Independent grouping of qualities happens amid meiosis in eukaryotes. Meiosis could be a sort of cell division that diminishes the number of chromosomes in a parent cell by half to deliver four regenerative cells called gametes. In people, diploid cells contain 46 chromosomes, with 23 chromosomes acquired from the mother and a moment comparative set of 23 chromosomes acquired from the father. Sets of comparable chromosomes are called homologous chromosomes. Amid meiosis, the sets of homologous chromosome are separated in half to make haploid cells, and this partition, or grouping, of homologous chromosomes is arbitrary. This implies that all of the maternal chromosomes will not be isolated into one cell, whereas the all fatherly chromosomes are isolated into another. Instep, after meiosis happens, each haploid cell contains a blend of qualities from the organism's mother and father.
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.
Answer:
Mantle is composed of rocks where as core is composed of metals.
Explanation:
Mantle and core both are part of the earth's crust. Though there have a difference between them- The mantle is consists of semi solidified rocks and core is consists of hot metals like iron and nickel. Core is the inner most layer surrounding the earth's center. The portion of the interior beyond the crust is called mantle. The core is the densest layer of the earth with its density ranges from 9.5-14.5 g/cm^3 where the density of mantle varies between 2.9-3.3 g/cm^3.
