Comparisons of neanderthal dna revealed that there are more similarities to non-african dna than reference sequences from west africans. Additionally, scientists found that neanderthal dna is as closely related to east asians as to europeans. This indicates that interbreeding occurred before human migration further east. What process of population genetics generated these results?.

amber has allowed scientists to study dna that has been preserved over millions of years.

the correct answer is ( hypoglycemia ); good luck

explanation:

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.

c. heat from the poles back down towards the equator.
