Answer:
During Photosynthesis, Sunlight energy is used to break water down into oxygen and hydrogen
Explanation:
광합성 과정에서 햇빛 에너지는 물을 산소와 수소로 분해하는 데 사용됩니다.
Widened margins does not occur at the continental margin
Evolve is a term used to describe how one thing changes and become a higher form of itself so by saying that a multicellular change occurred from a unicellular change Then the correct term would be to say that it evolved
A Non-mutagenic factor listed in the options is : ( B ) Drinking water
<h3>Mutagenic factor </h3>
Mutagenic factors are chemical elements or various forms of radiations such as X-rays, UV rays, Sun rays, which may cause a permanent and heritable changes ( mutations ) in the DNA, when exposed to these mutagenic factors.
Hence we can conclude that a Non-mutagenic factor is Drinking water

Answer:
Explanation:
During mitosis, the chromosomes are distributed equally in the resulting chromosome. The chromosome number was doubled in the S phase of the interphase and the cell is ready for mitosis. The chromosomes are more condensed and twisted in prophase. It is also double in length. During the metaphase, the chromosomes are arranged in the metaphase plate. The microtubules from the centriole attach to the centromere of each chromosome and pull them towards the pole.
Thus each chromatid pulls apart and migrates towards the poles. The nuclear membrane and nucleus disappear during mitosis. At the end of telophase, the daughter cells contain an equal number of chromatids as in the parent cell.
Sometimes the microtubules of centrioles do not function properly and fail to pull the chromosomes equally to the cells. Thus one of the daughter cells contains more chromosomes and another fewer chromosomes. This occurs in anaphase. This results in the non-disjunction of chromosomes.
Sometimes centromere splits transversely instead of longitudinal division. This results in the formation of 2 daughter chromosomes of unequal length. This is called the isochromosomes.
The number of chromosomes distributed in the daughter cells results in a normal cell or any genetic disorder. The main function of mitosis to produce daughter cells having an equal number of chromosomes present in the parent cell.
