Short answer
Explain how a viruses reproduce themselves.
Viruses reproduce themselves by anchoring themselves in a host cell and inserting their DNA into the host cell and "telling" the cell to replicate them instead. Then when the cell is to full it explodes and the little viruses go to infect other cells.
A virus that carries it's genetic material in the form of RNA
Retrovirus
All viruses have the same size and shape.
False, why
Vaccines are made from
Weakened viruses
What is the chemical symbol for water.
H2O
Measles and Mumps vaccines protect you for a lifetime. Why, then do people get the flu shot each year.
The flu virus mutates every year so the vaccine you got last time won't protect you this year.
A virus that infects Bacteria
Bacteriophage
The flu can affect both birds and mammals.
True
Scientists began to examine viruses following the invention of
The electron microscope
How many moons does Mars have?
Bonus points if you know their names

Based on what you've learned about viruses, explain why HIV is such a dangerous virus.
HIV is a dangerous virus because when your white blood cells are destroyed then you cannot fight back against any viruses and you could die from simple viruses such as the cold or flu.
The penetration of a virus or it's nucleic acids into a host cell.
Viral Infection.
The influenza viruses are dangerous because they spread easily and can mutate into different forms.
True
Viruses can reproduce in
Living things
What is the largest organ in the human body?
Skin
List three different ways in which viruses can be spread among humans. Give one example of a virus and how it spreads.
Viruses spread by infected food/drink, sexual interactions,water droplets, and touch. HIV is spread by sexual interactions.
The RNA and DNA that a cell needs to reproduce itself.
Genetic Material
Bacteriophages can be dangerous to humans.
False, Why
A viruses that infects bacteria enters cells...
by attaching its protein coat to the cell wall and injecting its genetic material through the cell wall.
In which book series would you find the character Katniss Everdeen?
The Hunger Games
Are viruses living or non-living?
Both are correct, Explain why
Organic compounds that contain genetic information and the information necessary for an organism to make the proteins it needs.
Nucleic acids
Viruses resemble other viruses more than the host cells they invade.
Flase,why
A virus that infects animals enters cells...
by being engulfed by the host cell.
