Destroying the hearts will prevent the worm from regenerating, they said. Although we were at a very young age then, we seemed to be adept murders of earthworms.

When the earthworms go to the surface to expel their waste, to eat, or to mate, these channels become connected with the surface.
Earthworms thus cause the penetration of air into the soil.
This experiment would determine whether the penetration of air into the soil will increase the development of roots in plants. Materials and Method. This experiment was simultaneously conducted twice to minimize errors. FAD is a coenzyme in respiration and protein metabolism. The solution also contained elements like nitrogen and phosphorous.
