Answer:
The practice is knows as endogamy
Explanation:
Endogamy is a practice that has been carried out, even since the time of the Egyptians, which sought to preserve the dynasty and purity between different races and castes. This practice, although sometimes it achieved its mission, on multiple occasions it was harmful, since genetic anomalies were presented, due to the relationship, even by members of the same family.
Answer:
respect Martha's decision
Explanation:
The process of consumer decision making involves consumers in identifying their needs, gathering information, evaluating options and afterwards making the purchasing decision. Customer strategic decision-making activity is a dynamic process which includes everything from identification of issues to post-purchase behaviors.
Customer decision is of core importance fro he business thus every business should take care of it.
The first description of the DNA (deoxyribonucleic acid)chain was done by Watson and Crick in 1953, the nucleotides that constitute the DNA are four: cytosine (C), guanine (G), timine (T) and adenine (A). When doing a model is essential to remember that cytosine ONLY joins guanine and timine only link adenine, this is due to the size and chemical properties of each molecule. Later, another related and similar and molecule was discovered, the ribonucleic acid or RNA, which also is constructed by nucleotides.
In both cases, the nucleotides are compound of 3 main components: a nitrogen base, a pentose and a phosphate. When the molecule lacks the phosphate group, is called nucleoside. Depending on the chain ( DNA or RNA) the nitrogen base derives from purine (adenine and guanine) or pyrimidine (cytosine or timine) just in the RNA instead of timine is uracil (U)
The union is established between adjacent molecules through the phosphate, while among each other through the nitrogen base-remember C=G and T or U=A. The core of each molecule is the pentose. Therefore the best representation of the molecule is attached
