There are a number of metals which are called trace elements, that the body needs in very small amounts; these include copper and zinc.
NO!!! It does not occur naturally. However, its mineral ores are very common. e.g. Haematite, Magnetite.
Alcoholic Fermentation does not occur in human bodies but rather in plant cells when they do not receive adequate amounts of the necessary amounts of nutrients and minerals. Lactic fermentation however occurs in human cells located in the cytoplasm after glycolysis.
In the case of animals, these exchanges occur in the capillaries.
Blood glucagon increases
There are really no steps in natural selection - just conditions required for it to occur.

No, Technetium does no occur naturally on earth except in trace amounts in molybdenum deposits.
No, phosphorus-32 is a radioactive isotope of phosphorus and is not found naturally in significant amounts. It is typically produced in nuclear reactors or particle accelerators.
Yes, thallium occurs naturally in the Earth's crust, typically in association with sulfide ores of heavy metals. It is a relatively rare element and is often found in small amounts as a trace element.
Yes. but it is a very rare naturally occurring element.
Hematite does not typically contain nickel. It is primarily composed of iron oxide and does not naturally occur with significant amounts of nickel.
So2 causes acid rain. So we can find sulphuric in nature.
Tritium does occur naturally in very small quantities in the Earth's atmosphere due to interactions with cosmic rays. It is also produced in small amounts during nuclear reactions in stars. However, most tritium found on Earth is produced artificially for various uses.

Xenon occurs naturally in trace amounts in Earth's atmosphere, where it is produced by radioactive decay. It can also be found in certain mineral springs and in trace amounts in some rocks and minerals. Additionally, xenon is produced as a byproduct of the process of nuclear fission.
