Answer:
An atom consists of protons, electrons, and neutrons.
Explanation:
The atom of an element is its smallest indivisible particle that retains its chemical properties. Atom is the fundamental and basic unit of matter.
The structure of an atom is made up of a positively charged PROTON, a neutrally charged NEUTRON (both contained in the nucleus) and a negatively charged ELECTRON that surrounds the nucleus. These three particles are called sub-atomic particles. The arrangement and number of these sub-atomic particles determine the properties of the atom.
The answer is A. Commensalism

If the statue is like Lady Liberty, and overgoes a change in color and state. For example, she was originally copper, but later changed into patina due to weather such as acid rain, it is mechanical weathering. Please let me know if this helped.
This is because cellulose is composed of beta glucose units, unlike starch that is formed using alpha-glucose units. The beta acetal linkage between units allows for linear chains hence branches are unlikely. The alpha acetal linkages allow for spiral chains. The beta glucose is good for structural polysaccharides because it allow for best interaction between polymer chains and increases the integrity and strength of the cells wall.
