Answer 1

Answer 1) So many phylogenetic studies have shown or confirmed that there is a sister grouping relationship between Choanoflagellates, Metazoa (animals) and fungi called to supergroup Opisthokonta.

Answer 2) Animals are described as eukaryotic because they have a true membrane-bound nucleus in their cells. Animals also called multicellular because there are so many cells made their body. Animals are heterotrophs as they derive energy from other means not produced within the body.

Answer3) Approx 5% of all animal species are Vertebrates and rest are invertebrates.
