Their chemical balances are maintained by acid-base reactions.
The study of the chemistry of living organisms is called organic chemistry.
All around us, living things or inorganic things are chemical compounds.
carbon
Yes, it is only true for living things that are small.
Various branches of science deal with non-living things, but you may be thinking of Chemistry - which is usually split into Organic Chemistry and Inorganic Chemistry. Inorganic would deal with the chemistry of non-living things.
Carbon.
organic chemistry
Yes, living things are composed of physical matter and energy, so their biological processes are governed by the principles of chemistry and physics. The interactions of molecules, energy transfer, and motion within living organisms all follow the same fundamental laws that apply to non-living systems.
True.
chemicals are the fundamental parts of all living things.
Chemistry is the basis of all things living and non-living. Any biological process that occurs from the nitrogen cycle, photosynthesis, how your body breaks down food, etc. are all chemistry if you go deep enough.
Biochemistry simply describes the chemical processes that occur in living things. An example of a chemical process that goes on your body is the breakdown of proteins and other compounds that you it. The food that you eat undergoes a chemical reaction with the natural acids produced in your stomach. Biochemistry is literally "bio" (anything living, biology) plus "chemistry", and therefore the chemistry of living things.
