Answer:
tRNA and mRNA can leave the nucleus.
Explanation:
tRNA, when mature and correct, can leave the nucleus and enter the cytoplasm. mRNA can leave the nucleus through pores in the nuclear membrane. However, DNA cannot leave the nucleus, it has to be transcribed into RNA.
DNA evidence and the fossil record indicate are the ancestors of the living cetaceans were land-dwelling mammals. DNA evidence allows to trace the evolutionary origin of taxonomic groups.
DNA evidence refers to the linear order of nucleotides, which can be used to trace the evolutionary origin of a particular taxonomic group.
When the linear order of DNA nucleotides is conserved, it is known as sequence homology.
Fossils are preserved remains of organisms that once lived on the Earth, which can also be used as evidence to trace the evolutionary origin of a given group.

The factor that explains most of the difference in standards of living among countries around the world is PRODUCTIVITY.
One major measure that can be used to determine the standard of living of people in a particular country is the growth rate of the its Gross Domestic Product [GDP] per capita. The growth rate of GDP is a reflection of the labour productivity of that country. Labour productivity refers to the measurement of the amount of goods and services that are produced in a country by one hour of labour. An increase in productivity signifies an increase in the standard of living of the people in the country. Labour productivity differs from one country to another and this result in difference in the standard of living.
