Asponge 1cm in diameter and 10 cm tall can move 22.5 l of water through its body each day. what volume of water will it pump through its body in i h? in 1 min?

The part of the question about the size of the sponge is just there to trick you; you don't need it.  All you need is the 22.5 L per day.

To find the amount of water it can pump in 1 hour, you divide the 22.5 by 24 because there are 24 hours in a day:



Now that we have hours, we can divide that by 60 to get the amount pumped per minute (because there are 60 minutes in an hour):

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.
