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

It was harder to find jobs and less survival resources when moving to the coast. As America industrialized, the people started to migrate more towards the west especially when railroads were beginning to attach.
Answer: D. compared to men, women derive less satisfaction from work and family.
Explanation:
Depression is an emotional draining situation that is caused by events and when this happens, the psychology of individuals becomes affected and individuals involved begin to have a section dark thought pattern which could be often or rare depending on how the mood occurs. Among the options given above women don't derive less satisfaction from work and family than men. The world is evolving today and women are beginning to have interest in a lot of things especially working in the secular sector and they have also devised means to cater for their families alongside, these doesn't make them depressed but rather fulfilled doing both.
From earliest to latest, list the psychosocial crises connected to Erikson's stages of psychosocial development. vs mistrust:
<h3>Whose phases of cognitive growth are most closely related?</h3>
Each of the four stages that Piaget identified for children's cognitive development represents a different method of thinking about and comprehending the environment. He identified them as (4) formal operational thinking, (5) concrete operational thinking, (6) preoperational thinking, and (7) sensorimotor intelligence.
<h3>Which of these traits, according to Erikson's theory of psychosocial development, are present in adolescents?</h3>
The adolescent is concerned about his or her appearance and body image. A sense of identity is developed in the teenager through decision-making.
