Under what conditions is sterilization by filtration preferred over sterilization by heat?
When a liquid is heat labile or can be destroyed by heat then this method is used.
What are the natural substance found in rocks?
Crystals and minerals, but not fossils, as the intense pressure would have destroyed them (except in some rare contact metamorphic rocks).
What is the principle that illustrates chemical elements from minerals and rocks are not lost or destroyed but changed to new form?
Metamorphic rock
What satellites or missions have explored Venus?
Yes satellites have visited space but they were destroyed by the heat pressure
How does a foliated metamorphic rock from?
Schist is a typical foliated metamorphic rock. Initially, one merely has a laminated sedimentary rock. When this is subjected to heat and pressure, then some of the old minerals are destroyed and new ones formed from the available assemblage. From the types of new minerals formed, one may deduce the heat and pressure of the metamorphism. The date of the metamorphism is estimated by dating the mineral last formed - the one with the lowest freezing point. [Commonly mica]. The rock may then be subjected to further stresses which will produce folds of some complexity. This may be followed by intrusions of granites or volcanics.
Does heating kill vitamins and minerals?
No, it does not. Some forms of cooking can remove vitamins and minerals from food but they are not destroyed. Matter can not be created or destroyed, it will always exist in some form.
What is heat labile depyrogenation?
Pyrogens that are destroyed by heat.
Can botulism endospores be destroyed by heat?
no
Do minerals stay the same during metamorphosis?
Earth movements form metamorphic rocks by pressing, squeezing, and folding. Sometimes minerals are destroyed and new minerals are created
What turns minerals into gemstones?
heat and pressure
What Effects of heat on vitamins and minerals?
When you heat vegetable they lose most of their "vitamin value".
Does heat destroyed viatmin K?
Yes, indeed it does.
How can you destroy a diamond?
adiamond can be destroyed by intense heat!
What vitamins and minerals can withstand heat?
Vitamin C is one vitamin that can withstand heat. However, minerals like vegetable oils can also withstand very high temperatures.
What does heat do to a rock?
At high temperatures, the minerals in a rock can change to other minerals. And, of course, rock can melt.
Is ozone destroyed in transforming UV radiation to heat?
Yes, it is destroyed. However it is replenished using the same source.
What are inorganic nutrients that are not broken down by the human body or destroyed by heat?
There are several nutrients that are required by the human body that are not broken down by the body or destroyed by heat, including:* ...* ...* calcium* iron* ...
