Which of the following would most likely be key to gathering evidence that rna world hypothesis is valid

Simulation of early Earth conditions and long-term study of the resulting molecules

Explanation:

RNA World Hypothesis is the hypothesis or assumptions that was made concerning RNA and DNA Carl Woese, Francis Crick and Leslie Orgel during the 1960s.

RNA World Hypothesis states that RNA has always existed before DNA and for life forms the existed in the early days, it was RNA that was used as a store for genetic material.

From this hypothesis, we find out that due to the fact the RNA was very reactive and unstable, DNA evolved thereby allowing it to serves as a store for genetic material in this present day living organisms.

Simulation of early Earth conditions and long-term study of the resulting molecules is very essential and vital to to gathering evidence that RNA world hypothesis is valid.

answer; ///(b) it is composed of four protein chains and four heme groups;

step 1 ammonium can be absorbed by plants, but some is converted into nitrates which are better for plants to absorb. this is called nitrification. 2. step 2 the deer eats the plants and uses the nitrogen-containing proteins for cell growth. 3. step 3 bacteria in the soil conduct nitrogen fixation to convert nitrogen gas from the atmosphere into ammonium. 4. step 4 some of the nitrates are absorbed back into plants, but denitrification breaks down the nitrates into nitrogen gas released back into the atmosphere. 5. step 5 nitrogen is found in the urine, which gets broken down into ammonium through the process of ammonification. 6. step 6 plants absorb the ammonium and begin assimilation, the process to add the nitrogen to protein.
