Answer:
B to recycle matter through the biosphere
Explanation:
The biogeochemical cycle describes how elements and compounds moves between the living and non-living component of the biosphere.
The cycle shows how matter which are composed of elements and compounds moves through various part of our world. In short, the cycle constantly proves that no matter is lost or destroyed. They are actually recycled. Elements such as hydrogen, oxygen, phosphorus, carbon, nitrogen are constantly being recycled as no new ones are formed. The biogeochemical cycle provides a vivid explanation as to why this occurs.
Stamens are the male reproductive parts of flowers<span>. A stamen consists of an anther and a filament. The pollen consists of the male reproductive cells; they fertilize ovules.</span>
The answer to this question is B
If the base-pairing in DNA becomes non-complementary such that purine bases can pair with one another and pyrimidine bases can pair with one another, the 1:1 ratio of purine to pyrimidine bases in DNA will no longer hold.
Due to the complementary base-pairing rule, the ratio of purine to pyrimidine bases in DNAs is usually 1:1. This is because Adenine always pairs with Thymine while Guanine always pairs with Cytosine.
Once this base-pairing rule is removed and becomes purine-purine and pyrimidine-pyrimidine pairings, then it becomes unnecessary for the ratio of purine to pyrimidine bases to be 1:1.
