  • A.在水草丰富的浅水区确定样方调查芦苇密度
  • B.用标志重捕法调查动物的活动范围和迁徙路线
  • C.定期从酵母菌培养液中取样并计数,调查其种群增长

查看答案 纠错
答案: B、C、D
本题解析:

样方调查种群密度必须随机取样,而不能在水草丰富的浅水区确定样方,故A错误;由于动物的生活范围大,所以调查动物的活动范围和迁徙路线一般用标志重捕法,故B正确;酵母菌用液体培养基来培养,培养液中的酵母菌种群的增长情况与培养液中的成分、空间、pH、温度等因素有关,所以要定期从酵母菌培养液中取样计数,调查其种群增长,故C正确;单基因遗传病的发病率相对较低,因此调查某单基因遗传病的发病率,需要在较大的样本人群中进行,故D正确。

For people who don′t read instructions

The easiest-to-use phone is the iPhone. It′sthat has pushed it to the No.1 selling position, surpassing the Motorola Razr.The iPhone′s touch screen is easy to operate and it′s also easy to customize (用户化). The iPhone can run allsorts of applications such as those help you to lose weight, identify a song onthe radio, find a restaurant or do many other things.

For the futurist

The system shouldimprove as it becomes more popular, so it holds great promise. With fewrestrictions on the design of applications for the phone,

the G1 could be the first phone toincorporate (整合) some of the coolest.

For the road warrior

The new BlackBerry Storm is something likethe equivalent (等同物) of a mullet--a business up front, party in the back. It stillincorporates the serious mail and organization features that have endeared (使受钟爱) these phones to business people. The 3.25-inch is bright anddetailed and it′s a decent size for watching videos on the go.

For the Luddite (反对技术进步的人)

For those who can′t handle buttons and newfeatures, there is the Samsung Jitterbug Dial. Some people are Luddites whojust want a few large buttons to make calls. That′s it, just calls. That makesit even easier to use an iPhone.
