Wewaii [24]

Answer:

Lophotrochozoans (it is a protostome)

Explanation:

Lophotrochozoa is a group (clade) of protostome animals, i.e. animals that undergo a developmental pattern in which the blastopore develops into the mouth. Lophotrochozoa clade includes bryozoans, annelids, molluscs, brachiopods, and platyhelminthes. Most lophotrochozoans have either a lophophore or trochophore larvae during the planktonic stage.

It has a variety of functions including regulation of the blood pressure, response to the stressful condition and increase of the metabolism of the body.

It also acts as happiness hormones along with adrenaline and oxytocin but is a major flight or fight hormone and increases the heart rate in dangerous conditions.
