The three main worm phyla are flatworms, roundworms, and segmented worms. Roundworms have a digestive tube that has two openings. Segmented worms have a closed circulatory system in which blood is enclosed in blood vessels. These are important steps in the evolutionary development of animals.

Which phase of cellular respiration is ALWAYS anaerobic?
Reptile [31]

Answer:

b. glycolysis

Explanation:

Anaerobic glycolysis is a catabolic route used by many types of cells for the degradation of glucose in the absence of oxygen. That is, glucose is not completely oxidized to carbon dioxide and water, as is the case with aerobic glycolysis, but fermentative products are generated.

It is called anaerobic glycolysis since it takes place without the presence of oxygen, which in other cases functions as the final acceptor of electrons in the mitochondrial transport chain, where large amounts of energy are produced from the processing of glycolytic products.
