Answer:
English:
RNA and DNA are polymers made up of long chains of nucleotides . A nucleotide is made up of a sugar molecule (ribose in RNA or deoxyribose in DNA) attached to a phosphate group and a nitrogen base. The bases used in DNA are adenine (A), cytosine (C), guanine (G), and thymine (T).
Spanish:
El ARN y el ADN son polímeros formados por largas cadenas de nucleótidos. Un nucleótido está formado por una molécula de azúcar (ribosa en el ARN o desoxirribosa en el ADN) unido a un grupo fosfato y una base nitrogenada. Las bases utilizadas en el ADN son la adenina (A), citosina (C), guanina (G) y timina (T).

Answer;
D. The birds have different mating seasons.
Explanation;
-Different species of birds have different mating or breeding seasons. Evolution has played a role in adjusting the timing of avian(birds) breeding seasons to maximize the number of young produced. The breeding season depends on a number of factors, for example In the temperate, subarctic, and arctic zones, the overriding factor is the availability of food. This varies across all different species of birds, irrespective of other similarities they may have.
So following the octet rule, carbon atom can only form a maximum of 4 bonds because, by then, it will have 8 valence electrons.
