They exhibit considerable molecular complexity and diversity
C. Gases
Solids and liquids have very little space in between particles, meaning that it is hard to push the particles even closer.
Gas particles are spread apart and can be pushed together since there is more space for the air to be taken up.
c i think but im not entirely sure to be honest with you
I believe the answer for the above question is Gene pools. Gene pools are the total number of genes of every individual in an interbreeding population; contains variations in genes, the relative gene frequencies, and also the allele frequencies. Relative frequency being the average number of occurrences of a particular event in a large number of repeated units while the allele frequency of an allele compared to other alleles of the same gene in population.
