When a small populations' gene frequencies are changed drastically by chance alone it is called a genetic drift
It increases ecosystem productivity, protects fresh water resources, and provides nutrient storage and recycling
ATP synthesization - Simple and complex lipids or carbohydrates are used to produce ATP through redox reactions. After the hydrolysis of complex carbohydrates, glucose and fructose are formed and the triglycerides are metabolized to form glycerol and fatty acids. ATP is then synthesized by oxidative phosphorylation and photophosphorylation during the energy production with in the living organisms. ATP production usually takes place in the mitochondria of the cell. The important pathways by which ATP is generated are glycolysis, the citric acid cycle (or the Kreb’s cycle), and the electron transport chain (or the oxidative phosphorylation pathway). In these three cycles of cellular respiration adenosine diphosphate (ADP) is converted to ATP and energy is released from molecules.
So white blood cell’s(WBCs for short) main job is to fight infections.
They do this by swallowing the infection.
You see,WBCs do not have a permanent shape.this means that they enlarge and decrease size of parts of their body.So they grow two long arm like structures called pseudopodia which swallow the infection.(pseudopodia means false feet).
You can see the process in the photo I attached from google
