conjugation has physical contact between two cells and genetic transfer
transduction has a phage
tranformation has a nascent dna extracellular uptake
a hemolyisis is incomplete blood lysis and b hemolysis is clear lysis of rbc

strept pyogenes and strept agaltiae are b hemolytic, whereas, strpt pneumoniae and viridans re alpha hemolytic
alpha hemolysis will form a green zone wheras beta hemolysis will form a clear zone
about transduction
it has a bacteriophage, viruses gen use this, they get incorporated into the bacterial genome, and then reproduce. and they can undergo a lytic cycle and a lysogenic cycle
transformation is when say a bacteria is lying in a medium and another dead cell releases its dna, which is taken in by that bact
