One variation could be that a similar but different species of worms comes to mate with the original set of worms and their offspring are longer than the original set but shorter than than the second. All the worms including the new ones then mate with each other, increasing the gene pool.

Hope this helps :)

Korvikt [17]

Answer:

The correct answer is option c.

Explanation:

Entropy is illustrated as a thermodynamic quantity that demonstrates the thermal energy that does not possess the tendency to get transformed into mechanical work.  

At the time of perspiration, the entropy of the body diminishes because of the evaporation of the water that discharges energy from the body and permits the cooling effect to take place. On the other hand, the entropy of water upsurges as the molecules of liquid converts into vapor form, which captivates larger space in the environment.
