  • 在海豹和抹香鲸等深潜高手的肌肉中,肌红蛋白的含量都格外高。肌红蛋白是一种将血液中的氧吸收并储存起来的蛋白质,它为肌肉提供以后可使用的能量。因此,它们的肌肉在不需要进行呼吸的情况下还能坚持长时间的工作。此外,为了节约能量,在下潜时它们还具有降低心率的神奇本领。在美国的加利福尼亚大学,两组科研人员得出的结论颇为接近。7头小海象在陆地上的平均心跳为每分钟107次,当它们在海水中下潜时,心跳下降到每分钟39次,下降了64%。在它们潜水的初期,心率一般急剧降低,随着它们下潜的深度不断加大,心率随之缓慢下降,极限记录是每分钟3次。
    根据上述文段,下列说法不正确的是:
    A.像海豹和抹香鲸那样的深海潜水动物体内肌红蛋白的含量,明显高于一般的动物
    B.肌红蛋白是一种蛋白质,它能将血液中的氧吸收并储存起来,可以让肌肉在无法呼吸的情况下还能坚持长时间的工作
    C.深潜高手在下潜时具有降低心率的本领,这样可以节约能量
    D.研究表明,7头小海象在海水中下潜时,心率不断缓慢下降,可以由每分钟107次下降到每分钟3次
