Explanation:
Nondisjunction during sperm arrangement and formation brought about her getting no sex-chromosome from her dad and an X chromosome from her mom; she is XO.

He realized that the speed of a seismic wave depends on the density of the material the wave is moving through. Mohorovicic interpreted the acceleration of seismic waves observed within the Earth's crust as a change in composition of matter within the Earth.
