Question

read the newsela article on common types of asexual reproduction to answer the following question
regeneration, as seen in echinoderms, is best described as:
growth of a new individual from a detached part of the parent
merging of two cells into one
division of a cell into two equal parts
laying of unfertilized eggs

Explanation:

Regeneration in echinoderms (like starfish) involves a detached part (e.g., an arm) growing into a new individual. Merging two cells is not regeneration. Cell division into two equal parts is binary fission (a different asexual reproduction type). Laying unfertilized eggs is parthenogenesis (another asexual reproduction type).

Answer:

Growth of a new individual from a detached part of the parent.
