Organisms that inhabit intertidal zones must be able to tolerate radical changes in temperature, salinity, and moisture and also be able to withstand wave shock. Intertidal zone is the coastal area alternately exposed and submerged by tides. Tide pool animals and plants are well adapted to the intertidal zones. Some adaptations include; the ochre sea star can tolerate a longer time period exposed to air than many other sea stars. They regularly withstand up to eight hours of exposure during low tides.
DNA has to be divided into the two nucleotide chains that build it, so that new chains can be started to form. These new chains will connect with the old ones.
<span>Organisms decompose more quickly when they are in contact with oxygen. ... When an organism is buried quickly, there is less decay and the better the chance for it to be preserved. The hard parts of organisms, such as bones, shells, and teeth have a better chance of becoming fossils than do softer parts.
