COMMUNICABLE DISEASES
What is a communicable disease?
A disease that can be transmitted from one organism to another.
Are bacteria prokaryotic or eukaryotic organisms?
Prokaryotic.
Are fungi classified as prokaryotes or eukaryotes?
Eukaryotes.
Are protists generally classified as prokaryotic or eukaryotic organisms?
Eukaryotic.
Why are viruses considered non-living?
- Not made of cells
- cannot replicate on its own without a host
Name one way a communicable disease can be transmitted from one person to another.
Direct contact, droplets, contaminated food or water, bodily fluids, or vectors.
How do bacteria commonly reproduce?
Binary fission / Cloning themselves (splitting into two)
Give one example of a fungal disease that can affect humans.
Athlete's foot, ringworm, or thrush.
Name one human disease caused by a protist.
Malaria.
Give an example of a Virus?
Influenza, HIV, Hepatitis, Rhinovirus, Corona-Virus, HPV,
What is the KEY difference between a communicable and non-communicable disease.
A communicable disease can be transmitted between organisms, while a non-communicable disease cannot be transmitted between organisms.
How would you commonly treat a bacterial infection?
Antibiotics
What is an effective treatment against Fungi?
fungicides / anti-fungals
Name three effective measures against mosquito bites
- Full body clothing
- pesticides
- mosquito nets
How does a virus replicate itself?
By infecting a host's cells
A student catches influenza after sitting next to an infected person who is coughing. What is the most likely mode of transmission
Airborne Droplet transmission.
What is a concern when over-prescribing antibiotics to a pateint?
antibiotic-resistance
What environmental conditions can increase fungal growth?
Warm and Moist
What is the term we use to describe an organism that can transfer a disease from one organism to another?
Vector

When creating a drinking water system name a factor that needs to be considered to ensure the water is safe to drink
- treated with chemicals
- flowing water / does not stagnate
- not next to a waste water / sewage systems
Name three components of a bacterial cell
Cell Wall
cell Membrane
Cytoplasm
'free' DNA
Ribosomes
Plasmids
Flagella
Pili
What are the thread-like structures that make up the body of many fungi called?
Hyphae / Mycelium
Why are protists difficult to treat?
Because they are unique organisms, each with diverse cellular structures - each requires individualised treatment plans
Why do some viruses require yearly or repeated vaccinations?
They mutate frequently, or they produce a low antibody response
