Answer 1

Hey mate!

1) Urochordates are those that have notochord only in their tail of larva. Ex: herdmania, ascidia, salpa, dolilum.

2) * The taxonomic richness concerning species composition in diffeterent biotopes is biotopical diversity.

* A mule is the result of mating between a male donkey and a female horse.

3) Amphibians have a moist skin that can be easily dehydrated because of the absence of exoskeleton. But they can still overcome this, by living in moist areas and depending on water. Also, their endoskeleton is strong to compensate the absence of exoskeleton.
