Answer:
Sodium chloride removes proteins from DNA and helps in DNA precipitation.
Explanation:
The Deoxyribonucleic acid (DNA) is negatively charged due to the highly polar phosphate groups that make up the phosphate backbone. The molecules of water are also highly polar and they have positive charge, thereby water molecules interact with the negative charges of the DNA. The sodium chloride generates temporary attraction forces between sodium (positive) ions and the DNA backbone (negative), thereby DNA can be disassociated from the aqueous layer. Moreover, sodium chloride helps to remove proteins (histones) that bound to DNA and also helps to maintain proteins in the aqueous layer.

The Vital Capacity is the maximum volume of air that can be exhaled after taking the deepest breath possible.
Breath is the inhalation or exhalation of air for maintaining the gaseous exchange. Inhalation is taking the air (for oxygen) inside the lungs. Whereas exhalation is the removal of air (of carbon dioxide) outside the lungs.
Vital Capacity can also be denoted as VC. Mathematically, it is equal to the sum of Inspiratory Reserve Volume, Tidal Volume, and Expiratory Reserve Volume. The volume of VC is approximately 4800 mL. However, the amount can vary according to the age and health of a person.

Answer:
1.183×10∧-4 m³
Explanation:
ρ=m/V
Here, m=0.304kg
ρ=2.57g/cm^3 =2570kg/m^3 [1g/cm^3=1000kg/m^3]
V=1.183×10∧-4 m³
Hope, this helps you.
