A mixing basin in a sewage filtration plant is stirred by amechanical agitator with a power input W F L/T. Other parametersdescribing the performance of the mixing process are thefluid absolute viscosity F T/L2, the basin volume V L3,and the velocity gradient G 1/T. Determine the form of thedimensionless relationship.

New phenotype so were seen when mating with very similar phenotypes- MUTATION 2. Only care about hereditary mutation Look at table on 3rd slide Types of mutation: Point o Can alter amino acid sequence OR change to stop codon Insertion Deletion Gene duplication Inversion Chromosome fusion Genome duplication They can happen on all different levels Viscacha Rat- Tympanoctomy Only tetroploid mammal Mutation as an Agent of evolution Which are inherited o Somatic or Reproductive A number of hereditary changes in o DNA o Chromosomes #, forms structure DNA: replication (every mitotic event is a potential mutation event o Genome size- haploid 3Mb Transposable elements o Jumping genes Estimates of Mutation Rates Phenotypic effects o Loss of function mutation- inactivated a gene o Or produces dramatic change Indirect Methods o #bp diff amount closely related species Increase due to: o Complexity o Metabolic rates o (Not independent of one anotheR) Males have 10-20x more mutations than females o Why Oocyte attrition o
