Question 3

Question 6

what are virus

Answer 6

a cellular non living particle extremely small
has a lipid envelope or a capsid
the nucleas contains nucleic acid such as rna as well as reverse transcriptase but can only multiply inside host cell as they use host cell structure to form protiens
also contains attatchment protiens which help the virus identify and attach to the host cell
