Disruptive selection events select for extreme traits.
Disruptive selection is a type of natural selection in which organisms with extreme traits are favored (such as in reproduction) over organisms with intermediate traits. This type of selection results in increased traits differences with increase in frequency of the alleles for the extreme traits. Disruptive selection can lead to the digression in a species line.
Some mutations in living species help them to adapt and help protect them from predtors
Glycolysis takes place in the cytoplasm. Cellular respiration takes place in the mitochondria.
