Question

1. the common viral illness called influenza (flu) spreads quickly and can cause epidemics, which are rapid outbreaks. symptoms include fever and body aches. the virus is spread most commonly through the inhalation of droplets from infected people who release them while talking, coughing, or sneezing. the average time from exposure to developing symptoms is 2 days. which of these descriptions below describe the life cycle of this virus? select two correct answers. influenza is lytic because symptoms occur quickly as the virus replicates. influenza is lysogenic because it remains dormant for months to years after exposure. influenza is lysogenic because the viral dna merges with the host dna to produce a prophage. influenza is lytic because the host cells are destroyed as the virus replicates, leading to severe symptoms. influenza has life cycle stages that could be considered both lytic and lysogenic. clear all

Explanation:

• In the lytic cycle, viruses replicate quickly within host cells, causing symptoms like those of influenza (fever, body aches) to appear rapidly (average 2 - day incubation). The host cells are destroyed as the virus replicates.
• Options about lysogenic (remaining dormant, viral DNA merging with host DNA) are incorrect for influenza as it doesn't show those characteristics. And it's not a mix of both lytic and lysogenic in a way that the option describes for this context.

Answer:

• Influenza is lytic because symptoms occur quickly as the virus replicates.
• Influenza is lytic because the host cells are destroyed as the virus replicates, leading to severe symptoms.
