Viruses are not always classified as living cells because they cannot live independently. They rely on a host to provide all resources to live, without a host they are in a dormant, near dead like state. Therefore it has to define a virus as dead or alive as it may or may not have a host.

Which is a correct interpretation of the cladogram shown below?

nataly862011 [7]

A cladogram is an image or a diagram that shows us an evolutionary relationship between different organisms. Up at the top we find the different organisms and their names. Along the side is where we find their characteristics. Anything that is past each characteristic will have that characteristic as you move up the cladogram. This diagram also shows which organisms are most closely related to one another.

Please see the image for an example. In this example we can see that the Koalas evolved after the trout.

I hope this helps, Regards.
