Vadim26 [7]3 years ago
8 0

Answer:

Explanation:

It is important that a cell undergoes replication before cell division occurs because, the main goal of cell division is to make more cells. And for all these cells to remain functional, all their components must be intact and complete. without this, these cells might not function. Thus, the goal of replication is to produce the next new copy that would go into one of the daughter cells produced. With DNA replication, the set of DNA present in a cell can be duplicated and then each daughter cell that results from division can have its own entire set of DNA and then cell division can theoretically continue as normal indefinitely.

  • The testes occur along the whole body.
  • Planaria originally have habitats in dark, murky water which results in such sensitivity .
  • They are also sensitive to other stimuli such as chemical gradients, vibration, magnetic and electric fields .
  • Their central nervous system includes the anterior (head, brain and eyes) and middle (abdominal trunk and pharynx).
