Definition: Describing a system that contains particles of different sizes rather than all being the same size.

Example: The polydisperse solution showed a variety of particle sizes under the microscope.

Definition: A measure of how varied the sizes of particles are in a mixture or solution.

Example: The polydispersity of the sample indicates a wide range of particle sizes.

Definition: A type of electrolyte that consists of long chains of molecules, often proteins or polysaccharides, which can carry an electric charge in solution.

Example: Polyelectrolytes are used in various applications, including water treatment and drug delivery.

Definition: Relating to or characterized by the development of multiple embryos from a single fertilized egg.

Example: Some species of parasitic wasps are polyembryonic, producing several embryos from one egg.

Definition: The process where more than one embryo develops from a single egg or ovule.

Example: Polyembryony can be observed in certain species of plants and animals, where multiple embryos arise from one fertilized egg.

Definition: A type of organic compound that has multiple double bonds in its structure, typically found in long chains of carbon atoms.

Example: The chemist studied the properties of polyenes to understand their reactivity.

Definition: Relating to a type of organic compound that contains multiple double bonds between carbon atoms.

Example: The researchers studied the polyenic compounds for their potential health benefits.

Definition: A type of plastic made from the polymerization of ethylene, commonly used for making containers, kitchen items, and packaging materials.

Example: The grocery store uses polyethylene bags for customers to carry their purchases.

Definition: A type of gene that is part of a group of genes that work together to influence a specific trait or characteristic in an organism, often leading to a variety of outcomes.

Example: The height of a plant can be influenced by several polygenes working together.

Definition: The process of deriving a species or type from multiple ancestors or sources.

Example: The theory of polygenesis suggests that humans may have originated from several different ancestral groups.
