Answer:

Ernest Rutherford.

Explanation:

Ernest Rutherford was a British physicist and one of the greatest experimentalists. He "gave birth" to nuclear physics. He lived from 1871 to 1937.

In 1911, he performed many experiments in order to discover and explore radioactivity. In one of his experiments he discovered that the atom has a positive center charge that contains most of atom's mass. He called that nucleus the proton, after the greek word "protos" which means "first". Different number of protons can be found in the atoms of different elements, which gave their nuclei different charges. That is how he established that the hydrogen nucleus was an elementary particle.

Kisachek [45]

The correct answer to this open question is the following.

Although there are no options attached, we can say the following.

The best soil for agriculture in Mesoamerica was found in the southern highland valleys. The soil had been enriched through volcanic eruptions, while the mid climate made the area an ideal place for people to settle.

This is completely correct, Volcanic eruptions produced ash that spread throughout the Mesoamerican region.

Let's have in mind that Mesoamerica (modern-day México) was a region with major volcanoes in the area. The highest peak in México is the volcano "Citlaltepetl," better known as "Pico de Orizaba"(Orizaba Peak). Then, we find two impressive volcanos that divide the state of México and México City with the state of Puebla: the impressive Popocatepetl and the Iztazihuatl.

These volcanoes were very active in Mesoamerican/Precolumbian times and allowed Native Indians to grow quality cash crops.
