Multiple choice this major site of protein synthesis has ribosomes attached to it and protects proteins within its folds from being exposed to the cell’s internal environment.

a. rough endoplasmic reticulum
b. smooth endoplasmic reticulum
c. golgi apparatus

Its a

Rough endoplasmic rectulum

Or RER.

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

i'd have to say the answer is probable the second option "the geosphere interacting with the atmosphere"
