What are the major classes of lipids​
PolarNik [594]

Answer:

phospholipids, sterols, and triglycerides

Phospholipids make up the outermost layer of cells in the bodies of both animals and humans. They create a protective layer around the cells to help maintain them.

Which of the following pairings of phylum and description is incorrect? A Echinodermata—bilateral symmetry as a larva, coelomate
Flura [38]

Answer:

Porifera—gastrovascular cavity, coelomate.

Explanation:

Sponges do not contain digestive system but obtain nutrients through the diffusion process. Porifera is the most commonly asymmetrical in nature but can also have radial symmetry. Porifera has no coelom.

Lacking a true digestive system, they depend on the intracellular digestive processes of their choanocytes for their energy intake. Gas exchange, circulation, and excretion occur by diffusion between the water and the cells.
