Question

A hurricane tore holes in the roof of your house, allowing a good deal of moisture inside. Very quickly, mold began to grow because of it. What would be the most effective and ecologically friendly way of killing the mold and why?

a. Since mold is one of the immobile protists, releasing heterotrophic protists to act as predators would kill it.
b. Since mold is an autotrophic protist, depriving it of light would keep it from photosynthesizing, and it would die.
c. Since protists need moist environments in order to grow well, drying out the area would kill the mold.
d. Since protists need to move their flagella to gather food, spraying red tide toxins on the mold would paralyze and kill it.

Answer 1

c. Since protists need moist environments in order to grow well, drying out the area would kill the mold. 

Answer 2

The right option is; c. Since protists need moist environments in order to grow well, drying out the area would kill the mold.

Molds are woolly or fury growth of tiny fungi that appears when organic materials lies for a long time exposed to (usually moist and warm) air. Molds can survive and grow almost anywhere that moisture and oxygen are available. The most effective and ecologically friendly way of killing molds is by drying out the affected area to remove excess moisture which can allow their spores to germinate. After drying out the area, the fungus should be removed physically (by discarding contaminated porous materials and cleaning non porous surfaces) in order to avoid mold growth in the future.
