Chordate classes that have 3 chambered hearts?
The chordate classes that have 3-chambered hearts are Amphibia (the amphibians) and Reptilia (the reptiles). Humans and other mammals (birds too) have a four-chambered heart (left atrium, right atrium, left ventricle, right ventricle). Reptiles and amphibians have a left atrium, a right atrium, but only one ventricle (although the ventricle of reptiles has a small internal wall that divides it to some extent).

What is the body plan of an invertebrate Chordate?
The body plan of an invertebrate Chordate is quite unique as it does not entail a backbone. It has a hollow dorsal nerve cord and post-anal tail among other crucial features.
Which chordate groups can regulate their body temperature?
Among chordate groups, birds and mammals are the primary groups that can regulate their body temperature through endothermy, maintaining a constant internal temperature regardless of external conditions. Some reptiles and amphibians exhibit behavioral thermoregulation, adjusting their body temperature by changing their environment, but they are not true regulators like birds and mammals. Fish and most other chordates are ectothermic, relying on external heat sources to regulate their body temperature.
