Explanation:
When the high energy electrons move from the reactive center, they are conveyed from one chain protein to another as the energy in the electrons is harnessed to pump H+ ions from the stroma into the lamellae. The electron will ultimately reduce NADP+ to NADPH and the electrons in the reactive center will be replaced by high energy electrons from the splitting of a water molecule in photolysis. The energy of the sun is used to split the water molecule. The high energy electrons then undergo the same cycle as the previous electrons and the cycle continues.
Eventually a proton-motive force is created across the lamellae membrane. This potential energy of the high H+ ion gradient is used by ATP synthase enzyme to phosphorylate ADPs to ATPs.

Answer:
rhizobia is an important nitrogen fixing bacteria found in the soil to help grwo plants like legumes. rhizobia enter into a symbiotic relationship withe legumes
Explanation:
rhizobia and legumes coexist by entering into a symbiotic association. rhizobia is a bacteria that fixes nitrogen molecules for the legumes and in return the legumes provide the bacteria with food and nutrition.
If rhizobia becomes extinct in the near future it would be difficult for plants like legumes to grow as they wouldn't get sufficient nitrogen and nitrogen is an important nutrition for the plant to grow and develop. Thus it can cause rapid depletion or death of plants that need rhizobia to fix nitrogen molecules for them.
Answer;
B. Jumping rope
Explanation;
Jumping rope is not an anaerobic exercise but an aerobic exercise.
Anaerobic exercise is a form of high intensity exercise that increase the oxygen debt. However since the muscles require oxygen to maintain prolonged exertion, anaerobic exercises can only last for short periods of time.
Examples of anaerobic activity sprinting, high-intensity interval training, power lifting and most athletic sports.
