Budha gelati combination of mothers place and significant role in determination of the sex of the newborn baby​

Answer 1

Protonephridia likely first arose as a way to cope with a hypotonic environment by removing excess water from the organism (osmoregulation). Their use as excretory and ionoregulatory structures likely arose secondarily. These are excretory systems in phyla Platyhelminthes and are also called blind tubules.
