The correct answer is: segmentation.
Segmentation is the fact that some animals and plants have parts of the body that are divided into segments, which typically have a similar structure (they are then called repetitive segments).
Humans also have a segmentation, for example in their spine.
Carbohydrates are the main energy source. But lipids are used for storing energy so
The entire process of manufacturing energy is known as oxidative phosphorylation, which takes place in the mitochondria, where ATP synthase enzyme is situated in the inner mitochondrial membrane and the F1-component protrudes into the mitochondrial matrix.
In the process, ADP combines with a phosphate to produce ATP. The energy liberated due to the hydrolysis of ATP into ADP is utilized to do cellular function, generally by coupling the exergonic reaction of the hydrolysis of ATP with the endergonic reactions.
The synthesis of ATP from ADP and Pi is an endergonic reaction with positive delta G.
Natural selection: organisms with certain inherited traits that are more likely to survive and reproduce than others.
These favorable traits can give an organism an advantage by giving them a higher chance of survival and reproduction. Darwin called this, "survival of the fittest"
