Micelles are spherical structures formed by the self-assembly of amphiphilic molecules in a polar solvent, typically water. The hydrophobic tails of these molecules point inwards, forming a core, while the hydrophilic heads point outwards, interacting with the surrounding water.

Corrosion is the gradual deterioration of a material, usually a metal, due to a chemical reaction with its environment. It often involves the oxidation of the metal, leading to the formation of oxides, hydroxides, or other compounds.

Addition reactions are chemical reactions where two or more molecules combine to form a larger molecule, without the loss of any atoms. The reaction typically involves the breaking of a double or triple bond and the formation of new single bonds.

Regeneration is the ability of an organism to regrow lost or damaged body parts. Budding is a form of asexual reproduction where a new individual develops from an outgrowth or bud on the parent organism.

Sex determination in humans is primarily determined by the presence or absence of the Y chromosome. Individuals with a Y chromosome (XY) are typically male, while those without a Y chromosome (XX) are typically female.
