Why would researchers want to have both genomic libraries and cDNA libraries from a particular
organism?
a. The genomic library is generally too big to be helpful; a cDNA library, being smaller, is
much easier to study.
b. A cDNA library will be the same in every cell; the genomic library tells researchers which
genes are being expressed in individual cell types.
c. The cDNA library helps us understand how retroviruses work; the genomic library does
not.
d. The cDNA library is a lot easier to clone than a genomic library.
e. A genomic library will be the same in every cell; the cDNA library tells researchers which
genes are being expressed in individual cell types.

Which of the following statements best describes the effect of climate on biome distribution?
A) Average annual temperature and precipitation are sufficient to predict which biome will be found in an area. B) Seasonal fluctuation of temperature is not a limiting factor in biome distribution if areas have the same annual temperature and precipitation means. C) The average climate and pattern of climate are important in determining biome distribution. D) Temperate forests and grasslands are different biomes because they receive a different quality and quantity of sunlight, even though they have essentially the same annual temperature and precipitation. E) Correlation of climate with biome distribution is sufficient to determine the cause of biome patterns.
