你负责为公司的所有电脑安装WindowsXP专业版。你预先安装了一台电脑，在这台电脑上你使用安装管理配置Sysprep应答文件。你用软盘上的文件包在这台电脑上创建了一个磁盘镜像，然后重启。通常，在WindowsXP专业版安装，电脑进入Windows的欢迎向导，要求你输入一些安装信息。由于你要配置大量的电脑，不可能对每台机器都输入安装信息，所以你要确保你创建的磁盘映像能应用，而不用你每次都输入安装信息进行人机交互，你将如何做？（）

在新机器上使用基于网络的RIS服务器应用磁盘映像

在测试机器上运行Sysprep—factory命令，使用第三方软件创建磁盘映象

使用安装管理器配置Sysprep应答文件。当磁盘映象被应用后，插入软盘，将应答文件拷贝到软盘上

创建一个Unattend.txt应答文件。将文件拷贝到C:///Winnt/System32目录下，运行Sysprep工具并且使用第三方软件重新创建磁盘映像

【多选题】How do the motor proteins kinesins and dyneins work?

The kinesins generally move toward the plus end of a microtubule (outward from the cell body); the dyneins move toward the minus end. Kinesins and cytoplasmic dyneins are generally dimers that have two globular ATP-binding heads and a single tail.

The heads of kinesin and cytoplasmic dynein interact with microtubules in a stereospecific manner, so that the motor protein will attach to a microtubule in only one direction.

The tail of a motor protein generally binds stably to some cell component, such as a vesicle or an organelle, and thereby determines the type of cargo that the motor protein can transport. Each of kinesins is thought to transport a specific set of vesicles, organelles, or molecules. In some cases, the tail of the kinesin binds directly to the cargo, while in other cases, different adaptor proteins allow the same type of kinesin to carry different cargos. Transport toward the minus end is mediated by cytoplasmic dynein, which generally uses adaptor proteins to interact with its selected cargo.

The globular heads of kinesin and dynein are enzymes with ATP-hydrolyzing (ATPase) activity. This reaction provides the energy for driving a directed series of conformational changes in the head that enable the motor protein to move along the microtubule by a cycle of binding, release, and rebinding to the microtubule. ATP hydrolysis and phosphate release by the rear motor head loosens its attachment to the microtubule. ADP release and ATP binding by the front motor head then cause a dramatic conformational change that flips the rear motor head to the front, thereby completing a single step.
