Answer:
In the haploid cell, only one pair of sister chromatids are present, whereas in the diploid cell, two pairs of sister chromatids are present.
Explanation:
Chromosomes with their sister chromatids become visible during prophase. A haploid cell has only one complete set of chromosomes while there are two complete sets in a diploid cell. Therefore, prophase in a haploid cell would show the presence of only one pair of sister chromatids for each chromosome. This cell would not have the homologous pair with two pairs of sister chromatids.
On the other hand, the diploid cell would have two homologous chromosomes for one homologous pair. Each of the chromosomes of a pair would have two sister chromatids. Therefore, one homologous pair would have a total of four chromatids or two pairs of sister chromatids.
The correct answer is - one-half.
In the past century, the deforestation of the rainforests in the world had been devastating, and it is estimated that approximately one half of the tropical rainforests have been destroyed.
The reason for the large scale destruction of the rainforests is mainly because of clearing space for agriculture and for spaces where the cattle can graze. Unfortunately, the people that live the regions where the tropical forests are, are not well educated as to how to manage the land, and a big problem is that the soil of the rainforests is only good for 2-3 seasons, because it spends and erodes very quickly. Because of that, people just continue to clear more and more of it, thus leaving destroyed forest and destroyed soil behind them, without taking in consideration the long term effects.
