The water vascular system of echinoderms (A) functions as a circulatory system that distributes nutrients to body cells. (B) fun
ctions in locomotion and feeding. (C) is bilateral in organization, even though the adult animal is not bilaterally symmetrical. (D) moves water through the animal’s body during filter feeding. 4. Which of the following combinations of phylum and description is correct? (A) Echinodermata—radial symmetry as a larva, coelom (B) Nematoda—roundworms, internal skeleton (C) Platyhelminthes—flatworms, gastrovascular cavity, no body cavity (D) Porifera—gastrovascular cavity, coelom

Explanation:
Echinoderms are marine animals. They have a water vascular system that make them able to move (locomation), respiration and food and waste transportation. This system is full of different canal along the body.
Echinodermata has not a radial symmetry as a larva, in fact it has a bilateral symmetry and coelom present. When it comes to Nematoda, they are roundworms and have a pseudocoelomate. Finally, porifera has a gastrovascular cavity and no coelom.
Explanation: Photosynthesis removes CO2 from the atmosphere and replaces it with O2. Respiration takes O2 from the atmosphere and replaces it with CO2.
During cellular respiration, a glucose molecule is gradually broken down into carbon dioxide and water. Along the way, ATP is produced directly in the reactions that transform glucose. However, more ATP is later produced in a process called oxidative phosphorylation.
The world is an illusion is the only possible answer.
Explanation:
Hindu priests do not claim to be able to spek to god, and since they are polythiestic they do not believe in one god. They do believe in a specific set of gods however so they would not believe that god is formless. They also believe in Karma and reinecarnation so ``We only live once`` would not be a viable answer either. To my knowlage ``The world is an illusion`` is not a core hindu belief either so I would question your teacher about that.
