6. If you are given a piece of white marble and a piece of white quartzite what test can
you do to determine which is which? What results will you get?

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 human body. It is an organism. It is made up of cells, tissues, organs, and organ systems," said Ms. Garcia to her students. "I can
see tissues, my skin!' said Allie. "But how do I know I am made of cells too?' The students carried out an experiment to prove to Allie
that they were indeed made of cells. Here is a photo of their lab activity. What did they do?
A) They took a piece of the skin from their fingertips and looked at the tissue using a magnifying glass.
B) They dissected their finger tips! They pulled off a piece of skin and looked at it with the dissecting scope.
C) They scraped the inside of their cheek and smeared the end of the toothpick on a glass slide. They added a drop of stain and then looked at the slide using the light microscope.
D) They scraped the inside of their cheek and smeared the end of the toothpick on a glass slide. They added a drop of stain and then they used an IPhone to take a picture of the slide to share with the class.

The answer is C. The answer is C. The scraped the inside of her cheek and smeared the toothpick on a glass slide. They added a drop of stain and then looked at the slide using the light microscope. I took the USA Test Prep
