Which best describes mitochondrial DNA (mtDNA)? Mitochondrial DNA is the same as nuclear DNA.
Mitochondrial DNA is inherited through the father.
Mitochondrial DNA can be traced for generations.
Mitochondrial DNA requires large amounts for testing. Which best describes mitochondrial DNA (mtDNA)?

Select all of the statements which are true. electrons are located in shells or orbits around the atom. electrons orbit slowly around the atom. electrons travel in one flat path around the nucleus of an atom. the valence of an atom is determined by the number of electrons in the atom's outermost shell.

Correct relationship between molecular formula and empirical formula

Astable electron arrangement for an atom is one that does not easily change. how is this arrangement arrived at? a. valence electrons are transferred or shared to create a full outer shell of electrons. b. valence electrons are discarded into space to create a full outer shell of electrons. c. protons (positive charge) pair with valence electrons (negative charge) to create a strong bond. d. outer shells with valence electrons are transferred or shared.
