The separation of the sister chromatids during the cell division occurs in the anaphase in mitosis and anaphase II in meiosis.
During the anaphase in mitosis, and the anaphase II of the meiosis, the chromosomes aligned at the center of the nucleus separates and the sister chromatids of the chromosomes starts moving towards the opposite poles as the spindle fibers starts contracting.
Answer:
Salinity is the <em><u>salt concentration</u></em> in water. Oceans salinity and temperature affect density of water, Higher the salinity denser the water and Lower the temperature denser the water.
Explanation:
As we go down in the ocean , temperature goes down and denser the water.
Less dense water will be on top and higher the density will be on bottom. Warmer water will be on top.
Salinity <em> increased</em> in ocean on evaporation of sea water and formation of ice in water. Weathering of rocks , formation of soil also add minerals and salt in ocean.
Melting of snow, ice in sea, addition of river freshwater and precipitation of rain <em>decrease </em>the salinity of ocean.

Diversity and emergence of new traits (can be beneficial in some cases). Mutations are part of what drive evolution and allow for that change to take place.
Answer:
<em>The chromosome number will not be constant and the person would die.</em>
Explanation:
During gamete formation, half of the chromosomes arise from one parent and the other half from the other parent. This is possible due to the process of meiosis.
If during gamete formation, the number of chromosome does not get reduced, then after fertilization the gamete will have double the number of chromosomes as compared to the parents. Hence, the chromosome number of the person will not remain constant and he/she would die.
