Answer:
Un nucleótido esta formado por una molécula de azúcar (ribosa en el ARN o desoxirribosa en el ADN) unido a un grupo de fosfato y a una base nitrogenada.
Explanation:
ADN, ARN son polímeros formados por largas cadenas de nucleótidos.
Las bases utilizadas en el ADN son: adenina, citosina, guanina y timina
En ARN, la base uracilo y ocupa el lugar de la timina.
The data supports the fourth choice, that increasing air temperature and CO2 levels correlate with a decrease in dust concentration.
The first choice is unlikely to reflect dust concentration, and is more likely to be for air temperature. The second choice is false, because the dust concentration is more of a decreasing trend. The third choice is not true, as the spikes in air temperature and atmospheric CO2 concentrations seem to occur simultaneously, implying a positive correlation.
