小静饲养黄粉虫作为观赏小鸟的饲料，黄粉虫原是粮仓中的有害昆虫．她在饲养中发现，铺在养虫盒子里的泡沫塑料上有细小的噬咬痕迹，是黄粉虫会吃泡沫塑料吗？

实验一：她把黄粉虫分为两组进行喂养，甲组只喂麦麸和菜叶，乙组加喂塑料餐盒片．发现黄粉虫确实会吃塑料餐盒．

实验二：她又对塑料餐盒片和乙组黄粉虫的粪便做了实验，现象如下：

（1）黄粉虫在分类上属于______（填“脊椎动物”或“无脊椎动物”）；

（2）实验一的假设是______；

（3）实验二的现象说明______．

UML-based tools are often used for J2EE/.NET application analysis and design, both because UML’s object orientation is ideal for the J2EE/.NET implementation (66) and because of the expanding scope and complexity of today’s enterprise endeavors. (67) the approaches diverge at the coding/implementation phase, a common set of analysis and design techniques applies to both J2EE and.NET.
The use of a virtual machine (VM) architecture is also common to J2EE and .NET. Application development tools (68) intermediate-level code instead of platform-specific binary code, which means the VM interprets that code in real time or performs Just-In-Time (JIT) compilation; the Microsoft VM always runs JIT-compiled code. This VM-based model results in (69) -independent applications and is conducive to the late-binding technique that’s (70) to the OO approach.
