Answer:
many alveoli are present in the lungs with a shape that further increases surface area. Thin walls - alveolar walls are one cell thick providing gases with a short diffusion distance. Moist walls - gases dissolve in the moisture helping them to pass across the gas exchange surface.
Explanation:
46 chromosomes, but 23 pairs.
B. New compounds with lower-energy bonds must be formed when the high-energy bonds in food molecules are broken.
Explanation:
The correct statement from the given choices is that new compounds with lower-energy bonds must be formed when the high- energy bonds in the food molecules are broken down.
Cellular respiration is classified as an catabolic process in which an energy rich substance is broken down into a lesser one.
- Metabolic processes are usually divided into catabolic and anabolic processes.
- In catabolic step, energy is broken down.
- Cellular respiration is catabolic whereas photosynthesis is anabolic.
- The new compounds formed have lower energy bonds after respiration.
