Difference in density is the basis of
1 Ultrafiltration
2 Molecular sieving
3 Gravity Separation
4 Molecular attraction
Explanation:
In case of ultrafiltration it is particle size of micron sizes present in liquid or gas are getting filtered. In molecular sieving, permeability of molecular sieve membranes based on the size and shape of the molecules is employed. In gravity separation difference in density of particles is employed In molecular attraction, mainly exchange of cations to anions among given two molecules. In atomic absorption ,elements are identified based on the absorption of optical radiation by free atoms in gaseous state.

Which of the following elements of matter would best convey that there is life on earth
1 Oxygen
2 Hydrogen
3 Carbon
4 Iron
Explanation:
Life on Earth is based on carbon, likely because each carbon atom can form bonds with up to four other atoms simultaneously. This quality makes carbon wellsuited to form the long chains of molecules that serve as the basis for life as we know it, such as proteins and \(DNA.\)
