Explanation:
you have to keep heat and pressure rising on the rock, until the minerals melt. The earlier stages of this process (if it ends at that point) are called 'migmatite' (mixed rock) where the rock consists partially of unmelted metamorphic rock

Answer:
Option 3, Chromatids remain attached to one another until anaphase
Explanation:
Centromere lies at the center, end or other points of the chromosome and joins the two sister chromatids. During cell division, the spindle fibers attaches at the centromere and detaches the chromosomes during the anaphase of the cell division to ensure that each daughter cell gets equal number of chromosomes at the end of mitosis. Centromere plays an essential role in the separation of chromosomes. 
Hence, option 3 is correct

Answer:
The correct answer is "random coils".
Explanation:
Random coil is a type of polypeptide secondary structure comprised of conformation that do not follow an established conformation but rather are oriented randomly. These random coils conformations provides flexibility to proteins, since the lack of a particular structure (such as alpha helices or beta sheets), allows the protein to bend, fold or move.
