The geological conditions.
An enormous rift in one of Antarctica’s largest ice shelves grew
dramatically over the past month, and a chunk nearly the size of
Delaware could break away as soon as later this winter, British
scientists reported this week.
If
this happens, it could accelerate a further breakup of the ice shelf,
essentially removing a massive cork of ice that keeps some of
Antarctica’s glaciers from flowing into the ocean.
Answer:
similar DNA patterns occur in closely related organisms
Answer:
Cephalization does not confer an advantage to free-floating or sea organisms. Many aquatic species display radial symmetry like the jelly fish for instance.
Aquatic animals are not cephalized because they must be able to find food, take caution and defend themselves from harm from all directions.
Changes to an organism that are a results of or results in genetic mutation alter the genetic makeup of an organism and can be passed on to the next generation.
