Explanation:

The Earth's crust, or Lithosphere, is the Earth's solid crust, its outermost, thinner, and consolidated layer, essentially made up of rocks. The rocks are formed by a set of minerals. In them we can find glass, salt, among others.

The rocks that originate in very deep areas of the earth's crust, and their ages are, in general, very old and more complex, while the more superficial layers have younger and less complex rocks.

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
