I think, Lipogenesis is a common for organic molecules because the intermediate Acetyl-CoA is formed in most metabolic processes. Lipogenesis involves the formation of fatty acids from Acetyl-CoA. Acetyl-CoA is an intermediate stage in metabolism of simple sugars, such as glucose, which is the preferred source of energy for most living organisms.
Answer:
Natural selection
Explanation:
According to Darwin, natural selection is the mechanism through which evolution takes place. Natural selection is the mechanism through which the heritable traits characteristic changes in an organism over the generations. Variations in traits of organisms are passed down through the generations and each generation has their genes affected by the environment.
<span>The law of segregation tells us that the rearrangement of chromosomes into gametes is RANDOM.

The ileum has <span>plicae circulares</span>, villi and microvilli, that are folds and projections of the mucosa layer of the ileum, that increase the surface area of food absorption. The mucosa and the submucosa of the stomach have inner folds called rugae that increase the surface areas in which food is digested by enzymes.
Plants have root hairs in their tap roots that also increase the surface area for which they absorb water and nutrient from the soil. Fibrous roots have a mesh-like a network that also increases the surface area for increased absorption.
Photosynthesis: 6H2O + 6CO2 ----> (yields, in the presence of sunlight) C6H12O6 + 6O2
Light Dependent:
Plants break up the water (H20) into a Hydrogen and an Oxygen (O2). The Oxygen is released through the plant's stoma. The electron from the H is energized by the sun and used in the Electron Transport Chain to make ATP.
Light Independent:
Used CO2, ATP and NADPH in the Calvin Cycle (Basically moving a bunch of Carbon and rearranging it) to eventually make a Glucose molecule (C6H1206).
