Can a sea star grow back a leg if it loses a leg?
A
yes
B
no
Explanation: 

Detailed explanation-1: -Regeneration. Beyond their distinctive shape, sea stars are famous for their ability to regenerate limbs, and in some cases, entire bodies. They accomplish this by housing most or all of their vital organs in their arms.

Detailed explanation-2: -Some animals are known for their ability to regrow – or regenerate – body parts following dramatic injury. Starfish are among the most famous and dramatic examples, being able to grow an entire new body from just a single arm.

Detailed explanation-3: -This replication and delocalization of vital organs makes starfish especially resilient to the loss of appendages. Following injury or amputation, a star fish can survive with its remaining organ copies during the period of regeneration, which ranges from a few months to over a year.

Detailed explanation-4: -Displays Supervisor Olivia Orchart said: “Starfish are one of the few animals in the world which are capable of not only regenerating lost limbs but also growing entirely new bodies. “As long as the lost limb has at least some of the central disc area it can develop into a second starfish.

Detailed explanation-5: -(Phys.org)-A team of marine biologists has found that some starfish lose a leg when faced with too-warm environmental conditions.
