Answer:
The answer is FALSE.
Explanation:
The pink color that the nail bed presents is due to the significant number of blood vessels, specifically capillaries, coursing under the skin. This usually indicates a healthy nail bed. Any discoloration away from the pink color would usually indicate an underlying disease.
For example, if it turns <u>yellowish</u>, it may be an indication of <em>jaundice</em> or <em>liver disease</em>. If it's <u>bluish to whitish</u> in color, <em>hypothermia or anoxia</em> may be present. A distinct condition called <u>Onychomycosis</u>, a <em>fungal infection</em> of the nail, may produce whitish to yellowish discoloration with accompanying thickening of the nail bed.
The surface of the early Earth is often described as hellish by scientists. The high temperature is primarily attributed to the high levels of carbon dioxide in the atmosphere and the molten rock on the surface of the planet. However, these two aren't the only factors in play.
Another factor that contributed to the extremely high temperature of the early earth is radioactivity. Radioactive decay of the isotopes found underground plus the left over heat from the formation of our planet produced high levels of radiogenic heat.
There's also the kinetic energy from falling asteroids and meteorites. Massive amounts of energy in the form of heat and sound is produced when asteroids and meteorites hit the Earth. Also, the pressure waves that travel radially outwards the center of the impact is similar to the impact of an atom bomb. As such, dust particles envelop the atmosphere, trapping the heat from the impact.
The last factor is the gravitational contraction, it contributed to the hellish temperature of primordial Earth because the energy generated from such event is enough to trigger hydrogen fusion.
A formation of a mixed....
Sunlight is the main change! sun light cannot penetrate into the deep layers of the ocean and availability of oxygen is also low there. this causes the considerable amount of organisms to live in the upper layers of the ocean and we can only observe decomposing organisms in the deeper layers!
