1、那颗行星,从地球上看,它永远在太阳的背面,说明它与地球运动周期相同,所以根据公式T=2π/w可知角速度相同,根据开普勒第三定律可知围绕同一恒星运动的两颗行星周期相同则运动半径相同,
所以ACD对.
2、B项可能不会造成实验误差,因为如果恰好达到滴定终点读数,就没有误差.
但是事实上,可能是没到滴定终点,反应还在缓慢进行,而指示剂显示滴定终点的情况,所以可能读不准.
标准是,达到滴定终点,且半分钟无变化.
A项一定有误差,因为Ba(OH)2 和H2SO4发生复分解反应,产生了沉淀,为放热反应,所以会影响实验结果,造成误差.

我是耗耗 共回答了27个问题 | 采纳率100%
答案:B.
翻译:--要是(当时)交通没那么拥挤,我早在六点钟前就回来了.--多可惜/遗憾啊!蒂娜来这儿看你了.
解释:此题关键在于对首句虚拟语气的理解.
1. 首句采用了虚拟语气,即对过去事实的相反描述,这样可以将其改写并理解成:
The traffic was so heavy that I wasn't back by 6 o'clock.
交通是如此的拥挤,以至于我六点前没赶回来.
2. 而答句中的Tina be here to see you这个动作应该是和首句同时发生在过去的,但无法判断这两个动作是否存在先后关系,所以答语只能使用一般过去时.
3. 答案A为一般现在时,C为过去完成时,D为过去将来时,都有误.
答案B为正解.
另:此题貌似是高考真题,建议楼主搜索一下并确定最终答案.

主旨题的考查功能是对全文信息的理解,因为我们要找的信息也就是文章的信息要出现的地方~
主要有以下两种方法:
1 在议论文和说明文当中,首段(尤其是转折后)-每段首句-最后一段(若较长就首尾句)是文章的中心论点和各分论点的出处,因此如果碰到主旨题就需要关注这几个地方,主要任务:找出文章的中心句和关键词~!这样就基本能解题了
2 如果有一些选项比较模糊的话不妨试试“倒推”法,即从选项本身去构建文章内容,如果和原文比较接近的,作为正确选项的概率就要大
3 也可关注其他细节题的主要信息,串在一起就是文章的主要内容,即文章主旨

甲入选的概率:对对对、对对错、对错对、错对对.会6题,不会4题.
对对对概率:6/10(第一题会的概率)*5/9(第二题会的概率此时只剩九道题可选会6题已经答完一题)*4/8=1/6
对对错概率:6/10*5/9*4/8=1/6
对错对概率:6/10*4/9*5/8=1/6
错对对概率:4/10*6/9*5/8=1/6
所以甲入选的概率为:1/6+1/6+1/6+1/6=2/3
按此方法乙入选的概率为:14/15
至少有一人入选情况为甲乙、甲、乙.
都入选:2/3*14/15=28/45
仅甲入选:2/3*1/15=2/45
仅乙入选:14/15*1/3=14/45
至少有一人入选的概率为:28/45+2/45+14/45=44/45

