Answer:Living things are highly organized and structured, following a hierarchy that can be examined on a scale from small to large. The atom is the smallest and most fundamental unit of matter. It consists of a nucleus surrounded by electrons. Atoms form molecules which are chemical structures consisting of at least two atoms held together by one or more chemical bonds. Many molecules that are biologically important are macromolecules, large molecules that are typically formed by polymerization (a polymer is a large molecule that is made by combining smaller units called monomers, which are simpler than macromolecules). An example of a macromolecule is deoxyribonucleic acid (DNA), which contains the instructions for the structure and functioning of all living organisms.
Answer:
D .physical processes observed today (such as erosion and volcanic eruption) occurred much more rapidly in the past, quickly sculpting the Earth’s surface.
Explanation:
physical processes observed today (such as erosion and volcanic eruption) have been active in the past and are responsible for the geologic history we see preserved in the rock record.
Uniformitarianism, in geology, the doctrine suggesting that Earth's geologic processes acted in the same manner and with essentially the same intensity in the past as they do in the present and that such uniformity is sufficient to account for all geologic change.
The Principle of Uniformitarianism states that the laws of nature that are in effect today, have been in effect forever. The major folds and unconformities seen in rocks could not have been produced in such a short time if the principle of uniformitarianism is applied.
Answer:
peninsulas and islands
Explanation:
In contemporary definition, Southeast Asia consists of two geographic regions: Mainland Southeast Asia, also known as the Indochinese Peninsula and historically as Indochina, comprising Cambodia, Laos, Myanmar, Peninsular Malaysia, Thailand, and Vietnam.
