a cranium and vertebrae, but no jaws or paired fins

Explanation:

Lamprey belongs to a group of jawless vertebrates known as agnatha. In addition to being jawless, they posses a structure known as notochord which is a general feature of all vertebrates. The notochord however, is surrounded by cartilage-like vertebral column. The also posses brain which is usually housed in a cranium.

Lamprey posses no paired fins unlike other fishes. The notochord helps the to move as well s supports their bodies.

Hence, if Haikouichthys lanceolata is similar to lamprey, it will probably posses a cranium and vertebrae, but no jaws or paired fins just like lamprey.

explanation:

while the heads of the phospholipid structure attract water, the tails are hydrophobic. the model shows how the hydrophilic section folds around the fluid molecules to bring them into the cell so they don’t need to pass through the hydrophobic tails.
