Which of the following would be the easiest to eradicate?a) A pathogen that is common in wild animals but sometimes infects humansb) A disease that occurs exclusively in humans, always resulting in obvious symptomsc) A mild disease of humans that often results in no obvious symptomsd) A pathogen found in marine sedimentse) A pathogen that readily infects both wild animals and humans
Write short explanatory notes on how change of lifestyles and modernization contribute to the spread of diseases under the following concepts/topics:
through food production,
ability to store food longer,
increasingly domesticated animals,
increased consumption of raw foods,
the worldwide trade of agricultural products
through food production: Here you should focus on how modern processes contribute to the spread of diseases. For example, Modern processes involved in food production increase the risk of food contamination with pathogenic microorganisms. This can come from machinery used for food processing or food handlers. The answer given should have sufficient points for marks allocated. Your explanations can be supported by examples of microorganisms or diseases.
ability to store food longer: growth of microorganisms in food stored for extended period. Consider factors such as temperature fluctuation, poor packaging etc.
increasingly domesticated animals: How an increase in…
What is the main reason that infectious diseases are becoming more common in modern times?
A. Global population decrease which brings humans farther away from wild animals and their environments.
B. Global population increase which brings humans closer to wild animals and their environments.
C. Global population decrease which brings humans closer to wild animals and their environments.
D. Global population increase which brings humans farther from wild animals and their environments.
