Mitochondria and chloroplasts likely evolved from engulfed prokaryotes that once lived as independent organisms.
(At some point, a eukaryotic cell engulfed an aerobic prokaryote, which then formed an endosymbiotic relationship with the host eukaryote, gradually developing into a mitochondrion. Eukaryotic cells containing mitochondria then engulfed photosynthetic prokaryotes, which evolved to become specialized chloroplast organelles).
Microtubules play a role in the migration of chromosomes to opposite ends of a dividing cell during anaphase.
The food chain describes who eats whom in the wild.

Genetic drift
Explanation:
Genetic drift are changes that occur in the frequency of alleles in a population that are mainly due to chance. For genetic drift to occur, this change must occur randomly, and examples is usually seen mostly in small populations.
