some viruses have an optional ENVELOPE

Question 3

are naked or enveloped viruses more fragile

Answer 3

enveloped viruses are more fragile, but they may carry proteins for immune evasion or pathogenesis

Question 4

are viruses with ICOSAHEDRAL capsids naked or enveloped

Answer 4

can be either

Question 5

are viruses with HELICAL capsids naked or enveloped

Answer 5

MUST be ENVELOPED

Question 6

immunological cloak of invisibility concept

Answer 6

enveloped viruses expose relatively few surface proteins, reducing their exposure to the immune system
