DNA only replicates once in either mitosis or meiosis. I guess you mean how many times a pair of sister chromatids are separated. Still, once for either of them. The only difference between mitosis and meiosis is that mitosis forms 2 identical daughter cells with diploid number of chromosomes in a single 'split'.
During meiosis, chromosome pairs randomly line up along each side of the cell equator. This arrangement mixes up the chromosomal combinations, which
A. helps ensure reproductive success.
B. helps create and maintain genetic diversity.
C. helps maintain all of the previous generation's characteristics.
D. helps ensure an equal number of males and females in the next generation.
The recombinant offsprings are normally the offsprings containing a combination of the parents allele, result in a genotype that differs from both parents genotype. The phenotype May be different as well although it is likely that the phenotype could be the same as the parents, as seen in the case of heterozygous dominant having the same phenotype as homozygous dominant.
Temperatures are rising world-wide due to greenhouse gases trapping more heat in the atmosphere.
• Droughts are becoming longer and more extreme around the world.
• Tropical storms becoming more severe due to warmer ocean water temperatures.
• As temperatures rise there is less snowpack in mountain ranges and polar areas and the snow melts faster.
• Overall, glaciers are melting at a faster rate.
• Sea ice in the Arctic Ocean around the North Pole is melting faster with the warmer temperatures.
• Permafrost is melting, releasing methane, a powerful greenhouse gas, into the atmosphere.
• Sea levels are rising, threatening coastal communities and estuarine ecosystems.
