Thymocytes that are not selected during Positive Selection: Group of answer choices are eliminated because of their reactivity with foreign antigens are most of the developing thymocytes and die by apoptosis in the thymic cortex are exported to the periphery, where they are phagocytosed by macrophages undergo genetic reprogramming and differentiate into a different cell type try out different beta-chains to acquire reactivity with self-MHC molecules

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

imagine a line passing through the center of earth that goes through both the north pole and the south pole. this imaginary line is called an axis. earth spins around its axis, just as a top spins around its spindle. this spinning movement is called earth's rotation. at the same time that the earth spins on its axis, it also orbits, or revolves around the sun. this movement is called revolution.
