Lesson Worksheet: Spread of Pathogens Biology
In this worksheet, we will practice recalling the different routes by which pathogens are spread and suggesting methods that could prevent their spread.
Q1:
Which of the following is not a way that pathogens can be spread?
- AThrough email and internet communications
- BThrough consuming contaminated water (waterborne)
- CThrough direct contact with contaminated surfaces
- DThrough the air (airborne)
- EThrough exchange of bodily fluids
Q2:
How can the spread of diseases like HIV and gonorrhea be prevented?
- ABy sterilizing drinking water
- BBy using insect repellent and mosquito nets
- CBy washing food before preparing it
- DBy using condoms during sexual intercourse
- EBy coughing or sneezing into a tissue
Q3:
Chalara ash dieback and powdery mildew are examples of plant diseases caused by fungi. How could the spread of these diseases be prevented?
- ABy planting more plants in an area affected by these diseases
- BBy spraying plants with fungicide
- CBy encouraging infected plants to reproduce
- DBy spraying plants with insecticide
- EBy leaving the plants to fight off the infection
Q4:
Ebola is a very virulent disease caused by a pathogen carried in bodily fluids. The pathogen enters the body through breaks in the skin or through mucous membranes in the eyes and mouth.
What type of pathogen causes Ebola?
- AFungi
- BBacteria
- CVirus
- DProtist
What method of transmission does the Ebola pathogen use?
- AVector transmission
- BWaterborne transmission
- CDirect transmission
- DAirborne transmission
Q5:
Which of the following is not a good example of practicing good hygiene?
- AUsing the same chopping boards for raw meat and vegetables
- BWashing hands after using the toilet
- CUsing disinfectants on surfaces in the kitchen and bathroom
- DSneezing or coughing into a tissue rather than hands
- EWashing hands when preparing food
Q6:
Colds and flu are spread by coughing and sneezing.
What type of transmission is this?
- AAirborne transmission
- BDirect contact transmission
- CVector transmission
- DWaterborne transmission
How could the spread of flu and colds be prevented?
- ASterilizing water sources
- BPracticing good hygiene
- CDestroying vectors
- DWashing contaminated food
Q7:
The beet curly top virus (BCTV) is carried and spread by insects. How could the spread of BCTV be prevented?
- ABy washing the plants with soap and water
- BBy using insecticides on crops
- CBy sterilizing water sources
- DBy planting more crops within an area affected by BCTV
- EBy spraying plants with a fungicide
Q8:
By what method of transmission is malaria spread?
- AContaminated food
- BVector transmission
- CAirborne transmission
- DWaterborne transmission
- EContaminated water
Q9:
Which of the following would not be an effective way of preventing the spread of a disease?
- AIsolating individuals that are infected with the disease
- BHaving poor sanitation systems in crowded areas
- CVaccinating children and those vulnerable to the disease
- DEnsuring that people practice good hygiene
- EDestroying vectors that may carry the disease
Q10:
