Sea stars encounter predators and underwater currents that can dismember their bodies. When a sea star loses an arm, the separated limb can grown into a new sea star. What processes make this possible? 1. sexual reproduction
2. meiotic cell division
3. asexual reproduction
4. degenerative division

answer:

sequence 1- deletion

                  2- duplication

                  3- insertion

                  4- substitute

                  5- inversion

here is the answer

water, ice, acids, salts, plants, animals, and changes in temperature are all agents of weathering. weathering is the breaking down or dissolving of rocks and minerals on earths surface. once a rock has been broken down, a process called erosion transports the bits of rock and minerals away.
