Mitochrondria of the eukaryotic cells.
<span>As many researchers hypothesize that the old single-celled organism or the origin of the complex-celled organisms came from the endosymbiosis of the mitochrondrion organism and the prokaryotic cell. It has been said that mitochondria was an independent organism which then to have been evovled itself after planting itself inside a prokaryotic cell which aided cellular respiration and production of ATP (Adenosine Triphosphate). This then aided the prokaryotic cell to be more sophisticated and caused another change from having without a true nucleus to a eukaryotic cell with a nucleus and embedded DNA. <span>

Question 1) g is subduction
question 2) i think is b not 100% sorry
<span>The answer is "Meiosis".
Meiosis is a cell division process which forms four daughter cells which are different from parent cell. Formed daughter cells have half of chromosomes when compared to parent cells. Hence, Daughter cells are haploid (have single set of chromosomes). This process occurs in the sexually reproductive organisms and formed daughter cells can be either sperms or egg cells according to the gender of living being.</span>
