Practise MYP Biology questions on 7.4 Pathogens and Parasites and review the explanations to check your understanding.
Use these questions for topic practice and to find ideas you want to revisit in your notes or lessons.
How does the manipulation of host behavior by certain parasites specifically aid in the parasite's reproductive success?
In the context of ecosystem interdependence, a decrease in the population density of a host species is most likely to result in:
Fungi typically infect host organisms by spreading __________ that land on tissue and digest cells externally.
Which group of parasites is characterized by being multicellular and often using specialized structures like hooks or suckers for attachment?
Pathogens harm their hosts by __________ host resources, which reduces the energy available for the host's growth and reproduction.
It prevents the host from being detected by other predators
It forces the host to move to locations where it is more likely to be eaten by the next host
It causes the host to produce more nutrients for the parasite to absorb
It makes the host stay in its nest to infect its own offspring
A sudden increase in the virulence of the pathogen
A decrease in the transmission rate of the pathogen
The pathogen immediately evolving a non-parasitic life cycle
The host species becoming completely immune to the pathogen
