孟德尔豌豆杂交实验已知玉米籽粒黄色对红色为显性,非甜对甜为显性.纯合的黄色甜玉米与红色非甜玉米杂交得到F1,F1自交结果中黄色非甜与红色甜比例为?自交结果中与亲本相同的表现行比 The baby didn't cry any more when he saw his mother.=The baby ____ ____ ____when he saw... the baby ___ cry ___ when he saw his mother come inA.doesn't ；longerB.doesn't ；moreC.didn't ；any longer选哪个?为什么选? the baby didn't cry any longer as soon as he saw his mother改为同义句the baby _____ _______cried as The baby ___________cry_________ when he saw his mother. 婴儿___________哭_________当他看到他的母亲怎么写?哪位好心人帮帮忙 谢了 设m,n为正整数,且m≠2,如果对一切实数t,二次函数y=x2+（3-mt）x-3mt的图象与x轴的两个交点间的距离不小于|2t+n|,求m,n的值因为一元二次方程x2+（3-mt）x-3mt=0的两根分别为mt和-3,所以二次函数y=x2+（ 请帮我把“林碧莹”翻译成英文名,如李—lee,乐—lok这样的, 请问.“李锦雄”怎么翻译成英文名?姓李需要加Lee 把李生译为英文名字,李lee,生呢?把李永增译为英文名字, 请问:一个香港名字"李锦雄"翻译成英文名是什么?不要用汉语拼音,姓李需要加Lee 在孟德尔的豌豆杂交试验中为什么要去除雄蕊,我去除雌蕊不行吗?到时候再把其他花的雌蕊（花粉）撒在雄蕊上,这样不行吗? 求英文女子名字大全,名字有花的意思就像 Yolanda 是女子名,也含有紫罗兰的意思……最重要的,含有 曼陀罗的意思的名字,或含有罂粟的意思的名字谢谢 The baby didn't cry any more.(同义句） The baby didn't cry any more.改为否定句The baby ______ _______cried. “The boy didn't cry any more.”的同义句 The little boy didn't cry any more 同义句 jane asked her father ,"is there any good news for me?"(改为间接引语） 有关孟德尔的豌豆杂交实验的题下列关于遗传规律的叙述中,错误的是（ ）A出现性状分离的根本原因是等位基因的分离B纯合子和纯合子杂交,后代不一定是纯合子C纯和黄色圆粒豌豆与绿色皱 关于孟德尔的豌豆杂交实验的题在完全显性的条件下,基因型AaBbcc与aaBbCC的两个亲本进行杂交,其子代中表现型不同于双亲的个体占全部子代的（ ）A5/8 B3/8 C1 D1/4 I didn't think that,I just know you are clever and this can help you I 孟德尔豌豆杂交实验的题目!23．孟德尔根据豌豆杂交实验现象提出了超越当时时代的假说,其主要内容包括 ①生物的性状是由遗传因子决定的； ②遗传因子存在于细胞核中； ③体细胞中遗传 happy us so you make feel用这点词连成句 花的种类及其象征意义 黄颜色花的种类和朵数的含义 .is good for our health.填做运动的什么时态啊?怎么拼?急健康急! Mountain climbing is a very good sport.It is( )our health,too怎么填A look for B take care of C make of D good for请问选哪个 kfc is good for our health. L_ is good for our health.
