Vocab test 1 Flashcards
evolution- explains diverstiy
(defined most succinctly as changes in the genetic structure of a population over time
adaptations
(adaptations are traits that help an organism survive in its current environment)
natural selection
adapts life to the environment, is a process by which a population becomes better adapted to its’ environment over time, means by which evolution can occur: individuals that are better adapted to their environment are better able to survive, reproduce, and pass on their traits (their genes) to the next generation.
nat sel/ “differential reproduction”
– the best adapted individuals are more likely to reproduce than less well adapted individuals
Life
The condition that distinguishes living organisms from non-living matter. Some features of life include: order, the need for energy, growth and development, regulation of one’s internal environment, the ability to reproduce, the ability to respond to one’s external environment, and evolutionary adaptation.
biomolecules
molecules found in living organisms
polar molecule
different electrical properties on opposite ends
covalent bonds
sharing e-
cohesion
cohesion is a physical property of particles or molecules of the same substance sticking together
surface tension
resistance to disruption at the surface
specific heat
amount of E to raise temp in a unit (usually a mole)
hydrophilic
Compounds that dissolve readily in water
hydrophobic.
compounds that do not interact with water
anabolism
joining monomers to form a polymer
catabolism
polymer can be broken down into its monomers by
