A test using computerized X ray images to detect tumors is called a MRI scan,CT scan,angiogram,sonogram.
Answer: Gas exchange that occurs at the level of the tissues is called internal respiration. The correct option is C.
Explanation:
Respiration a process in living organisms involves the production of energy, with the intake of oxygen and the release of carbon dioxide from the oxidation of complex organic substances. There are about four types of respiration and these includes:
- Ventilation
- External respiration
- Internal respiration
- cellular respiration
In respiration, passive movement of gases by diffusion occurs between cell surfaces in a process called gas exchange. Without this process, oxygen cannot be taken into the cells and carbondioxide released. I hope this helps. Thanks.
