Capillary Action - Attractive forces (H-bonds) allow water to "climb" up tubes against the force of gravity because of this property., Polarity - Positive & negative charges on the ends of water make it attract and repel other substances. The positive hydrogen and negative oxygen cause this property., Ecosystem - A community of living things along with their natural environment., Population - All the organisms of a certain kind in a particular place or defined region., Adhesion - Water molecules stick or cling to OTHER substances. This property is also why water soaks into objects., Cohesion - Water molecules stick to each other to form droplets because of this property., Universal Solvent - Water can dissolve many different substances allowing organisms to transport nutrients and get rid of wastes, this make it a _______________________ ____________________., Surface Tension - The attractive forces (H-bonds) of water at the surface of a liquid can be quite strong allowing insects to walk on it like water striders do., Carbohydrate - An organic molecule containing hydrogen, carbon, and oxygen that acts as a major quick source of energy in an organism's diet., High Specific Heat - Water can moderate climates and resist large changes in temperature because of this property., Lipid - A fat that is used as a long term source of energy in living organisms., Solute - A substance being dissolved into another substance., Protein - A molecule composed of a chain of amino acids that act as an essision building block of muscles, skin, bone, hair, and other body structures., Abiotic - A nonliving part of an ecosystem that shapes its environment., Cascade Effect - A chain of events that occurs when an event in a system has a measurable impact on other related systems., Biosphere - The region of Earth that is occupied by living organisms., Amino Acid - An organic molecule that contains a carboxyl and an amino group that combines to form proteins., Trophic Levels - A position in a food chain, food web, or ecological pyramid.,
