Answer: Volcanoes erupt when molten rock called magma rises to the surface. Magma is formed when the earth's mantle melts.

If magma is thick, gas bubbles cannot easily escape and pressure builds up as the magma rises. When the pressure is too much an explosive eruption can happen, which can be dangerous and destructive.

Why would you probably not see a volcano on the east coast of the United States?
DerKrebs [107]

D. There are no major fault lines or hot spots close by.

Why?

Because "They don’t occur anywhere else other than along the Ring of Fire" is incorrect, the Ring of Fire is just a place where many volcanoes are.

Because "The composition of the rock in that area is not conductive to eruptions." they type of rock doesn't play that much of a role in the formation of volcanoes

Because "The magma doesn’t have enough silica or gas to form an explosive eruption." It isn't a gass that is found, it is the build up of pressure from fultlines moving and things on the inside of the earth.

OverLord2011 [107]

The false statement is: (a) Transcriptional regulators usually interact with the sugar–phosphate backbone on the outside of the double helix to determine which DNA sequence to bind.

Transcriptional regulator or factor is protein with the ability to control and regulate gene expression at the transcription level by binding to DNA. Transcriptional factors have domain-DNA-binding domain which contains structural motif that recognizes DNA and it is responsible for the attachment to specific DNA sequence. It usually binds to the DNA major groove (hydrogen bonding) because it is less degenerate than that of the DNA minor groove.  

Transcriptional factors also contain trans-activating domain for the binding of other proteins and signal-sensing domain for the detection of external signals.
