Select the correct order of replication of viruses

Viruses are predominantly made out of

Viruses can multiply by asexual and sexual reproduction

Why are viruses not classed as living organisms

In order to survive, pathogens require a source of nutrients, protection from harmful elements and:

Some enveloped viruses use antigenic variation which makes it difficult for the immune system to recognise different strains of the virus. Which type of antigenic variation results in a major change in spike proteins due to gene reassortment?

Which pathogen type is always a member of the normal microbiota and only causes disease in an immunocompromised host?

Which type of pathogen is an environmental microbe that is able to cause disease in an otherwise healthy individual?

Virulence factors can be described as:

What kind of virulence factors are proteases, nucleases, phospholipases and glycohydrolases?

Which of these virulence factors act as adhesins?

Which of these virulence factors assist in promoting colonization of the host?

Which of these virulence factors enable damage to be caused to the host?
