Answer
Its organism.
Explanation:
An arctic fox isn't an area it is a living thing so organism.
Available oxygen
Available oxygen is the amount of oxygen present at a specific time that can be used in aerobic cellular respiration.
Aerobic cellular respiration is a metabolic process that occurs within the cells of organisms. In this process, oxygen is used in the mitochondria to chemically convert organic molecules such as glucose into adenosine triphosphate (ATP), with the release of water and carbon dioxide as waste products. Aerobic cellular respiration results in a larger amount of energy (ATP) which is used by the cell to perform its activities.
A, because, the entire point of his theory was to prove that changes don't happen spotaneously!
A clastic rock composed of sand-sized grains derived from the physical weathering of granite and containing a sizable proportion of feldspar is termed as arkose. It is a sedimentary rock that has a composition of at least 25% feldspar. It is a type of sandstone that has a coarse texture and is commonly in gray or pink in color. The most important minerals in arkose are feldspar and quartz. And, it is quartz that is dominant in composition. This rock is formed from weathering of metamorphic or igneous rock that are rich in feldspar. They are to be quickly deposited into cold environments so as to avoid chemical weathering.
