Answer:
Release of electrons from reducing powers to O2 via four protein complexes allows release of small amount of energy at each step and makes the process energy efficient.
Explanation:
If NADH and FADH2 would reduce O2 directly, a large amount of energy would have been released in a single step. On the other hand, oxidation of these reducing powers through a series of electron carrier release a small amount of energy at each step which in turn is temporarily stored in form of proton motive force across the inner mitochondrial membrane.
Transfer of a pair of the electron to O2 pumps four protons by complex I, four by complex III and two by complex IV. The resultant proton motive force effectively stores the energy of electron transfer. This energy is then used to drive ATP synthesis.
Answer: Bees are attracted to different plants as these plants have adapted to show vibrant colors, open/flat tubular flowers, and have scents that appeal bees.
Explanation: How bees are attracted to flowers and plants is a very different world which we cannot see with our naked eye. Plants usually use their own chemicals and figures to attract bees, and bees rely on flowers for nectar and pollen. This relationship between bees and plants is very necessary for the growth of most of our food, which includes: grapes, cabbage, cherries, chestnuts, raspberries, sunflowers, strawberries, cucumber, and more. It has been an evolutionary adaption for plants to attract bees in natural ways.

Answer:
Option B) Swell
Explanation:
When runner was running he was sweating which results in loss of water from cells and cells become shrink. But at the end of marathon when he drink water his cells will gain water and store it, which results in swallowing of cells.
