Answer the following question given this paragraph: Internal Respiration Internal respiration is gas exchange that occurs at the level of body tissues (Figure 22.23). Similar to external respiration, internal respiration also occurs as simple diffusion due to a partial pressure gradient. However, the partial pressure gradients are opposite of those present at the respiratory membrane. The partial pressure of oxygen in tissues is low, about 40 mm Hg, because oxygen is continuously used for cellular respiration. In contrast, the partial pressure of oxygen in the blood is about 100 mm Hg. This creates a pressure gradient that causes oxygen to dissociate from hemoglobin, diffuse out of the blood, cross the interstitial space, and enter the tissue. Hemoglobin that has little oxygen bound to it loses much of its brightness, so that blood returning to the heart is more burgundy in color. Considering that cellular respiration continuously produces carbon dioxide, the partial pressure of carbon dioxide is lower in the blood than it is in the tissue, causing carbon dioxide to diffuse out of the tissue, cross the interstitial fluid, and enter the blood. It is then carried back to the lungs either bound to hemoglobin, dissolved in plasma, or in a converted form. By the time blood returns to the heart, the partial pressure of oxygen has returned to about 40 mm Hg, and the partial pressure. Q: Internal and external forms of what life process occur as simple diffusion due to a partial pressure gradient? A:
****
A: respiration

OPTIONS:
- depth and gravity
- time and temperature
- temperature and density

Problem: OPTIONS:
- in mountain ranges
- at ocean bottoms
- in coastal areas
- at plate boundaries
Q: Answer the following question given this paragraph: Most geological activity takes place at plate boundaries. But some activity does not. Much of this intraplate activity is found at hot spots. Hotspots are plumes of hot material that rise through the mantle. Hotspot volcanoes erupt when the hot material melts to create magma. Q: Where does most geological activity takes place? A:
Answer:
at plate boundaries
