________: A fundamental ability of living organisms enabling them to change from generation,becoming better suitd to their environment.
________: very simple,unicellular,asexual,and prokaryotic organisms.
_______: The scientific study of all living things.
_________: The entire network of life on earth; the region of earth in which living organisms can be found.
_______ _________: A time of life during the Cambrian period.
___: The double stranded molocule,present in all living cells,that contains the genetic information used to form and maintain the cell and passes that information to offspring cells.
________:Cells more complex than prokaryotes, with distinct membrane- bound organelles (such as mitochondria) and a nucleus that protects the cell’s genetic material.
________:Change over time.
______ ____:A carbon- based material such as coal, oil, or natural gas that can be used as an energy source.
___________:The capacity of living organisms or cells to regulate internal conditions (for example, temperature) in order to maintain a stable state.
_-_ ________:A layer of clay in the Earth's geologic rock record between the Cretaceous period and the Tertiary period.
____:Four commonly accepted attributes of life are that it uses energy from the environment by eating or breathing or photosynthesizing (metabolism); it makes copies of itself (reproduction); over many generations it can change characteristics to adapt to its changing environment (adaptation); and it can regulate internal conditions in order to maintain a stable state (homeostasis).
_______:Warm-blooded, hairy vertebrates that grow their young inside the bodies of females and feed their young with milk from mammary glands.
__________:The capacity of living organisms to store, consume, and utilize energy through chemical reactions within cells.
_______ ________:The process by which certain inherited traits become more common in a population because they improve an organism’s chances to survive and reproduce, passing along the traits to the next generation, while other traits become less common because they decrease an organism’s chances to survive and reproduce.
_____:An organism’s role within its ecosystem; a set of traits or behaviors employed by an organism within its environment to extract food, avoid predation, and reproduce.
______________:The conversion of light energy to chemical energy, which is stored in sugars or other organic compounds, and is performed by plants, algae, and a few other organisms.
___________:Simple, single-celled organisms, including bacteria, which do not have distinct membrane-bound organelles, and in which genetic material is not bound by a nucleus.
____________:The capacity of living organisms to create copies of themselves, some of which vary slightly, leading to natural selection and evolution.
