科学家做过有趣的实验,他们把跳蚤放在桌上,一拍桌子,跳蚤迅即跳起,高度均在其身高的100倍以上,堪称世界上跳得最高的动物。后来,科学家在跳蚤头上罩一个玻璃罩,再让它跳,这一次跳蚤碰到了玻璃罩,连续多次后,跳蚤改变了起跳高度以适应环境。接下来,科学家逐渐改变玻璃罩的高度,跳蚤都在碰壁后主动改变自己的高度。最后,玻璃罩接近桌面,跳蚤已无法再跳了,于是,科学家把玻璃罩打开,再拍桌子,跳蚤仍然不
Scientists have done interesting experiments, they put the flea on the table, a pound the table, fleas jump up to a height of 100 times its height in more than 堪称, the world's highest skipping animals. Later, the scientist covered a flea head with a cover and let it jump, this time the flea hit the cover, and after several consecutive fleas changed the height of the take-off to suit the environment. Next, scientists gradually change the height of the glass cover, fleas in the wall after the initiative to change their own height. In the end, the glass was close to the table, and the flea was no longer able to jump, so scientists opened the glass and patted the table, and the flea still did not
