Verified step by step guidance1
Understand the structure of the SARS-CoV-2 virus: It is an enveloped virus, meaning it has an outer lipid bilayer.
Recognize the shape of the SARS-CoV-2 virus: It is icosahedral, which is a round shape, not complex or helical.
Differentiate between 'enveloped' and 'naked' viruses: Enveloped viruses have a lipid bilayer, while naked viruses do not.
Analyze the options given: Identify which options correctly describe the SARS-CoV-2 virus as round and enveloped.
Select the correct option based on the characteristics: The SARS-CoV-2 virus is round in shape with an outer lipid bilayer.
