The Size Difference Between Most Multicellular Hosts and Their Pathogens

question 43

Multiple Choice

The size difference between most multicellular hosts and their pathogens results in which of the following evolutionary advantages for the pathogen?

• A) Pathogens have larger population sizes and shorter generation times than hosts, allowing for increased rates of adaptation.
• B) Pathogens have lower mutation rates than hosts, resulting in more stable populations.
• C) Hosts evolve more rapidly due to mutations induced by the pathogen.
• D) Host population sizes increase in the presence of a pathogen, providing more potential hosts for infection.

Definitions:

Diaphragm

A dome-shaped, muscular partition separating the thorax from the abdomen in mammals, playing a major role in breathing as its contraction increases the volume of the thorax and so inflates the lungs.

Intercostal Muscles

Muscles located between the ribs that play a role in the mechanics of breathing.

Atmospheric Pressure

The pressure exerted by the weight of the atmosphere above a specific point, affecting weather and climate conditions.

Respiratory Rhythm

The regular or irregular pattern of breathing controlled by neural mechanisms in the brain.
