A species of organism has survived in a mild environment for thousands for years. Suddenly, the climate changes and the area becomes a cold and barren tundra. Which of the following traits might help the species survive? A) short neck to help keep heat inside the body

B) thick fur to keep the organism warm

C) small size so the organism requires less food

D) all of the above

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

genetic variation will increase because of a new habitat and food source.
