The mitochondrial dna sequences of a large extended family were analyzed and compared to a single male in the family. which of the relatives' mitochondrial dna should be a match to this person?

His sisters son

Explanation:

Mitochondrial DNA are small circular chromosomes found inside the mitochondria. They are passed exclusively from the mother to children through the egg cell therefore it is maternally inherited.

In the given question. Mitochondrial DNA of an extended family was sequenced and compared to a single male.

His sisters son will match because the person and the sister will have similar mitochondria since they have the same mother. The sister will pass it down to her son.

yes it is   dangerous

explanation:

because that foot is discusting and could get you sick

c. earths continental crust is thicker than its lithosphere.

because, the lithosphere is the outermost layer of the earth/ 100 km thick and is defined by its machanical properties.the lithosphere contains oceanic and continental crust that varies in age and thickness across locations and geologic time. the lithosphere is the coolest layer of the earth in terms of temperature. the term lithosphere should not be confused with the use of "geosphere" which is used to indicate all of earth systems, including the atmosphere, hydrosphere   and biosphere. the surface of the earth can be divided into the continental crust and the oceanic crust.   the continental crust is made mostly of granite while the oceanic crust is made of basalt. the average thickness of the continental crust is 25 miles and the average thickness of the oceanic crust is 5 miles.   three types of rock, igneous, sedimentary, and metamorphic, make up the surface of the earth. that's why 3 option is preferable.
