I'm a chemist, and frankly even I've never heard anyone so biased as to make this claim.
Physics, maybe (Ernest Rutherford once famously said "All science is either physics or stamp collecting"); math, sure, I've heard that too. Chemistry? Not so much.
However, chemistry might be considered as the basis for all biological science.
Combined Sciences means that all the man sciences are combined together in the subject. That means Physics,Chemistry,Biology together.
Chemistry and Physics are the central sciences. There is little separation between the two at a theoretical level. All the other sciences depend upon these.
Mathematics is used in all the sciences.
Some sciences that are similar to physics include chemistry, astronomy, and earth sciences. These sciences also use systematic observation, experimentation, and mathematical models to understand the natural world. They may also overlap with physics in areas such as thermodynamics, electromagnetism, and mechanics.
Preparation of foods and fuels, production of drugs and cosmetics, treatment of wastes of all types, fabrication of rubber, plastics, cement, other building materials, dying agents, cleaning agents, preparation of materials for electronic products, fertilizers, pesticides, etc., etc. Chemistry is around us, all is chemistry and chemical products; chemistry may be considered the queen of the sciences.
Chemistry has contributed to other sciences by providing fundamental understanding of chemical reactions, materials, and structures. It has helped advance fields like biology, medicine, and environmental science through techniques such as drug development, molecular imaging, and pollution control. Chemistry also plays a key role in interdisciplinary fields like biochemistry, pharmacology, and materials science.
Without chemistry, the world wouldn't have all of the medicines that are in use today. Chemistry and other sciences provide information businesses can use to produce products.
Classifying halp to understand, learn and study chemistry; and this is valuable for all sciences.
No, it gets information from all other sciences you have to know about BIOLOGY, BIOCHEMISTRY, CHEMISTRY..
When it comes to the physical sciences like chemistry and physics, math is the "language" of chemistry and physics. You won't need any advanced math in high school or general chemistry, but go into the upper division courses in college and you utilize a lot of calculus. You simply can't do chemistry without math. All physical sciences and math require very similar ways of thinking as well.
Mathematical science has a real world application in almost all other sciences.
Biotechnology is a part of Biology, although Chemistry may be involved on it. On the other side Biotechnology could be involved with Chemistry. Generally, all sciences are involved one to another on many aspects.
