Web1 hour ago · Every cell in our body contains a vibrant population of mitochondria, or, more precisely, of mitochondrial DNA molecules (mtDNAs). Just like members of any population mtDNAs multiply (by replication) and die (i.e., are removed, either by degradation or by distribution into the sister cell in mitosis). An intriguing question is whether all … WebBy dividing the area into (invisible) quadrats, and counting the number of organisms per quadrat, we can assess the mean and variance of the number of organisms per quadrat, and thereby have a quantitative basis for deciding whether the observed dispersion is best described as random, uniform or clumped .
