Biological Chemistry Flashcards
Carbonaceous chondrite
Extraterrestrial source of water that is rich and carbon and even has amino acid’s
Isotope
Variations of an element that differ in number of neutrons
Hydrogen bond
Bond between two polar molecules, such as between two water molecules
Uranium
Heaviest naturally occurring element; Forms in supernova explosions
Ionic bond
Bond that forms when an electron is completely transferred from one element to another
Cohesion
Property of water to form hydrogen bonds with itself
Volcano
Origin of water that comes from below earths surface
Nucleosynthesis
The formation of elements in the fusion of stars
Biology
The study of living organisms and their associated phenomena
Nonpolar
Covalent bond where the elements are about the same electronegativity and share electrons equally
Carbon
Element that bonds Easley with itself and other light elements on the periodic table; main element of organic molecules
Specific heat
Property of water that allows it to buffer temperature
Element
Atoms that have a unique number of protons
Polar
Covalent bonds where one element is more electronegative than the other, sharing the electrons unequally
Covalent
Bond where elements share electrons between them
Iron
Heaviest element formed from nucleosynthesis
Adhesion
Property of water that attracts other polar molecules
