which high grade, foliated metamorphic rock has visible crystals?
Answer:
Gneiss
Explanation:
Gneiss forms at the highest pressures and temperatures and has crystals large enough to see with the unaided eye. Gneiss features minerals that have separated into bands of different colors. The bands of colors are what define foliation within gneiss.
Hope this helps! : )
Gneiss crystals are large enough to be seen without magnification. Gneiss has color-banded minerals. Color bands define gneiss foliation.
What is Gneiss?The metamorphic rock known as gneiss is quite common and can be found all over the world. It is produced when procedures of high temperature and high pressure metamorphism are applied to formations that are made up of rocks that are either igneous or sedimentary in nature.
Gneiss is formed at temperatures and pressures that are higher than those required to make schist. Gneiss almost always has a banded texture that is defined by alternating darker and lighter colored bands and does not have a clear cleavage. Gneiss may also lack a distinct cleavage.
Gneisses are frequently found in the crust of continental shields that formed in the distant past. Gneisses like the Acasta Gneiss are among the oldest rocks on Earth and are classified as Proterozoic.

Skeletal muscle exhibits alternating light and dark bands called a sarcomere
Skeletal muscle is having sarcomere having myofibrils which appear dark and light in the microscope.
What is skeletal muscle?Only thin filaments containing actin are present in isotropic bands, anisotropic bands are the darker bands (A bands).
Repeating sarcomere sections, which are visible under the microscope as alternating dark and light bands, make up myofibrils.
When a muscle contracts or relaxes, long, fibrous protein filaments called sarcomeres glide past one another. Because of this, skeletal muscle is also known as striated muscle.
Therefore in appearance due to myofibrils composed of the sarcomere look light and dark bands in the skeletal muscle under a microscope.

TRANSCRIPTION AND TRANSLATION
Genes provide information for building proteins. They don’t however directly create proteins. The production of proteins is completed through two processes: transcription and translation.
Transcription and translation take the information in DNA and use it to produce proteins. Transcription uses a strand of DNA as a template to build a molecule called RNA.
The RNA molecule is the link between DNA and the production of proteins. During translation, the RNA molecule created in the transcription process delivers information from the DNA to the protein-building machines.
DNA → RNA → Protein
DNA and RNA are similar molecules and are both built from smaller molecules called nucleotides. Proteins are made from a sequence of amino acids rather than nucleotides. Transcription and translation are the two processes that convert a sequence of nucleotides from DNA into a sequence of amino acids to build the desired protein.
These two processes are essential for life. They are found in all organisms – eukaryotic and prokaryotic. Converting genetic information into proteins has kept life in existence for billions of years.
DNA and RNA
RNA and DNA are very similar molecules. They are both nucleic acids (one of the four molecules of life), they are both built on a foundation of nucleotides and they both contain four nitrogenous bases that pair up.
A strand of DNA contains a chain of connecting nucleotides. Each nucleotide contains a sugar, and a nitrogenous base and a phosphate group. There is a total of four different nitrogenous bases in DNA: adenine (A), thymine (T), guanine (G), and cytosine (C).
A strand of DNA is almost always found bonded to another strand of DNA in a double helix. Two strands of DNA are bonded together by their nitrogenous bases. The bases form what are called ‘base pairs’ where adenine and thymine bond together and guanine and cytosine bond together.
Adenine and thymine are complementary bases and do not bond with the guanine and cytosine. Guanine and cytosine only bond with each other and not adenine or thymine.
There are a couple of key differences between the structure of DNA and RNA molecules. They contain different sugars. DNA has a deoxyribose sugar while RNA has a ribose sugar.
