Answer:
"Action potential is a rapid rise and subsequent fall in voltage or membrane potential across a cellular membrane with a characteristic pattern."
It is the mode through which a neuron transports electrical signals.
Explanation:
- Option - (a) is the best choice to choose from,
- <u>The refractory period :</u>
A second action potential cannot occur until the membrane has recovered or reestablished, this is the refractory period. The absolute refractory period coincides with inactivation of voltage-gated sodium channels which makes it impossible to generate another nerve impulse.

Explanation:
Photosynthesis and cellular respiration (aerobic) are both metabolic processes that occur in specialized organnelles of living cells. These two processes are so unique to one another in the sense that one uses the product of the other as a reactant and vice versa.
Photosynthesis is an anabolic reaction that occurs in the Chloroplast of autotrophs in which captured energy from sun is used to synthesize organic food (glucose) by combining carbondioxide (CO2) and water. Oxygen is released in this photosynthetic process.
6CO2 + 6H20 --------> C6H12O6 + 6O2
Aerobic cellular respiration, on the other hand, is a catabolic process undergone by every aerobic living cell (in the mitochondria) in which glucose is broken down in the presence of oxygen to produce ATP (energy) releasing CO2 and water (H2O) in the process.
C6H12O6 + 6O2 ------> 6C02 + 6H2O
One spectacular difference is that photosynthesis uses solar energy (from sun) while aerobic cellular respiration uses chemical energy to power the process.
These primates have retained some primitive mammalian anatomical and behavioral traits, such as a strong sense of smell with an associated longer snout, eyes that are positioned more to the sides of the head, a smaller brain, a distinct breeding season and litters of offspring, nocturnal activity and the ability to synthesis vitamin C.
