Charcoal might look dirty, but a new trend claims it's a great cleanser for the body, inside and out. Activated charcoal has been popular in face masks and other skin cleansers for the past few years.
While all prokaryotes reproduce asexually (without the formation and fusion of gametes), mechanisms for lateral gene transfer such as conjugation, transformation and transduction are sometimes likened to sexual reproduction (or at least with sex, in the sense of genetic recombination).lonal Fragmentation in multicellular or colonial organisms is a form of asexual reproduction or cloning where an organism is split into fragments. Each of these fragments develop into mature, fully grown individuals that are clones of the original organism.
The ultimate sources of variation, the source of new heritable characteristics in populations and species, are due to mutation and recombination in chromosomes, genes, DNA. The frequency of a gene, or allele, in a population is due to number of forces: forces increasing variability, and forces decreasing variability. Forces increasing population variability. Four important allelic forces drive population heterogeneity.
