Term
|
Definition
| DEOXYRIBONUCLEIC ACID. responsible for heredity and for programming the production of an organism's molecules. each species' genes are coded in the sequence of the four building blocks making up DNA's two helically coiled chains. all organisms share a set of common features: ordered structures, regulation of internal conditions, growth and development, energy processing, response to environmental stimuli, the ability to produce, and evolutionary adaptations. |

|
|
Term
| most basic chemicals necessary for life |
|
Definition
| carbon dioxide, oxygen, water |
|
|
Term
| explain how photosynthesis in plants functions in both the flow and energy in an ecosystem. |
|
Definition
| photosynthesis uses light to convert carbon dioxide and water to energy rich food, making it the pathway by which both chemical nutrients and energy become available to most organisms |

|
|
Term
|
Definition
| subdivided by internal membranes into many different functional compartments, or organelles, including the nucleus that houses the cell's DNA |
|
|
Term
|
Definition
| the units of inheritance that transmit information from parents to offspring. |
|
|
Term
|
Definition
| all living things exhibit complex organization. |
|
|
Term
|
Definition
| the enviornment outside an organism may change markedly, but mechanisms maintain an organisms internal environment within limits that sustain life. |
|
|
Term
|
Definition
| inherited information carried by genes controls the pattern of growth and development of organisms. |
|
|
Term
|
Definition
| organisms take in energy and transform it to preform all of life's activities. |
|
|
Term
| response to the environment |
|
Definition
| all organisms respond to environmental stimuli. |
|
|
Term
|
Definition
| organisms reproduce their own kind. |
|

| the term used for a particular type of organism. |
|
|
Term
|
Definition
| kingdoms of life can be organized into three groups called domains. |
|
|
Term
|
Definition
| all eukaryotic, organisms with eukaryotic cells, are now grouped into various kingdoms of domains. |
|
|
Term
|
Definition
| species living today are descendants of ancestral species. |
|
|
Term
|
Definition
| individuals in a population vary in many heritable traits |
|
|
Term
| overproduction of offspring |
|
Definition
| a population of any species has the potential to produce far more offspring than will survive to produce offspring of their own. |
|
|
Term
| unequal reproductive success |
|
Definition
| individuals are unequal in their likelihood of surviving and reproducing. thos3e individuals with heritable traits best suited to the environment will leave the greatest number of healthy, fertile offspring. |
|
|
Term
| over time, favorable traits accumulate in a population |
|
Definition
| over many generations, a higher and higher proportion of individuals will have the advantageous traits. |
|
|
Term
| how does natural selection adapt a population of organisms to its environment? |
|
Definition
| on average, those individuals with heritable traits best suited to the local environment produce the greatest number of offspring that survive and reproduce. this increases the frequency of those traits in the proplation. |
|
|
Term
|
Definition
| seeks natural causes for natural phenomena. the scope of science is limited to the study of structures and processes that we can observe and measure. |
|
|
Term
|
Definition
| The study of life. blends two main scientific approaches: discovery science, which is mostly about describing nature, and hypothesis-based science, which is mostly about explaining nature. |
|
|
Term
|
Definition
| is a proposed explanation for a set of observations. |
|
|
Term
|
Definition
| derives general principles from a large number of specific observations. |
|
|
Term
|
Definition
| is the logic used in hypothesis-based science to come up with ways to test hypotheses. reasoning flows from the general to the specific. from general premises, we extrapolate to the specific results we should expect if the premises are true. |
|
|
Term
|
Definition
| explains a great diversity of observations and is supported by a large and usually growing body of evidence. theories continue to generate new hypotheses, which can be tested. |
|
|
Term
|
Definition
| designed to compare an experimental group with a control group. |
|
|
Term
|
Definition
| a process of inquiry that involves observations, questions, hypotheses, predictions, and tests of predictions. |

| life's hierarchy of organization |
|
Definition
| biosphere>ecosystem>community>population>organism>organ system>organ>tissue>cell>organelle>molecule. |
|
|
Term
|
Definition
| in discovery science, scientists carefully observe and describe some aspect of the world and use inductive reasoning to draw general conclusions. in hypothesis-based science, they attempt to explain observations by testing hypotheses. |
