Ecosystems with greater biodiversity have an increased stability.
true or false?
i say true. : )

Yes, this is correct!

Let's imagine two systems, one with 50 species and one with 4000. Both of them experience a draught and as a result 25 species of the first one die (that's quite likely) and 800 of the second population die out (more would not be very likely).
So the first one lost 50% of species and the second one 20% - that means that the second one, with greater biodiversity has a bigger stability:)

When a virus infects a host cell, it uses the cell's machinery to make copies of its own genetic material in a process called replication. finally, during the process of self-assembly, that protein shell and the copies of the virus's genetic material are assembled into new viruses.
