Several viruses are shown. All of them have different shaped glycoprotein projections. Why does a virus need to have these projections?
Projections help the virus move in its environment.
Projections help the virus maintain homeostasis
Projections help the virus reproduce with other viruses
Projections helps the virus attach to specific host cells
Compare the Glycoprotein projections in the virus images to the cell's cilia below. What do you think the the glycoproteins and cilia are used for?
Cilia are used for locomotion and projections are used for protection
Cilia are used for defense and projections are used for distracting predators
Projections are used for attachment and cilia are used for moving fluid surrounding the cell
Projections are used for obtaining food and cilia are used for making proteins
Which of the following statements explains what happens when a virus is able to inject viral material into a living animal cell?
It will carry out aerobic respiration
It will take over the cell's metabolism / Mechanism/ machinery and assemble new viruses.
It will reproduce both sexually and asexually
It will cause no change to the cell
Which viral replication cycle does the cell go through lysis (burst) and destroyed ?
Lysogenic
Binary Fission
Digestion
Lytic
During which replication cycle does the virus rupture through the cell membrane killing the cell?
Lytic
Lysogenic
Both
None of them
What is an important difference between a virus and a bacteria cell?
The virus is more contagious than the bacteria
The virus contains genetic information, the bacteria does not
Streptococcal and Viral Pharyngitis are the same thing
The virus cannot reproduce on its own, but the bacteria can
What do viruses have in common with all cells?
The ability to reproduce on their own
Being able to grow and divide
Having genetic material
Can preform protein synthesis
What is the one difference between a cyanobacteria and a virus?
Viruses can go through growth and development, but cyanobacteria cannot
Cyanobacteria can reproduce on their own, but viruses must use a host cell to reproduce
Cyanobacteria do not have a nucleus and viruses do have a nucleus
Viruses are much larger in size than cyanobacteria
Several viruses are shown. All of them have different shaped glycoprotein projections. Why does a virus need to have these projections?
Movement
Homeostasis
Attachment
Reproduce
Which one is the virus ?
A
B
C
D
Viruses can be transmitted through air, water, food, insect bites, and direct skin contact. Once a virus gains entry to the body, it invades a host cell in order to-
Deactivate the host cell's defenses
Access cellular machinery for replication
Metabolize host proteins and grow
Synthesize antibodies for defense
Which of the following is the characteristics for virus?
Needs a host to reproduce
Freely reproduce
Creates their own energy
Can grow and development
Influenza VirusesThe H1N1 virus is a strain of influenza that caused a worldwide pandemic outbreak in 2009. Like other influenza viruses, it causes a respiratory infection that spreads from person to person by coughing and sneezing.
If you contract the flu why is it important to take an antiviral medication (Ex: Tamiflu) within 2 days of symptom onset?
The virus is dormant in cell
The virus does not mutate
The virus replicates quickly
Lytic
The virus inactivate when enter the cell
Janie was exposed to the flu 5 days earlier when she visited her friend Sarah who tested positive 3 days before Janie. Why is it so important for the doctor to immediately prescribe an antiviral to treat the symptoms?
The flu has a lysogenic replication cycle that remains dormant for along period of time before causing any symptoms
The flu has a lytic replication cycle that replicates quickly
The flu is transmitted through a vector such as a tick that transfers the virus to other people
The flu can replicate outside of a host cell on its own
Susie attends a Taylor Swift concert with her group of friends on Saturday where they share snacks and drinks. The following Saturday Susie wakes up with a sore throat, high fever, muscle aches, and chills. Susie's mom takes her to the doctor where she tests positive for strep throat later that day. There is no vaccine for strep throat. What type of viral reproductive cycle does strep throat have?
Lytic, because of the quick onset of symptoms
Lytic, because they share food and drinks
Lysogenic, because there is no vaccine for this type of viral reproduction
Lysogenic, because of the long incubation period
