<h3><u>Answer;</u></h3>

Sunspots

<h3><u>Explanation;</u></h3>
  • Sunspots are areas on the surface of the sun that occurs in pairs since each is one side of a loop of the sun's magnetic field which reaches the surface of the sun.
  • <u>Sunspots are cooler and darker than the rest of the Sun's surface and are marked by intense magnetic activity.</u>
  • Sunspot are created by the strong, dense magnetic fields that are generated by circulating plasma which become entangled and surge through the photosphere.

sweet [91]

Answer:

The correct option is;

B. Designing experiments to replicate the conditions in which life may have first evolved on Earth

Explanation:

The proof to the hypothesis that life originated from inanimate inorganic, or non-living  molecules which is an explanation for the origin of life on Earth was provided by an experiment designed and performed in 1953 by Stanley L. Miller and Harold C. Urey which consisted of using chemicals proposed in the hypothesis and combining them through a specific design process to replicate expected atmospheric condition before the life began on Earth.

With such successful design of experiments to replicate the conditions in which life may have first evolved on Earth, it was possible to better explain the hypothesis that life originated from inorganic molecule.
