Which statement is true about oxygen and nutrient levels of rivers? TIMED TEST

Biology
1 answer:
spayn [35]3 years ago
5 0

Answer:

fast moving mountain streams which flow over rocks and waterfalls are high in oxygen due to the amount of surface area of the water that is exposed to the air.

Fast moving mountain streams are high in nutrients. Organisms have adaptations to hold on in fast moving water, resulting in a large diversity organism.

Slow moving flood plain rivers are high in oxygen due to the amount of surface area of the water that is exposed to the air.

Slow moving flood plain rivers are low in nutrients. These rivers move too slow for plant growth and other organisms to survive.

When a code does not exist that accurately describes the procedure/treatment, the coder should report ____?
zavuch27 [327]

Answer;

-Unlisted code

Explanation;

-When a code does not exist that accurately describes the procedure or treatment, the coder should report an unlisted code.

-Unlike other CPT codes, unlisted codes do not describe a  specific procedure or service. Relative value units are not assigned to unlisted  codes because the codes do not identify usual procedural  components or the effort/skill required for the service.

-Therefore; When using an unlisted code it is necessary to provide  specific information regarding the procedure(s) identified  by the code.
