Critics point out that biofuels use cropland that otherwise would be producing food, and the rise of the electric car could speed the decline in the use of fossil fuels, mak- ing biofuels obsolete.. In the future, perhaps agricultural scientists will be able to use these tech- niques to develop crop plants that can be produced, processed, and distributed with...

Selection is the process of determining which animals are to be used as breeding stock. The simplest form of selection considers only traits of the individual, whereas more complex selection takes account of ad- ditional information on relatives, such as siblings, par- ents, and offspring. This process requires reliable measures for desired traits, acquisition of records from numerous animals, and...

gon, far more abundant in Earth’s atmosphere than any of the other noble (inert) gases, is a by-product of the radioactive decay of an isotope of potassium. Earth’s sur- face, warmed by the absorption of solar radiation, conducts heat into the lowest portion of the atmo- sphere. Virtually all the phenomena that are com- monly referred to as “weather” occur...

The phenomenon was dis- covered in the eighteenth century and studied by Al- bert Einstein in the 1920’s. After the widespread adoption of silicon for circuitry in the twentieth cen- tury, photovoltaic cells became less expensive to pro- duce and more efficient...
