a. low humidity
it may be rust.
Yes, but mold may still continue growing with less moisture than what it takes to germinate mold spores(about 60% RH). Mold also tends to release more spores as it dries out which aids in "spreading the colony" so to speak. This is one of the reasons a removal or cleaning of mold is recommended along with preventing the moisture which caused it to grow in the first place. Moisture prevention is #1 but cleaning is also beneficial, especially to those few who may have allergic reactions to the mold.
Seeds do not always germinate. Some fail because they were never fertilized, but others fail because the growing conditions aren't right. The climate may be too hot or too cold, or conditions may be too dry. They may also fail to germinate if they have been infected with mold or disease.
2. The bacteria may release a substance that prevents mold growth.
Mold is not safe to eat, whether it is growing on cheesecake or anywhere else. Some species of mold are quite toxic, and may result in pancreatic cancer. Don't eat it.
No. There are certain conditions that may prevent this...
In the US the word "mold" generally refers to any of a group of fungi which can infest the growing crop. Depending on the severity of infestation, the crop may be only slightly damaged, or it could be completely destroyed.One example is white mold in beans, caused by the fungus Sclerotinia sclerotiorum. It usually infects the lower part of the plant first, but if conditions are favorable, it can kill the entire plant.
A flight attendant can have health conditions but some health conditions may prevent a flight attendant from getting the job.
Crowded conditions, inadequate ventilation, infrequent housekeeping, regular moisture, and unsealed cracks are reasons why closets have mold. Clothes may not be adequately dried, and damp towels or soiled socks may be left on the floor. Order, sanitation, and security are three ways to discourage mold.
The best way you can tell if you have mold growing inside your walls is to look for moisture. If you spot water damage on a wall, it is a good indication that there may be mold growing inside. Mold also has a distinctive, musty smell, so you should be aware of that.
This depends very much on the conditions the mold was grown under. For instance, if we are comparing how mold grows in light versus how mold grows in the dark, our null hypothesis may be 'Mold grows more rapidly in light than in the dark'. An essential factor to consider when setting a hypothesis is to ensure that it is testable (i.e. we are able to test the validity of the hypothesis and choose to accept/refute it). Hence, a statement such as 'Mold grows better in light than in the dark' is not testable (and would thus not qualify as a hypothesis), since there is no scientific definition of what is being implied by the term 'better'.
