Explanation:
The 47,XXY karyotype of Klinefelter syndrome spontaneously arises when paired X chromosomes fail to separate (nondisjunction in stage I or II of meiosis, during oogenesis or spermatogenesis
Embryologist study embryos because Embryology is central to evolutionary developmental biology ("evo-devo"), which studies the genetic control of the development process (e.g. morphogens), its link to cell signalling, its roles in certain diseases and mutations, and its links to stem cell research.
I believe the answer is true because we spill liquids during these events causing more erosion
The sequence and number of amino acids is different (each protein has a unique sequence and arrangement of amino acids).
Phase change is the change in state. i.e. water to steam or ice to water
