Total questions: 12
Worksheet time: 3hrs 0mins
Why are viruses such a threat to the human race?
because they are microscopic
they have evolved (changed over time) in such a way that makes them difficult to kill
they can only be treated with antibiotics
they attack more humans more than other species
Viruses are difficult to kill because they
only live in humans
they have the ability to rapidly evolve
they cannot be treated
mutate from one human to another
If viruses are not alive, then how do they harm the human body?
by creating new cells
by tricking a cell into changing and becoming different a kind of cell
by "hijacking" or taking over human living cells and using those cells to reproduce
by consuming cells for energy
How does a virus take over a living cell?
they send out a protein that connects like a lock and key to a cell protein which allows the virus into the cell where it can reproduce
by consuming the cell for energy
by allowing a host cell DNA to enter into the virus
by asexually reproducing in the cell
What specific cells are unlocked and invaded with with COVID-19?
muscle cells
blood cells
bones cells
lung cells
Once a virus takes over a cell, it tricks the host cell into making ____________of copies of the virus genetic material

The human body can try to fight a virus by
triggering an immune response
releasing a protein that interferes with reproduction of the virus
shutting down the cells that have been invaded
all of the above
True or False: Viruses can be transmitted from one person to another without a person knowing because they don't "feel" sick.
true
false
What is thought to be the root of the most severe coronavirus cases?
protein imbalance
high levels of glucose
an immune system failure
a cytokine storm
The extreme immune response the body has to the coronavirus can
kill off all the all viruses in the body
cause an over production of bad bacteria in the gut
cause kidney stones
worsen pneumonia and cause severe inflammation
Antiviral drugs are different from antibiotics because they
work specifically to kill certain viruses, whereas antibiotics work on many types of bacteria
are challenging to develop
also damage the host cell when targeting the viruses
all of the above
The only virus that can truly be cured by drugs is
HIV
Coronavirus
Influenza
Hepatitis C
