The movement of heat from Earth's inner parts to the surface is approximately at 47 terawatts and comes from two major sources. These are the primordial heat left over from the Earth’s formation and the radiogenic heat caused by the radioactive decay of isotopes found in the mantle and crust. Earth's inner heat powers most ecological processes and handles plate tectonics. Despite its geological implication, this high temperature is coming from Earth’s inner part that is 0.03% of Earth’s total budget energy at the exterior that dominated by 173,000 terawatts of incoming solar radiation. the amount of solar radiation reaching a given area has eventually reached the surface after reflection into several tens of centimeters on the daily sequence and only various tens of meters on the yearly cycle. This provides solar radiation unrelated to inner processes.
The tundra biome has the least diversity of plant species. Due to the harsh cold environment, it's common to not see many plants.

Answer:
Vitamin D3 is synthesized in keratinocytes of the two epidarmal layers namely <u>stratum basale </u>(bottom layer) and <u>stratum spinosum</u>.
Explanation:
In the two epidermal layers of the skin namely <u>stratum basale</u> and <u>stratum spinosum</u>, 7-dehydrocholesterol (pro-vitamin D3) is converted to vitamin D3. This process takes place in the presence of ultravoilet radiations. Briefly, upon exposure, the pro-vitamin D3 is photolyzed to pre-vitamin D3. The pre-vitamin D3 then isomerized to form vitamin D3.
<span>Cellular respiration is the process of breaking down food such as
glucose into carbon dioxide and oxygen. During the process, cellular respiration
also releases energy in the form of ATP (adenosine triphosphate) for use by all
energy consuming activities of the cell. It is found in the simultaneous process
of Gycolysis and Kreb’s cycle. Glycolysis is the breakdown of glucose to two
pyruvic acids. These two pyruvic acids will be used for the production of
carbon dioxide and water in Kreb’s cycle. The answer is letter A.</span>
