Question 1

Are all fungi detrimental (bad) for other organisms?

Accepted Answer

A)  Yes-think of molds that destroy plant crops, or fungal infections that cause athlete's foot. All fungi are bad for organisms they colonize. 
B)  Yes-fungi feed directly on organic material. They usually kill the other organism and feed on it after it has died. As such, they are always bad for other organisms. 
C)  No-it depends on the fungus and the relationship it has with the other organism. Some fungi can form a symbiotic relationship with plant roots that increases their nutrient and water absorption. This is good. 
D)  No-fungi are ALWAYS good when they interact with other organisms. There is never a negative aspect to such interactions. Both sides always benefit from the relationship. 
E)  Yes-fungi are generally parasitic. Parasitic relationships always result in damage to the host organism while the parasite benefits from the association. As such, fungi are always bad for other organisms.

Question 3

How would increased travel lead to increased spread of multicellular eukaryotic parasites?

Accepted Answer

A)  Many eukaryotic parasites are transmitted directly from person to person via airborne transmission, so getting an infected individual onto a plane of susceptible individuals would increase spread. 
B)  Many eukaryotic parasites depend on vectors (often small blood-sucking insects) for transmission, so moving an infected individual into an area with new vectors and new susceptible humans would increase spread. 
C)  It really would NOT; most individuals are screened for parasitic infections prior to traveling out of highly infected areas. We also have quarantine abilities at customs stations for individuals entering the United States. 
D)  Eukaryotic parasites are too small to travel great distances effectively; by hitching a ride on luggage, clothing, fruit/vegetables, and other food products, they can enter new geographic areas. 
E)  Traveling generally weakens a person's immune system, making them vulnerable to parasitic eukaryotes in any new place that they visit.
