The following statements

1. Influenza particles bud from the cell, releasing the virus into the surrounding environment

2. HA spikes attach to host cells

3. Influenza proteins are synthesized

4. Influenza enters the host cell

5. Nucleic acid is released into the host cytoplasm

6. Influenza nucleic acid is packaged in capsid

Answer:

STEP 1 => HA spikes attach to host cells

STEP 2 => Influenza enters the host cell

STEP 3 => Nucleic acid is released into the host cytoplasm

STEP 4 => Influenza proteins are synthesized

STEP 5 => Influenza nucleic acid is packaged in capsid

STEP 6 => Influenza particles bud from the cell, releasing the virus into the surrounding environment

Explanation:

When influenza gain entry into an host body, they stick to the host cells. It then hijacks the host machinery with the aim of producing more and new viral particles. The new particles then infects nearby cells causing infections. While after all the components are sybthesize, the virus leaves through budding.
