Out of a hundred cases of chronic sinusitis (the most common chronic sinus infections), how many cases are mold-related?

a) 15

b) 56

c) 96

c) 96. A clinical survey discovered mold in mucus of 96% of patients suffering from chronic sinus infections, a disease which annually impacts more than 20 million adults U.S.

What is the molds function in an ecosystem?

a) To infect weaker organisms, thus strengthening a population

b) To recycle organic matter

c) To make symbiosis with plants and help them grow

b) To recycle organic matter through decomposition and mineralization. In fact, everything lignin-containing can only be dissolved by saprophytic fungi, without which life on this planet wouldn’t be possible due to sheer amounts of debris formed by undecomposed plant material.

a) Because they look like pencils

b) Because of their smell

c) Because they look like paintbrushes

c) Because they look like paintbrushes – The entire genus Penicillium got its name because their spore-bearing structures look like paintbrushes, which are called “penicilli” in Latin.

What are the chances of developing respiratory or asthma-related health problems due to the building dampness and mold exposure?

a) 30-50%

b) 1-5%

c) 100%

a) 30-50%. Studies show that consistent associations of dampness with adverse health effects, strongly suggesting a causation by dampness-related exposures.

Molds are genetically closest to:

a) Plants

b) Humans

What is the difference between molds and slime molds?

a) Slime molds are aquatic molds

b) Molds are fungi, while slime molds are not

c) There is no difference

b). Molds are multicellular, filamentous fungi, while slime molds belong to a more primitive group of organisms called the Protista, which form unicellular or colonial forms such as amoebas and primitive algae.

b) Ingestion

c) Inhalation

d) All of the above

d) All of the above. Furthermore, prolonged exposure to mold can manifest in symptoms ranging from rashes, allergies and flu-like symptoms to neurological damage and even death.

Chemical structure of cellular walls of mold fungi is similar to:

a) Plants

b) Lobsters

c) Armadillos

b) Lobsters, because the shell of arthropods (crustations, insects, spiders, and such animals) and the cell walls of fungi (molds) are made of chitin, a structural polysaccharide (sugar) molecule.
