Metamorphic rocks are formed from other rock that has been subjected to very high temperature and pressure.
When one of the earth's plates comes in contact with another either by both traveling opposite directions, straight into each other, or from one slipping under the other (subduction zone), the pressure/friction of the plates against each other melts the rocks and after they cool they are metamorphic. Example is in Washington state when the Juan de fuca plate is going under the North American plate the pressure/friction of this melts the rocks which then form metmorphic rock.
Facilitated diffusion
<span>The word 'diffusion' means free movement across distance, with or without the presence of a barrier. However, there is a phenomenon known as facilitated diffusion which occurs at the cellular level. The cell does not allow free radicals and other harmful substances to enter and harm the cell organs. This is possible due to the structure of the cell membrane. The structure is such that, it allows only certain things to pass in and out of the cell. One such activity that allows selective movement in and out of the cell is the process of facilitated diffusion.</span>
A group of atoms bonded together
Answer:
Explanation:
The history protein H2A, H2B, H3 and H4 forms an octamer ( 2 each of the four histones) around which the DNA is wrapped. They help in packaging the DNA allowing for compaction of the DNA
Linker histone H1 and a length of DNA (linker DNA) links two nucleosomes together and they also play essential role in chromatin strucrure, stabilizing it and also modulating accessibility of the DNA to biological processes.
