Why are Aerobic and anaerobic bacterial spore former more heat resistant than tubercle bacillus?
Aerobic and anaerobic bacterial spore formers have specialized structures called endospores that protect their genetic material from harsh conditions like heat. These endospores are highly resistant to heat, making the bacteria more heat-resistant overall. In contrast, the tubercle bacillus (Mycobacterium tuberculosis) lacks such protective structures, making it less heat-resistant than spore-forming bacteria.
Why do microorginisms differ in their response to disinfectants?
The microorganisms DNA is different than others. These different DNA strands can have resistances to some things that others don't. however if an organism is only partially exposed to a disinfectant it may grow resistant and more powerful. This creates more powerful strains of viruses and bacteria which can be deadly.
Why are some microorganisms more infectious than others?
Some microorganisms are more infectious than others due to factors such as their ability to evade the host immune response, their mode of transmission, and their efficiency in invading and replicating within host cells. Factors like virulence factors or toxins also play a role in determining the infectiousness of a microorganism.
Explained why fungi and Bacillus sometimes grow better after heat treatment?
Fungi and Bacillus are capable of producing endospores. The endospores provide a great "niche" for microbes to chill until conditions are optimal. However, sometimes heat activates these endospores. Meaning, the Bacillus is able to divide and replicate after heat because the heat activated the endospore.
How does biofilm work?
A biofilm is a group of microorganisms in which cells stick to each other. The formation of a biofilm begins with the attachment of free-floating microorganisms to a surface. If the colonists are not immediately separated from the surface, they can anchor themselves more permanently using cell adhesion.
Can dry heat kill spores?
Yes, dry heat can kill spores at high temperatures over a period of time. Spores are more resistant to heat compared to other forms of microorganisms, so longer exposure to high heat is required for effective sterilization.
Are some microorgamism more resistant to heat that otherswhy?
Yes, some microorganisms such as thermophiles are more resistant to heat because they have evolved to survive in high-temperature environments. These organisms have specialized proteins and cellular structures that allow them to withstand high temperatures without denaturing or being killed.
Why is B Cerus more heat resistant than A Niger?
B. cereus is a spore former. Spores are known for their very high heat resistant qualities.
How many degrees to curl you hair?
it depends on the texture of your hair , different hair can handle different heat levels and some hair is more resistant than others

Which group of microorganisms have the property of highly resistant endospores under certain growth conditions?
Group C. I'm in microbiology right now. Group A are vegetative forms of most bacteria and enveloped viruses that are easily killed by disinfectants. Group B are more difficult to kill, like tuberculosis baccillus and unenveloped viruses. and Group C have highly resistant endospores.
How can ordinary glass be made heat-resistant?
Ordinary glass can be made heat-resistant by adding certain compounds such as boron or alumina during the manufacturing process. These compounds help to strengthen the molecular structure of the glass, making it more resistant to thermal shock. Additionally, the glass can be treated with a special coating or undergo a tempering process to enhance its heat resistance.
What is HR glass?
HR means heat resistant - if if find any more info ill post
Is the higher the R-value of insulation the less resistant to heat flow?
No, this statement is inaccurate. The higher the R-value of insulation, the more resistant it is to heat flow. R-value measures the effectiveness of insulation in resisting heat transfer, with higher values indicating better insulation properties.
Which is stronger - steel or wood beams when it comes to fire and heat resistance?
Steel is inherently more flame resistant.
