WSU Biology 106 Exam 3 Questions Marking Scheme Spongocoel - ANSWER- the large central cavity of sponges. water enters the spongocoel through tiny pores called ostia and it exits through the large opening called the osculum. spongocoel is lined with choanocytes which help to create a current in the water. Spicule - ANSWER- structural elements found in most sponges. They provide structural support and deter predators. Large ones are called megascleres while microscopic ones are ca...

This document is a database Chemistry HL IA for the IB board. It investigates the effect of structural isomerism (positional, chain, and metamerism) on the boiling points of aliphatic alcohols and ethers. This can help you get a high mark for your Chemistry course especially if you are looking to do a database IA.

It contains notes on metamerism in Annelida in detail with diagrams included.
