Each kernel of corn on a single ear can inherit a different set of alleles from those inherited by other kernels. this characteristic makes corn a useful example of which law or principle?
principle of dominance
law of independent assortment
law of segregation
law of genetics

The right option is; law of independent assortment

This characteristic makes corn a useful example of law of independent assortment. The law of independent assortment is a law of heredity that was discovered by a monk named Gregor Mendel in the 1860s. This law states that sets of allele for a trait separate during the formation of gametes i.e. traits are transferred to offspring independently (singly) of one another.

the real answer is:

law of independent assortment.

b. lithosphere, asthenosphere, mesosphere   is the answer most likely

before, trains worked using the steam engine. thus, it uses heat so it is crucial to apply heat balance. the steam engine absorbs energy during the stage of boiling water. so, this is the endothermic reaction. when the steam is used to work the piston, it has to release this energy through running the train. the excess energy is released as an exhaust to the chimney. this is the exothermic process because it releases energy to the surroundings.
