During both meiosis I and meiosis II, cells<span> undergo the same phases found in mitosis, but the processes and results are different. Within meiosis I, homologous chromosomes become paired and crossing over occurs. Homologous pairs are separated, and the two resulting </span>daughter cells<span> have half as many chromosomes per </span>cell<span>.</span>

Answer:
Option C
Explanation:
Miller and Urey performed an experiment, using some inorganic molecules such as water, methane, carbon dioxide and hydrogen in laboratories conditions similar to early earth conditions .
Amino acids molecules formed as the result of this experiment, this proved that small organic molecules such as amino acids are formed from inorganic molecules.
Hence, the correct answer is option C
