Answer:
1) Crossing over
2) Independent assortment.
Explanation:
Gametes are formed resulting from the process of meiosis where the gametes get half of the original number of chromosomes. One phenomenon that happens during the prophase 1 of Meiosis and leads to the genetic diversification is crossing over. In this process , Here, homologous chromosomes pair up and exchange information present on genes from one another. When information is exchanged, it leads to the diversity of genetic data.
The second way of increasing genetic diversity is independent assortment that takes place during metaphase 1. In this process chromosomes from both father and mother cells align on equatorial plate of the cell in an independent manner. This means that some gamete can have 1 of many different chromosomal combinations.
This reshuffling of chromosomes during independent assortment enhances the genetic diversity of any organism and this also explains why kids of same parents can look or behave very different.

Explanation:
The new research carried out by NASA on mars suggets that many of the Mars' ancient channel have been carved by flowing water, were actually formed by melt water beneath glacial ice sheets. The rocks looked familiar to the rocks found on Earth in these water channels. Moreover, conglomerate rock was found near the base of the channel on Mars.
C is what i think is correct.
Fermentation can be defined as the process that involves partial breakdown of sugar molecules into alcohol and lactic acid, in the absence of oxygen. It occurs in many bacterial cells, yeasts, and starved muscle cells. Whereas respiration involves complete breakdown of sugar molecules into carbon dioxide and water, in the presence of oxygen. It occurs in all living organisms. Respiration provides a large amount of energy as compared to fermentation as respiration produces 36 ATP molecules and 2 ATP molecules per glucose molecule.
Hence, the correct answer is 'option C - cellular respiration produces more ATP molecules than fermentation.'
