Miller-Urey supported the Primordial Soup Hypothesis because it concluded that organic molecules could be

produced in the presence of certain inorganic best explain the relationship between Miller-Urey and Primordial soup.

The Miller Urey experiment refer to a form of chemical experiment that simulated the conditions present on the early Earth and tested the chemical origin of life using those conditions . The experiment performed at the time supported Alexander Oparin's and J. B. S. Haldane's hypothesis that putative conditions on the primitive Earth is important for chemical reactions to produce more complex organic compounds from simpler inorganic precursors.

The first was the “primordial soup” which was a conclusion that when Earth was young, the oceans were filled with simple chemicals important for life and this assemble into living cells.

Therefore, Miller-Urey supported the Primordial Soup Hypothesis because it concluded that organic molecules could be

Answer:

Ribosomes create the thermoreceptors of the body. Another example of a homeostatic condition maintained by proteins is blood-glucose levels. When our blood-sugar levels get too high, specialized cells in the body release a protein hormone called insulin.

Have A Great Day

Answer: Ribosomes play a key role in homeostasis. Without ribosomes, a cell would not make proteins. A cell with no ribosome would simply not function. With no protein reproduction to maintain the cell wall there would be no barrier to keep invasive bodies from damaging the inner workings of the cell, there would be no way to produce the needed proteins for rebuilding and maintaining the cell.

The answer would-be producers. The fact that there are primary consumers today, you would know that producers make up the bigger population. If it were smaller, the primary consumers would have eaten them all up and eventually would die out because they would have no more food source. This would be bad for all higher-level consumers.

We record the elements present in each unknown astronomical object according to metallicity.

To understand these answers, we need to know what metallicity.

In astronomy and physical cosmology, metallicity (also called Z) of an object is the proportion of its matter made up of chemical elements other than hydrogen and helium. Because stars, which make up most of the visible matter in the universe, are composed primarily of hydrogen and helium, astronomers conveniently use the generic term "metal" to describe all other elements collectively.

With this information, we can conclude that we have recorded the elements present in each unknown astronomical object according to metallicity.
