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

Answer:
d. Genes that play a role in the same metabolic pathway are organized into an operon.
Explanation:
In prokaryotic organisms like bacteria, polycistronic mRNAs exist which means that each gene does not have a separate promoter of its own. In fact many genes are under the control of a single promoter. These genes being a part of same metabolic pathway are organized into an operon. For example, lac operon and tryptophan operon. In lac operon, three genes named as β-galactosidase, permease and transacetylase are expressed under a single promoter which is known as lac promoter.
In contrast to this, in eukaryotes the mRNAs are monocistronic i.e. only a single gene is controlled under a single promoter.
Food security is a condition of having reliable access to a sufficient quantity of affordable and nutritious food.
