MariettaO [177]

- "This energy is usually in the form of low-level thermal energy. It is only possible to extract work when there is a temperature difference, so low-level thermal velocity; this means that the force of friction and the applied force are equal in magnitude."

- "An energy transformation is the change of energy from one form to another. Energy transformations occur everywhere every second of the day. There are many different forms of energy such as electrical, thermal, nuclear, mechanical, electromagnetic, sound, and chemical."

This animal has a protostome developmental pattern and a trochophore larva. Identify the major clades that this animal belongs t
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. A trochophore larva is a marine planktotrophic larva with several bands of cilia that form the locomotory organ (i.e., the prototroch), which is only found within the Lophotrochozoans.
