It is true that the iron recommendation for girls exceeds that of boys during adolescence.
During an adolescence, girls and boys require iron for a large growth spurt and the gain of adult phenotypes and biologic rhythms.
In this period of the life, iron recommendation increase in both girls and boys, because of the increase in lean body mass, the expansion of the total blood volume, the increase and start of menstruation at girls.
Iron is essential for oxygen transport, red blood cell creation, cognitive performance and immunological function.
The overall iron requirements for girls are up to twice as boys.

Some parts of a plant can be white because they do not contain chlorophyll.
Chlorophyll is a term to refer to a characteristic compound of most plants that has the function of:
- Bring the green color to vegetables
- Take charge of the photosynthesis process.
Some plants do not have as much chlorophyll in their systems. However, this does not affect their reproduction and growth because they have developed other feeding methods through their roots.
These plants that contain low amounts of chlorophyll have pale and white colorations because chlorophyll is what gives the plants their intense green color.

Answer:
m = 50.74 kg
Explanation:
We have,
Initial temperature of water is 20 degrees Celsius
Final temperature of water is 46.6 degrees Celsius
Heat absorbed is 5650 J
It is required to find the mass of the sample. The heat absorbed is given by the formula ad follows :
c is specific heat of water, c = 4.186 J/g°C
So,
So, the mass of the sample is 50.74 kg.
