Question

1a.The mitochondria of eukaryotic cells likely evolved from bacteria because
   they share genetic similarity to proteobacteria
   they have undergone rapid mutagenesis
   they show signs of horizontal gene transfer
   they exhibit a similar structural composition

1b.What technique can be used to assess the phylogeny of most bacterial species?

Cultivation in the laboratory

    b) Microscopy and physiology
    c) 16s and genome sequencing
    d) Environmental growth conditions

   Cultivation in the laboratory
   Microscopy and physiology
   16s rRNA sequencing
   Environmental growth conditions

Answer 1

1a).

   they share genetic similarity to proteobacteria ----> TRUE (this indicates the inheritance of mitochondria from the microbes because it does not undergo recombination)

they have undergone rapid mutagenesis ----> FALSE
   they show signs of horizontal gene transfer ----> TRUE
   they exhibit a similar structural composition ----> FALSE
