1.讲海龟靠甚么导航。

一开始说不可能是星星，因为海龟眼神不好。也不可能是气味，因为在过程中有气味干扰但是海龟依然能找对方向。接下来一个实验证明磁场也不可能。但是有一个结论是海龟可能是用netbine几种方法，在靠近目的地是味道是有用的(这里有题)。最后一种解释，是海龟体内的一种DNA，它能记录海龟被孵化出的地点(也就是他们去的地方”并且由母海龟遗传给小海龟。最后说有一个例子可以证明：从前在加勒比海的一个地方有很多绿海龟，但是后来捕杀很严重海龟们就不去了;近几年虽然又保护起来了但是海龟们来得仍然很少。

光线和温度是影响水草分布的主要因素光线对红藻褐藻和绿藻的垂直分布(有提问到哪种颜色最接近水面)还有内外大陆棚的分布温度主要讲了在热带海域和高纬度地区的不同还说过在high tide and low tide 区域高的温度也能提高水藻死亡率(morality)
