Question 2

What is the danger associated with agricultural monocultures?

Accepted Answer

Monocultures are highly susceptible to crop diseases because if an appropriate pathogen invades the crop, the pathogen will rapidly spread throughout the monoculture, causing complete crop failure. A human population that depends on this monoculture is then at risk for famine. Such total destruction of a plant community is rare in natural ecosystems because such ecosystems generally consist of many plant species. It is unlikely that any plant pathogen can attack more than a few plant types. The danger of monocultures in agriculture can be mitigated by growing a variety of crops in the same area, since it is unlikely that any one plant pathogen can damage all crops.

Question 3

Four flasks are prepared with a broth that supports microbial growth. Broth A is boiled and then sealed to prevent the entry of air. Broth B is boiled and left open to the air. Broth C is boiled and left open, but the flask is fitted with an S-shaped neck. Broth D is boiled, left open to the air, and fitted with an S-shaped neck, but after two days the neck is removed. If the broths are examined after four days, which ones will contain living microorganisms?

Accepted Answer

A)  All broths will contain microorganisms. 
B)  None of the broths will contain microorganisms. 
C)  broths B & D 
D)  broths A & C 
E)  broths B, C & D 
A)  All broths will contain microorganisms.
