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.
lipid=organic compounds commonly called fats and oils; are insoluble in water and used by cells for long-term energy storage, insulation, and protective coatings, such as in membranes
Answer:
the answer is d, nucleic acids arranged in a double helix
The answer is c. Adaptation
Adaptation is a physical characteristic that helps an organism survive in an environment. This help them survive in a natural selections.
The examples are :
- cactus that evolved to change its body structure to retain as much water as possible
- Bat that have adapted their hearing to hunt at night
Lines of longitude and latitude help people in finding locations by making the location easier with accuracy on a globe. For example if you had 90 degrees longitude west and 40 degrees latitude east. The lines in which those two intersect is the location. This makes locating very easy and this is what pilots use to travel to different locations.
