<span>Mendeleev was the first scientist to arrange the known elements into a table. Mendeleev decided to arrange the known elements by atomic weight and allowed Mendeleev to predict the discovery to new elements by finding and placing gaps in the table where there was a jump in atomic weight.
Moseley used the x-ray wave lengths of the elements are arranged them in a table using the experimental data. This new technique resulted in some differences in the two tables like argon and potassium switching paces. cobalt was placed before nickle and tellurium was before iodine.</span>

I may be wrong but I think it’s the second one. They speed up reactions, and there’s a certain enzyme for a certain reaction.
Answer:
Two European men and two Polynesian women settled on a previously uninhabited tropical island. All four of the settlers have brown eyes, a dominant trait, but one of the Europeans is heterozygous and carries the recessive gene for blue eyes. No new settlers arrive,and nobody leaves the island.After a few generations,the percentage of blue-eyed individuals increases from the original zero to 25 percent.This is probably due to which of the following factors?
genetic drift
Explanation:
Genetic drift entails when there are changes in the gene frequency which occur in a gene that is existing. From the analogy above, it is a known fact that only gneetic drift could allow such to happen as mutation will only occur with a sudden change of gene which is not the case described above
