Answer: mathematics
Explanation:
Mathematics is the study of quantity, space, structure of a concerned entity or population size. A scientific experiment may be based on the analysis of variables must be having large sample size. Therefore, quantitative estimation of the results is required. Hence, a scientist requires mathematics to interpret the results of a scientific experiment.
In organic molecules, the atoms are linked by covalent bonds. Organic molecules are generally large and may be complex, involving many such bonds. Inorganic compounds have considerably simpler structure in terms of number, but not necessarily type, of bonds. In organic molecules, to a first approximation, we may say that one bond does not affect another. Thus an atom such as a chlorine atom, -Cl, or a group of atoms such as the alcohol group, -OH, on one end of a molecule will behave chemically in the same way almost without regard to the molecule to which it is covalently attached. The idea of different independent or semi-independent atoms or groups of atoms on the same molecule is central to our modern understanding of organic chemistry. It is called the concept of functional groups. The nomenclature of organic compounds, like most of the rest of our understanding of reactions of organic compounds, is based upon the concept of functional groups.
When two sea caves on opposite sides of a headland are eroded and unite a sea arch forms.
Sea arch is a natural opening and a type of erosional landform that forms due to different rates of erosion, usually as a result of different resistance of bedrock. Sea arch is made up of a soft rock that eroded as waves hit land which creates caves in the rock. Two caves may become jointed over some time to form a tunnel and eventually, a sea arch.
Answer:
Primary succession begins in barren areas, such as on bare rock exposed by a retreating glacier.
