The average radius of a molecule of Iysozyme, an enzyme in tears, is 1430 pm.
The size of an element's nucleus and also the total number of electrons around it grow with an element's atomic number. The radius of an atom increases with increasing atomic number.
The calculation of conversion of radius is shown below:
It is known that, 1 meter is equal to 10¹² picometers.
We can use a conversion fraction to convert 1430 picometers to meters.
1430 pm × (1 m / 10¹² pm) = 1.430 × 10⁻⁹ m
1 meter is equal to 10⁹ nanometers.
Now, use a conversion fraction to convert 1.430 × 10⁻⁹ meters to nanometers.
1.430 × 10⁻⁹ m × (10⁹ nm/1 m) = 1.430 nm
Therefore, the radius of nanometers will be 1.430nm

DDT was one of the first chemicals in widespread use as a pesticide. Following World War II, it was promoted as a wonder-chemical, the simple solution to pest problems large and small. Today, nearly 40 years after DDT was banned in the U.S., we continue to live with its long-lasting effects:
Answer:
hemoglobin
Explanation:
molecules has four blinding sights for oxygen molecules
No, because “free” nitrogen is not combined with other kinds of atoms.
Most organisms can use nitrogen only once it has been "fixed" or combined with other elements to form nitrogen-containing compounds.
