I don’t know what the options are, but remember viruses are:
-nonliving (they cannot reproduce without a host)
-surrounded by a protein coat
-composed of DNA or RNA
-able to live for years
-unable to thrive outside of the host cell
-classified into 4 structural classes (helical symmetry, isometric symmetry, enveloped, bacteriophage)
True! they are all made up of eukaryotic cells :) hope this helps!
Ever since researchers sequenced the chimp genome in 2005, they have known that humans share about 99% of our DNA with chimpanzees, making them our closest living relatives.
