Did you change her banana bag?

你换了她电解质补充液吗? 停用镁 开始使用针对严重贫血症铁糖苷？

In fact, as naturalists have ventured to observe, " dextrality" is a well–known law of nature.

事实上，正如博物学家大胆观察到那，“”是众所周知自然法则。

And yet the chemistry of these building block units, amino acids and nucleobases is the same for left and right handed.

然而，这些构建生命基础单元——氨基酸和核苷酸化学性质，论是左还是，都是相同。

They're right–handed with only rare exceptions, and when by chance a shell's spiral is left–handed, collectors will pay its weight in gold for it.

除了极少数例外， 它们都是，当碰巧螺是左时，收藏家会花上同等重量黄金来买它。

In most cases, when it comes to that left-hand versus right-hand thing, The molecule cannot just easily go from the left-hand version to the right-hand version.

在大多数情况下， 当涉及到左和问题时，分子不能轻易地从左形式转变为形式。

This isn't good, and this situation is actually called complete TGA, or sometimes dextro-TGA or d-TGA, dextro meaning " right" , since in this case, the aorta's in front of and primarily to the right of the pulmonary artery.

这种情况不太妙，被称为完全TGA，有时也叫TGA或者d-TGA，dextro意思是，因为这种情况下，主动脉在肺动脉前面并且主要在肺动脉边。

Now, one example of a shape that would resonate differently with left-handed and right-handed circularly polarized light would be a helix, and in fact, people will use a helical antenna when they want to pick up on radio waves with just one-handedness.

现在，一个例子就是螺形， 它会以不同方式与左和圆偏振光发生共振。事实上，当人们想要接收单一手性线电波时， 他们会使用螺天线。
