In the histologic. specimen of loose irregular fibrous connective tissue stained with methyl blue pyronin one can see that some cells contain pyroninophilic cytoplasm, and close to the nucleus in each of the cells there is clearing? What do we call those cells? What function does it perform?

Whenever diploid populations are in hardy-weinberg equilibrium at a particular locus a) the allele's frequency should not change from one generation to the next, but its representation in homozygous and heterozygous genotypes may change. b) natural selection, gene flow, and genetic drift are acting equally to change an allele's frequency. c) this means that, at this locus, two alleles are present in equal proportions. d) the population itself is not evolving, but individuals within the population may be evolving.
