Although we think of land when we hear the word biome, there are also aquatic biomes. The abiotic factors that influence life forms vary with location within ocean systems. Oceanographers divide the ocean into five broad vertical zones as seen in the chart above. Compare the characteristics of the five zones. The giant tube worms, Riftia pachyptila, pictured here, have a red "plume" at the tip of their free end which is an organ for exchanging compounds with the environment. The tube worm does not have many predators. If threatened, the plume may be retracted into the worm's protective tube. The plume provides essential nutrients to bacteria living inside the worm. Tube worms have no digestive tract, but the bacteria, which may make up half of a worm's body weight, convert the oxygen, hydrogen sulfide, carbon dioxide, taken in by the plume, into organic molecules on which their host worms feed. Compare this information with the information in the chart. Where could these worms live?

the oxygenated blood then leaves the lungs through pulmonary veins, which return it to the left heart, completing the pulmonary cycle. this blood then enters the left atrium, which pumps it through the mitral valve into the left ventricle. from the left ventricle, the blood passes through the aortic valve to the aorta.

deoxygenated blood leaves through the right ventricle through the pulmonary artery. from the right atrium, the blood is pumped through the tricuspid valve (or right atrioventricular valve), into the right ventricle.

the dna molecules have a negative charge because of the phosphate groups in their sugar-phosphate backbone, so they start moving through the matrix of the gel towards the positive pole. power is turned on and dna fragments migrate through gel (towards the positive electrode).

explanation:

answer;

-phase iii

explanation;

phase three begins with the transition of a recovered individual to a phase three team of the appropriate service. this phase usually takes place at a military medical facility in the united states. one of the goals of phase three is family reunification.
