have randomly arranged grains

include quartzite and marble

form from crystallized magma

Metamorphic rocks are those rocks that are modified by heat, pressure and chemical processes, that occurred on the rocks that are buried deep below the earth crust. The exposure of the rocks developing under the earth crust gets altered on the basis of the mineralogy, chemical composition of the rocks and the texture of the rocks.

The non- foliated rocks are type of metamorphic rocks, which are formed by the igenous intrusions. The minerals inside these rocks are formed by the crystallization of the magma, the atoms in these rocks are tightly packed, the external structure of the rocks do not show any kind of layering or band appearance. Therefore, the rocks exhibit randomly packed grains.

The examples of these rocks are hornfels, quartzite, marble and novaculite.

answers are:

lysogenic     viral dna merges with host cell dna

lysogenic     no symptoms

lytic               viral dna takes over

lysogenic     virus does not destroy host cell

lytic               virus destroys host cell

lytic               induces symptoms of viral infection

lysogenic       cell reproduces and spreads provirus
