如图所示，折成不同形状的四个导线框质量相等、匝数相同，高度相同，MN边长度相等，将它们用相同的细线悬挂在空中，四个导线框的下边处在同一水平线上，且四个线框的下半部分都处在与线框平面垂直的同一匀强磁场中，磁场的上边界水平（如图中虚线所示），四个导线框中都通有顺时针方向、电流强度相同的电流，均处于平衡状态．若使磁场缓慢变强，细线最不易拉断的是（   ）

如图，在载玻片两端各滴一滴草履虫培养液，使两端液滴连通．在右侧培养液的边缘滴一滴肉汁后，观察到草履虫纷纷从左侧培养液转移到右侧培养液．根据生物的特征分析，这一现象说明生物能（  ）

    I'm a junior high school student. My name is Sarah. I have a pretty aunt. Her name is Jenny. She is an actress. She must be at least thirty-five years old.
