Answer: O C. The shapes of the alveoli and the capillaries increase the surface area of the membranes.
Explanation:
Alveoli are tiny air sacs in the lungs, which takes the oxygen inside them. The membranes of the alveoli and the capillaries expand to take up the oxygen whereas the contract or becomes narrower when they expel out the carbon dioxide gas. Thus the shapes of the membranes of the alveoli and capillaries play an important role during exchange of gases.

The answer is <span>D.regeneration</span>
The Calvin Cycle is characteristic for photosynthetic organisms. It consists of three phases - carbon fixation, reduction, and regeneration. In the second phase, reduction, 3-phosphoglyceric acid (PGA) is reduced to glyceraldechide-3-phosphate. Further, in the third phase, regeneration, some of G3P are removed from the Calvin Cycle to be converted to glucose and other carbohydrates.
Answer:
First, third, and fifth are the answers. Glucose is broken down into carbon dioxide and water. Light energy is absorbed by chlorophyll. Energy is used to convert carbon dioxide and water into sugar.
