There are probably no elements, beyond the extremely unstable nuclides, that you could not find in the human body at some level.
Is water. water is one of the chemical compound that takes part in human body.
Because almost 78% of human body is made of water.
naturally occurring selective pressures favor new traits, humans create new environmental conditions
It is the Duodenum!Actually, most chemical digestion, in humans, takes place in the small intestine.Chemical digestion takes place in the small intestine, the stomach and the mouth.
chemical receptors
Plants and some algae get their energy from the Sun. Most other living beings (including us humans) get their energy from plants. Energy is stored as chemical energy, which we use. Plants use chemical energy, too, as energy storage.Plants and some algae get their energy from the Sun. Most other living beings (including us humans) get their energy from plants.

Oxygen is a gas that does not naturally replenish itself in the atmosphere and requires the work of photosynthesizing plants to replenish it. Humans breath oxygen that plants produce and the plants breathe the carbon dioxide that humans produce.
Quinine
An ascorbic acid is a naturally occurring organic compound and it has antioxidant properties. It is essentially Vitamin C that humans need in their bodies.
Substantial heat, whether produced by humans or naturally occurring, can melt rock.
Yes - diamonds occur naturally in nature. Humans refine their shape to produce gemstones.
Red is a naturally occurring colour, it's been around longer than there's been humans.
No. A dump doesn't appear without human involvement. Dumps are created by humans, not nature.
The South Pole is a physical feature. It naturally-occurring, which means that humans do not play a part in the 'creation' of it.
SDLC refers to a stage all systems naturally undergo, a methodology refers to an approach invented by humans to manage the events naturally occurring in the SDLC
Ice meets the criteria that defines a mineral; solid, crystalline structure, definite chemical formula, naturally occurring and inorganic. It is recognized as a mineral by the International Mineralogy Association.
The principal elements are C, O, H, N, P, Ca, etc.

Nothing. Ligers are not a naturally-occurring species of animal; they exist only because humans have bred them into existence. There is no need to save them.
