True of False: Viruses are living things.

• True

• False

Antibiotics are used to treat:

• viruses

• bacterial infections

• fungal infections

Which microorganisms are always harmful?

• Bacteria

• Microbes

• Pathogens

• Viruses

Viruses require a host cell to

• Breathe and eat

• Replicate

• Move and sleep

• Make protein and carbohydrates

One important way to control the spread of viruses in through

• the use of vaccines

• drinking a lot of tea

• the use of other types of bacteria

• the use of antibiotics

Vaccines are made from

• dead or weakened viruses
• fungi
• allergens
• strong, active viruses

What do all bacteria have in common?

• They all have cell nuclei.

• They're all multi-cellular organisms.

• They're all single-celled organisms.

• They can all be found inside the human body

Some bacteria move by using a long, whip-like structures called:

• tails

• cillia

• organs

• flagella

how viruses cause disease?

• They get inside the biggest cells and take it over. Viruses use the biggest cells machinery to make lots of copies, so many that the cell alive and burn other cells around it! They can make less viruses very quickly - just one virus can turn into lots of virus but they are harmful.

• They get inside the weak cells and take it over. Viruses use the weak cells machinery to make lots of copies, so many that the cell destroyed and create other cells around it! They can make more viruses very slow - just one virus can turn into little of viruses and make you die

• They get inside the host's cells and take it over. Viruses use the host cells machinery to make lots of copies, so many that the cell bursts and infects other cells around it! They can make more viruses very quickly - just one virus can turn into lots of viruses and make you sick

• They get inside the germs and take it over. Viruses use the germs machinery to make lots of copies, so many that germs bursts and infects other cells around it! They can make more viruses very fast - just one virus can turn into lots of viruses and make you sick.
