APES 8.15 - Infectious Diseases and Pathogens

Aiden, Luna, and Noah are learning about infectious diseases in their biology class. Their teacher asks, 'What are pathogens?'

• Living organisms that cause infectious diseases

• Non-living substances that cause infectious diseases

• Bacteria that cause infectious diseases

• Viruses that cause infectious diseases

Evelyn and Henry are discussing about diseases. Evelyn says that infectious diseases can be transmitted from one person to another, while non-infectious diseases cannot. Henry, on the other hand, believes that infectious diseases are caused by bacteria, while non-infectious diseases are caused by viruses. Anika, who is listening to their conversation, is confused. Can you help Anika understand the difference between infectious and non-infectious diseases?

• Infectious diseases can be transmitted, while non-infectious diseases cannot

• Infectious diseases are caused by bacteria, while non-infectious diseases are caused by viruses

• Infectious diseases are more severe than non-infectious diseases

• Infectious diseases can only be treated with antibiotics

Henry, James, and Mia are studying about infectious diseases. They learned about vectors. Can you help them understand what vectors are?

• Organisms that transmit pathogens and cause infectious diseases

• Organisms that are infected by pathogens and cause infectious diseases

• Organisms that are immune to pathogens and prevent infectious diseases

• Organisms that are carriers of non-infectious diseases

Lily, Isla, and Scarlett are studying the effects of climate change on disease vectors for their science project. They are particularly interested in understanding how the range of disease vectors is affected. What conclusion might they reach?

• They might conclude that climate change leads to an expansion of tropical climates, allowing disease vectors to survive in new areas

• They might conclude that climate change reduces the range of disease vectors, making them less prevalent

• They might conclude that climate change has no impact on the range of disease vectors

• They might conclude that climate change only affects non-infectious diseases

Anika, Grace, Lily, Jackson, Zoe, and Aiden are part of a geography project where they are studying about infectious diseases. They are focusing on a case study of a less developed nation and observed that it has higher rates of these diseases. What are some factors that contribute to this scenario in their case study?

• Less sanitary waste disposal, lower access to healthcare facilities, lack of clean water

• Higher access to healthcare facilities, lack of clean water, higher temperatures

• Higher access to antibiotics, better waste disposal systems, lower temperatures

• Higher temperatures, better waste disposal systems, higher access to antibiotics

Lily, Aria, and James are history enthusiasts and they are currently exploring the medieval period. During their study, they come across a fact about the plague that devastated Europe in the 14th century. They are curious to know which bacterial pathogen was responsible for causing the plague. Can you help them?

• Yersinia pestis

• Mycobacterium tuberculosis

• Plasmodium falciparum

• West Nile virus

Grace, Ava, William, Evelyn, Hannah, and Liam are on a field trip to a history museum. They come across an exhibit about the plague. Their guide asks, 'How is the plague transmitted to humans?'

• Through bites from fleas that live on rats

• Through direct contact with infected humans

• Through contaminated water sources

• Through respiratory droplets from infected individuals

Priya, Mason, Emma, Henry, Anika, and Luna are part of a humanitarian mission to a region where malaria is prevalent. Who among them would be most susceptible to malaria if they do not take proper precautions?

• Priya, if she is under the age of five

• Mason, if he is a teenager

• Emma, if she is over the age of 65

• Priya, if she is pregnant

James, Arjun, and Abigail are planning a trip to a tropical country for their school project. They learned that they need to take precautions against malaria. What is the main vector they should be aware of?

• Mosquitoes

• Ticks

• Fleas

• Rats

During a summer camp, Isla, Michael, and Liam were discussing the recent West Nile virus outbreak in their city. They were curious to know, how is this virus primarily transmitted to humans?

• Through bites from infected mosquitoes

• Through direct contact with infected birds

• Through contaminated food and water

• Through respiratory droplets from infected individuals