原核生物与真核生物的主要区别是A,有无染色体B,有无细胞核C,有无细胞器D,有无细胞壁这是一道单选题
hgh_w1年前4
七曜念林一百年 共回答了11个问题 | 采纳率100%
B,有无细胞核
真核细胞与原核细胞的主要区别是:
①真核细胞具有由染色体、核仁、核液、双层核膜等构成的细胞核,
原核细胞无核膜、核仁,故无真正的细胞核,仅有由核酸集中组成的拟核.
②真核细胞的转录在细胞核中进行,蛋白质的合成在细胞质中进行,而原核细胞的转录与蛋白质的合成交联在一起进行.
③真核细胞有内质网、高尔基体、溶酶体、液泡等细胞器,原核细胞没有.
④真核生物中除某些低等类群(如甲藻等)的细胞以外,染色体上都有5种或4种组蛋白与DNA结合,形成核小体 ;而在原核生物则无.
⑤真核细胞在细胞周期中有专门的DNA复制期(S期);原核细胞则没有,其DNA复制常是连续进行的.
⑥真核细胞的有丝分裂是原核细胞所没有的.
⑦真核细胞有发达的微管系统,其鞭毛(纤毛)、中心粒、纺锤体等都与微管有关,原核生物则否.
⑧真核细胞有由肌动、肌球蛋白等构成的微纤维系统,后者与胞质环流、吞噬作用等密切相关;而原核生物却没有这种系统,因而也没有胞质环流和吞噬作用.
⑨真核细胞的核糖体为80S型,原核生物的为70S型,两者在化学组成和形态结构上都有明显的区别.
⑩真核细胞含有的线粒体,为双层被膜所包裹,有自己特有的基因组、核酸合成系统与蛋白质合成系统,其内膜上有与氧化磷酸化相关的电子传递链.
11真核生物细胞较大,一般10~100纳米,原核生物细胞较小,大约1~10纳米.
12真核生物一般含有细胞器(线粒体和叶绿体等),原核生物的细胞器没有膜包裹.
13真核生物新陈代谢为需氧代谢(除了amitochondriats),原核生物新陈代谢类型多种多样.
14真核生物细胞壁由纤维素或几丁质组成,动物没有细胞壁,原核生物真细菌中为肽聚糖.
15真核生物动植物中为有性的减数分裂式的受精、有丝分裂,
原核生物通过一分为二或出芽生殖、裂变.
16真核生物遗传重组为减数分裂过程中的重组,原核生物为单向的基因传递.
17真核生物鞭毛为卷曲式,主要由微管蛋白组成,原核生物鞭毛为旋转式,由鞭毛蛋白组成.
18真核生物通过线粒体进行呼吸作用,原核生物通过膜进行呼吸作用.
  原核细胞功能上与线粒体相当的结构是质膜和由质膜内褶形成的结构,但后者既没有自己特有的基因组,也没有自己特有的合成系统.真核生物的植物含有叶绿体,它们亦为双层膜所包裹,也有自己特有的基因组和合成系统.与光合磷酸化相关的电子传递系统位于由叶绿体的内膜内褶形成的片层上.原核生物中的蓝细菌和光合细菌,虽然也具有进行光合作用的膜结构,称之为类囊体,散布于细胞质中,未被双层膜包裹,不形成叶绿体.
  最原始的真核生物的直接祖先很可能是一种异常巨大的原核生物,体内具有由质膜内褶而成的象内质网那样的内膜系统和原始的微纤维系统,能够作变形运动和吞噬.以后内膜系统的一部分包围了染色质,于是就形成了最原始的细胞核.内膜系统的其他部分则分别发展为高尔基体、溶酶体等细胞器.按照美国学者L.马古利斯等重新提出的“内共生说”(见细胞起源),线粒体起源于胞内共生的能进行氧化磷酸化的真细菌,而叶绿体则起源于胞内共生的能进行光合作用的蓝细菌.

D.当照射光的频率v大于v0时,若v增大一倍,则光电子的最大初动能也增大一倍
tjdlx1年前2
bluecat320 共回答了15个问题 | 采纳率86.7%
答案 A 正确 只有入射光的频率大于极限频率,不管其光强如何都能产生光电效应
答案 B 也正确 极限频率v0所对应的光子能量正好等于逸出功,所以当频率为2v0时,一部分能量用于克服逸出功,剩下的能量hv0转化为光电子的最大初动能
C、D错误 C中逸出功是金属本身的属性,不会变化的;D中,光电子的最大初动能等于入射光子的能量hv减去逸出功,所以光电子的最大初动能与照射光的频率v不成正比关系

第七题错了.大概可以理解成时代上保持一致吧,表拥有这种状态性的似乎多用一般时.第二题也是这样,用了一般过去时并没有用完成时.再回到完成时的概念,它主要是强调已经完成,以及与过去某个时间或现在相对应相参照 ,可能这里没强点这两点吧.

2.D 逗号前面是一句话(有完整的主谓宾),那么后面必定是从句.which用来表示逗号前面提到的hill.
3.D 逗号前后都是完整的句子,那么就要用as.用which的话,一般都用在逗号后面;B和C没有这种用法,要用也是这么用 It was natural that he married Mary.
4.B 不看句中的 “_____ an engineer”,原句的结构还是完整的,说明需要填写的部分是个从句.既然是从句,用one of whom.而只有一个人,所以用was.

D that,that,首先The reason____he gave 是定语从句,reason在从句中做宾语,所以用that而不用why.而后句是表语从句,引导词只能用that.句型为the reason is that.
A what;which.what it was,what做was的宾语,后句是which引导的非限定性定语从句

煤干馏过程中得到的黑褐色黏稠产物,按焦化温度不同所得焦油可分为高温焦油、中温焦油和低温焦油. 脱色前是黑色,脱色后是金黄色
煤焦油中存在着硫氰化合物因他的气味对人们的正常生活及健康状态带来了极大的危害,因此必须进行脱色处理
一是利用引发氧化加速反应;二是利用试剂吸取硫氰化合物达到脱色除臭的目的;当进行了以上工艺后,颜色油黑色变为金黄色异味彻底消失.对于有条件蒸馏的用户,也可以在蒸馏的同时吸取硫氰化合物,这样即达到了脱色又除掉了异味,保证了煤焦油脱色的稳定性.

象征手法是根据事物之间的某种联系,借助某人某物的具体形象(象征体),以表现某种抽象的概念、思想和情感.它可以使文章立意高远,含蓄深刻.恰当地运用象征手法,可以某些比较抽象的精神品质,化为具体的可以感知的形象,从而给读者留下深刻的印象,赋予文章以深意,从而给读者留下咀嚼回味的余地.

某高校设计了一个实验学科的实验考查方案:考生从6道备选题中一次性随机抽取3题,按照题目要求独立完成全部实验操作.规定:至少正确完成其中2题的便可提交通过.已知6道备选题中考生甲有4道题能正确完成,2道题不能完成.
(1)求出甲考生正确完成题数的概率分布列,并计算数学期望;
(2)若考生乙每题正确完成的概率都是[2/3],且每题正确完成与否互不影响.试从至少正确完成2题的概率分析比较两位考生的实验操作能力.

解题思路:(Ⅰ)设考生甲正确完成实验操作的题数分别为X,则 P(X=k)=
C
k
4
C
3−k
2
C
3
6
,k=1,2,3,由此求得考生甲正确完成实验操作的题数的概率分布列.
(Ⅱ)设考生乙正确完成实验操作的题数为Y,则Y+~B(3,
2
3
)
,求得P(Y≥2)的值、P(X≥2)的值,再根据P(X≥2)>P(Y≥2),得出结论.

(Ⅰ)设考生甲正确完成实验操作的题数分别为X,则 P(X=k)=

Ck4
C3−k2

C36,k=1,2,3.
所以考生甲正确完成实验操作的题数的概率分布列为:

X 1 2 3
P [1/5] [3/5] [1/5]∴EX=1×[1/5]+2×[3/5]+3×[1/5]=2.
(Ⅱ)设考生乙正确完成实验操作的题数为Y,则Y+~B(3,
2
3),所以P(Y=k)=
Ck3(
2
3)k(
1
3)3−k,k=0,1,2,3,
P(Y≥2)=
12
27+
8
27=
20
27;又P(X≥2)=
3
5+
1
5=
4
5,且P(X≥2)>P(Y≥2),
从至少正确完成2题的概率考察,甲通过的可能性大,因此甲的实验操作能力较强.

点评:
本题考点: 离散型随机变量的期望与方差;离散型随机变量及其分布列.

考点点评: 本题主要考查求离散型随机变量的分布列和数学期望的方法和步骤,属于中档题.

因为每道题该学生答对的概率为2/3
所以任选出哪三道题对结果没有影响
但三题答对2题,首先要选出答对的是哪两题,用C(3,2)
有两题正确,要乘以(2/3)*(2/3)
有一题错误,再乘以1/3
结果是C(3,2)*(2/3)*(2/3)*(1/3)=4/9

没有任何方法可以证实一个物体是在绝对静止之中.绝对静止的物体是不存在的.静止只是一个物体对于它周围的另一个参照物保持位置不变,所以也只能是绝对静止和相对运动,运动和静止是相对的.判断一个物体是在静止中还是在运动中,必须选择合适的参照物.选择的参照物不同,物体的运动状态就不同.
