Why do the crystals of Bt toxin produced by some bacteria do not kill the bacteria themselves?
toxin is inactive: In bacteria, the toxin is present in an inactive form, called prototoxin, which gets converted into active form when it enters the body of an insect
What Bacteria return nutrients to the environment by breaking down?
Decomposers, such as certain bacteria, break down organic matter into simpler compounds. This process returns essential nutrients like nitrogen and phosphorus back to the environment, making them available for other organisms to use.
What is the relation between fermentation of milk and PH?
During milk fermentation, bacteria convert lactose into lactic acid, which lowers the pH of the milk. As the pH decreases, the acidity of the milk increases, creating an environment that promotes the growth of beneficial bacteria while inhibiting the growth of harmful bacteria. A lower pH also contributes to the characteristic tangy flavor and thickened texture of fermented milk products like yogurt.
A tree leaf becomes part of humus when?
A tree leaf becomes humus after it decomposes completely as a result of being consumed ad excreted by insects, worms, bacteria.
A bacterial disease becomes difficult to cure when the bacteria?
develop resistance to antibiotics, making them less effective in treating the infection. This resistance can occur through genetic mutations or the acquisition of resistance genes from other bacteria through horizontal gene transfer. As a result, common antibiotics may no longer be able to kill the bacteria, leading to treatment failures.
Can bread decay without the covering such as cling wrap or a container?
No because bacteria thrives in moist places. When the bread is deprived of water and becomes very dry, it is not a suitable enough environment for bacteria to grow thus no mould is produced.
What forms when a hair follicle becomes infected with bacteria?
When a hair follicle becomes infected with bacteria it becomes irritated. When a hair follicle becomes infected it might fall out.
What type of chemical reaction occurs when butter is kept in open air so that it becomes smelly?
butric acid is formed or produced due to a kind of bacteria

Why mild steel is unsuitable for the very low temperature involved in the containment of liquefied gases?
At the very low temperatures required it becomes brittle.
What makes bacteria mutate?
Bacteria mutates when it is multiplying and there is a genetic error. Also Mutation occurs when bacteria becomes resistant to an antibacterial medicine.
What Bacteria return nutrients to the environment by breaking down?
Decomposers, such as certain bacteria, break down organic matter into simpler compounds. This process returns essential nutrients like nitrogen and phosphorus back to the environment, making them available for other organisms to use.
How do bacteria survive harsh conditions?
They form an endospore. An endospore is a thick cell wall that helps protect them. Endospores enable bacteria to lie dormant for extended periods of time when the environment is unfavorable (such as extreme temperatures, radiation, extreme pH levels, extreme pressures and harmful chemical agents). Then, when the environment becomes more favorable, the endospore can reactivate itself to the vegetative state.
