Answer: Human evolution, the process by which human beings developed on Earth from now-extinct primates. Viewed biologically, we humans are Hono Sapines, a culture-bearing upright-walking species that lives on the ground and very likely first evolved in Africa about 315,000 years ago.
Yes, I agree with statement b/c in meiosis I, specifically in prophase I the homologous chromosomes line and form tetrads in which they exhibit the act of ‘crossing over’ which allows for genetic diversity; This would not occur in mitosis as body cells are produced to repair or for growth so the division of cells must allow for the exact replication of DNA or it is not possible to repair the body or growth if there is genetic variation in each cell. Also, in Meiosis I, specifically when metaphase I occurs, it is impossible to predict how the homologous chromosomes will be split, therefore creating even more diversity of genes known as Independent assortment. None of these processes occur in meiosis II, as the exchange of DNA and act of genetic diversity has already occurred in Meiosis I, therefore Meiosis II simply has to go throwing regular cell division making it more similar to mitosis than Meiosis I; Independent assortment and crossing over are the processes that set Meiosis I to differ from the others.

Carbon moves from the atmosphere to the biosphere and also from the atmosphere to the hydrosphere through a variety of processes.
<h3>Carbon cycle</h3>
Carbon in the form of carbon dioxide in the atmosphere is sequestrated by plants (biosphere) through a process known as photosynthesis.
When plants die, their organic matter decomposes into the soil (lithosphere) while some carbon is released back into the atmosphere via decomposition. Soil carbon also helps plants to grow.
Carbon in the atmosphere also gets sequestrated into water bodies (hydrosphere) by dissolution.

<span>Explanation: Oxygen is the more electro-negative of the atoms in the water molecule, so it tends to pull the 'shared' electron more to itself. Thus, the oxygen atom has a greater time-share of all electrons, and therefore the hydrogen atoms are more positive for a partial lack of electrons</span>
