In most natural populations, individuals vary slightly in their genetic makeup, which is why they do not all look or act alike.

p57第一段：
Nitrogen is the atmosphere's most abundant element. The major reservoir for nitrogen is the atmosphere. Chemically unreactive nitrogen gas(N2) makes up 78% of the volume of theatmosphere. Nitrogen is a crcial component of proteins, many vitamins, and nucleic acids such as DNA. However, N2 cannot be absorbed and used directly as a nutrient by multicellular plants or animals.
氮是大氣中最豐富的元素，主要儲存於大氣中，占大氣的78%。雖然氮氣是組成蛋白質、維他命、核酸的關鍵成分，但卻不易直接被吸收利用。
