When the environment changes, which type of organism is most likely to survive? 1) One that produces asexually and has offspring that is genetically identical
2) One that produces sexually and has offspring that are genetically different
3) One that produces sexually and has offspring that is genetically identical
4) One that produces asexually and has offspring that are genetically different

4: One that produces asexually and has offspring that are genetically different.

If the environment changes, many members of a certain species may die and so it becomes less and less likely for that species to produce sexually, so it will die out. Furthermore, if the asexual species produces the same traits, that species will not adapt to changes in the environment and will also die out.

Hope this helps ^^

substitution is the answer in this case

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
