Answer:
All matter consists of atoms that contain a nucleus and orbiting electrons . The nucleus consists of two kinds of atomic particles called protons and neutrons, collectively known as nucleons.
In the physical sciences, subatomic particles are smaller than atoms.[1] They can be composite particles, such as the neutron and proton; or elementary particles, which according to the standard model are not made of other particles.[2] Particle physics and nuclear physics study these particles and how they interact.[3] The concept of a subatomic particle was refined when experiments showed that light could behave like a stream of particles (called photons) as well as exhibiting wave-like properties. This led to the concept of wave–particle duality to reflect that quantum-scale particles behave like both particles and waves (they are sometimes described as wavicles to reflect this[citation needed]). Another concept, the uncertainty principle, states that some of their properties taken together, such as their simultaneous position and momentum, cannot be measured exactly.[4] The wave–particle duality has been shown to apply not only to photons but to more massive particles as well.[5]
Cells are the basic building blocks of all living things. The human body is composed of trillions of cells. They provide structure for the body, take in nutrients from food, convert those nutrients into energy, and carry out specialized functions. Cells also contain the body’s hereditary material and can make copies of themselves.
