How many children under the age of five succumb to the adverse effects of air pollution (particulates, mold, and bacteria), globally?

a) 6 000

b) 60 000

c) 600 000

c) 600 000. Furthermore, according to the UNICEF statistics, of all pneumonia-related mortalities of children under the age of five, half can be traced to air pollution.

Treating mold on walls using bleach will:

a) Kill the mold

b) Stop the mold from spreading

c) Contaminate the space with dangerous evaporations

c). Applying bleach to a mouldy wall will only contaminate the space with dangerous evaporations. Bleach only destroys the superficial part of the organism, while the rest of the mold and its spores can survive and continue to spread.

What is the difference between yeasts and molds?

a) Yeasts are larger than molds

b) Yeasts reproduce by water, while molds spread through air

c) Number of cells

c) Number of cells. Molds are multicellular, filamentous organisms, while yeasts are aggregations of single-cell organisms which aggregate and act as an individual. Interestingly, some fungi can revert from a yeast form to a filamentous form, depending on certain ecological conditions.

What is the main reason of mold infestation throughout most households in the world?

a) Unhygienic living conditions

b) Type of building material

c) Excess moisture

c). Moisture is the crucial ingredient for mold to thrive. Generally, the most common reasons for indoor mold spread are plumbing and roof leaks, wet basements, bad yard drainage, and high humidity.

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.

Certain molds can use one of the following to stimulate their growth:

a) Certain sound frequencies

b) Radiation

c) Fear hormones

b). Radiation. Some melanin-producing molds, such as Cladosporium sphaerospermum, can use radiation to increase the rate of their metabolism, eat more and grow several times faster. Interestingly, experiments conducted on the International Space Station showed the potential of these molds to be used for radiation shielding during long space flights.

Long-term exposure to mold spores can cause:

a) Allergies

b) Pneumonia

c) Eye infection

d) Necrotic tissue

e) All of the above

e) All of the above. Prolonged exposure to molds can induce many different health problems, with intensity depending from mild irritations in healthy people to life-threatening infections in immunocompromised patients.
