A high metabolic rate means more energy is available to process them.

高代谢率意味着更多的能量处理信息。

They've undergone selection for a higher metabolic rate that increases heat production.

他们有更高的新陈代谢率，产生更多热量来挺过自然选择的考验。

These two traits together indicate a higher metabolic rate.

这两个特征共同表明更高的新陈代谢率。

And relative to their body size, hummingbirds have the highest metabolic rates of all vertebrates.

相对于它们的体型，蜂鸟的新陈代谢率是所有脊椎动物中最高的。

Ali says muscle has a higher metabolic rate than fat, so the more muscle you have, the more calories you burn, even when you are at rest.

阿里说肌肉的新陈代谢率比脂肪高，所以你拥有的肌肉越多， 你燃烧的卡路里就越多， 即使你在休息时也是如此。

Because they have a larger ratio of surface area to mass, small animals lose heat more quickly than larger animals, so they have higher metabolic rates and their cells wear out more quickly.

因为它们的表面积与质量之比更大，所以小动物散热比大动物更快，所以它们有更高的代谢率，而且它们的细胞累得更快。

However, this wasn't enough on its own, because he also found that the water needed to have enough oxygen in it— so these two factors seemed necessary to support the high metabolic rate of these large fish.

但是只有这一点还远远不够，因为他还发现海水中需要饱含足够的氧气，于是这两个因素一起便足够证明这些大型鱼类的高代谢率观点了。
