Answer:
Quartzite is a metamorphic rock formed when quartz-rich sandstone or chert has been exposed to high temperatures and pressures. Such conditions fuse the quartz grains together forming a dense, hard, equigranular rock. The name quartzite implies not only a high degree of induration (hardness), but also a high quartz content. Quartzite generally comprises greater than 90% percent quartz, and some examples, containing up to 99% quartz, and are the largest and purest concentrations of silica in the Earth's crust. Although a quartz-rich sandstone can look similar to quartzite, a fresh broken surface of quartzite will show breakage across quartz grains, whereas the sandstone will break around quartz grains. Quartzite also tends to have a sugary appearance and glassy lustre. The variety of colours displayed by quartzite are a consequence of minor amounts of impurities being incorporated with the quartz during metamorphism. Although quartzite can sometimes appear superficially similar to marble, a piece of quartzite will not be able to be scratched by a metal blade, and quartzite will not fizz on contact with dilute hydrochloric acid.Explanation:
The glomerular filtrate is different from the blood because the filtrate does not contain red blood cells and plasma proteins.
Answer: The other ova become polar bodies.
Explanation: After meiosis I and II in oogenesis, there should be 4 eggs, but there aren't because the other eggs 3 eggs become these small cells called polar bodies that end up dying out through apoptosis. The reason why polar bodies are made is because they take out extra DNA that the single ovum is supposed to have.
So only 1 egg is made and the rest are polar bodies that get rid of extra DNA and then die by apoptosis.
Homogeneous mixture because it is the mixture where you cannot see the different ingredients
