The level that is used in nuisance contaminations that are
present and requires the lowest form of chemical or respiratory protection is
the level d. This level requires use of protection that are only minimal such
gloves, booths, safety glasses, mask or shield.
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

The S Phase of Interphase
The S phase of a cell cycle occurs during interphase, before mitosis or meiosis, and is responsible for the synthesis or replication of DNA.
