器底部的压力相比较F甲′>F乙′.(填“>”“=”或“<”)

考点:压强的大小及其计算;液体的压强的计算.
专题:推理法.
分析:因容器倒置后,液面深度不变,由液体压强公式p=ρgh可得液体对容器底部的压强变化情况,再由F=Ps可得水对容器底部压力的变化;
由容器质量不变,则可知容器对水平面的压力不变,受力面积减小,则由压强公式可得容器对水平面的压强.
解答:解:由题知,水的质量不变,容器和水的总重不变,
Ⅱ在水平面上,F=G,
Ⅱ容器对水平面的压力不变,即F甲=F乙;
Ⅱp=,倒置后底面积减小,
Ⅱ容器对水平面的压强增大,即P甲<P乙;
Ⅱp=ρgh,将容器倒置后,液面深度不变,
Ⅱ水对容器底部的压强不变,即P甲′=P乙′;。
