Which of material is resistant to boiling aqua regia?
Gold and platinum are both highly resistant to the corrosive effects of boiling aqua regia, a mixture of nitric acid and hydrochloric acid. These metals do not react with aqua regia and can withstand prolonged exposure to it without being dissolved.
Do some bacteria surround themselves with a tough resistant wall and become spores that can survive dryness and low temperatures but die in boiling water?
Yes, some bacteria can form spores when conditions are unfavorable for growth, such as dryness or low temperatures. These spores have a tough resistant wall that protects them from harsh conditions but they can be killed by boiling water due to the high temperature denaturing their essential proteins and enzymes.

How Glass carafe boiling water?
Boiling water in a glass carafe is not recommended because the sudden temperature change can cause the glass to crack or shatter. It's safer to use a kettle or heat-resistant container made specifically for boiling water.
Are leptospira species resistant to heat?
Leptospira species are not resistant to heat and can be killed by high temperatures. Proper heat treatment, such as boiling water or steam sterilization, can effectively control and kill Leptospira bacteria.
What does resistant or susceptible mean?
These terms refer to antibiotic sensitivities; antibiotic resistant organisms versus antibiotic susceptible organisms.

What is an antibiotype?
An antibiotype is a set of organisms which are resistant to a particular antibiotic.

Why do insecticide resistant organisms develop?
Evolution. Each generation has some differences from the preceding generations. The survivors from one generation pass their genes on to subsequent generations. A trait that increases survival rate (resistance to an insectide) is passed on more frequently than a trait which is detrimental to procreation.
Why is the overuse of antibiotics a problem?
It exposes too many organisms to antibiotics, and exposing them too frequently. This results in the opportunity for the organisms to become resistant to the antibiotics. Antibiotic resistant bacteria are becoming a more and more serious public health threat.

Leptospira species are not resistant to heat and can be killed by high temperatures. Proper heat treatment, such as boiling water or steam sterilization, can effectively control and kill Leptospira bacteria.
Are Teflon material is resistant to boiling aqua regia?
Teflon is not resistant to boiling aqua regia, which is a powerful corrosive mixture of nitric acid and hydrochloric acid. Aqua regia can degrade and dissolve Teflon over time. It is advised to use materials like glass or certain metals for handling aqua regia.
What organisms are not killed during pasteurization?
Some heat-resistant organisms like bacterial spores, thermoduric bacteria, and certain enzymes may survive pasteurization processes at typical temperatures and times. These organisms can affect the shelf life and safety of the product if not properly controlled through other means.
