Explanation:
Robins are born in the spring or summer and are mature birds and ready to breed in the following spring or summer. They do not mate for life. Pairs usually remain together during an entire breeding season, which can involve two or three nestings. However, in spring, sometimes a male and female who mated the previous year will both return to the same territory and end up together for another year. This happens most frequently when they were successful raising babies the previous year. Robins lay one egg per day, for a total of 5–6 eggs in a clutch. The eggs hatch about 12 - 14 days after the last egg was laid. Baby robins jump from their nest when they are about 13 days old, but the range is 9 - 16 days. After leaving the nest (fledging), it takes another 10-15 days for babies to become strong fliers and independent birds. The parents continue to feed their young during this period.
Most robins die their first year. But the lifespan goes up dramatically for the ones that survive this critical time, because they've learned so many important life skills. Of those that survive their first year, most wild robins live to be about 5 or 6. As of February, 2001, the longest-living banded wild robin ever recorded had survived 13 years and 11 months, according to the Bird Banding Laboratory at the Patuxent Wildlife Research Center. In captivity, robins have survived longer than 17 years.

Explanation:
NORs (Nucleolus organizer regions) are chromosome regions in which ribosomal genes are encoded, while nucleoli (singular = nucleolus) are nuclear territories where ribosomes are produced and assembled. A nucleolus may contain one or more NORs.
Nucleoli are composed of DNA, RNA and proteins arranged around NORs.
The transference RNA (tRNA) genes are known to be spatially associated with the nucleolus as happen, for example, in <em>Saccharomyces cerevisiae</em>.
According to the levels of organization in a multicellular organism.
human being --> digestive system --> stomach --> stomach lining tissue --> stomach lining cell.
<h3>What do you mean my level of organization? </h3>
LEVEL OF ORGANIZATION:
Living organisms are classified according to hierarchical levels. The hierarchy of the level of organization is as follows:
cell → tissue → organ → organ system → organism
Thus, option "B" human being --> digestive system --> stomach --> stomach lining tissue --> stomach lining cell.
