Which statement best explains why invertebrates regenerate lost tissue more readily than most vertebrates do? 

biology biodiversity and its classifications life introduction to plant kingdom classification of organisms

  1. Invertebrates contain specialized cells that produce the hormones necessary for this process.

  2. Invertebrate cells exhibit a higher degree of uncontrolled cell division than vertebrate cells do.

  3. Invertebrate animals reproduce asexually, but vertebrate animals reproduce sexually.

  4. Invertebrate animals have more undifferentiated cells than vertebrate animals have.

Show answer
Correct Option: D
Explanation:
Invertebrate animals have more undifferentiated cells than vertebrate animals have, which explains that they regenerate lost tissue more readily than most vertebrates. Invertebrates, animals without a backbone, such as an earthworm, are simpler than vertebrates, such as a human. Therefore, their cells are not as complex and they may be able to regenerate or grow lost body parts easier than a more complex animal. 
Therefore, the correct answer is option D.
