Answer:In most cases, people with MERRF inherit an altered mitochondrial gene from their mother, who may or may not show symptoms of the disorder. Less commonly, the disorder results from a new mutation in a mitochondrial gene and occurs in people with no family history of MERRF.
Explanation:MERRF is inherited in a mitochondrial pattern, which is also known as maternal inheritance. This pattern of inheritance applies to genes contained in mtDNA. Because egg cells, but not sperm cells, contribute mitochondria to the developing embryo, children can only inherit disorders resulting from mtDNA mutations from their mother. These disorders can appear in every generation of a family and can affect both males and females, but fathers do not pass traits associated with changes in mtDNA to their children.

Explanation:
The sun rises in the east and sets in the west each day because the earth rotates toward the east making a complete turn every 24 hours while the sun actually stays in its position at the center of our solar system. Therefore, as the earth spins clockwise, the sun reaches different parts of the earth at different times as the eastern part gets the sun rays first before it passes to the other parts of the earth.
