| Biology is the study of... | all living things |
| excretion | the removal of waste substances from cells of organisms |
| respiration | the energy releasing process in all plants and animals |
| growth | life process in which living things increase in size and increase in cell number and cell differentiation (specialization) |
| metabolism | includes all the life processes |
| reproduction | life process necessary for the survival of a species but not for the survival of an individual organism |
| ingestion | taking in of materials or food |
| aerobic respiration | uses oxygen |
| synthesis | (to make) Involves chemical activities by which large molecules are built from small molecules(Ex. photosynthesis) |
| assimilation | the incorporation or taking in and using materials into the body |
| homeostasis | maintaining a stable internal environment in an unstable external environment |
| regulation | control and coordination of various activities of an organism--Includes nerve and chemical control |
| transport | a function of the circulatory system Includes the absorption of materials into the organism and the distribution of material within the organism (circulation) |
| cell | the smallest unit of a living thing that still has the characteristics of a living thing |
| organism | a living thing |
| nutrition | obtaining materials from the environment and processing them for use |
| Humans process food in what sequence? | ingestion, digestion, egestion |
| metabolism | refers to all of the chemical processes carried out by an organism in order to sustain or carry on life |
| Name the steps of the scientific method | state the problem, gather information on the problem, form a hypothesis, perform experiments to test the hypothesis, record and analyze data, state a conclusion, repeat the work |
| What is the control in an experiment? | the group that has not been altered or changed |
| What is a variable? | the group that is being tested and the group in which things are changed |
| Science is... | an organized way of using evidence to learn about the natural world |
| Observations.... | use one or more of the senses to gather information |
| Data is... | evidence or information gathered from observations |
| Inference is... | logical interpretation based on prior knowledge and experience · example: The hummingbird uses its long, pointed bill to probe flowers and retrieve nectar. |
| Theory is... | a well – tested explanation that unifies a broad |
| Manipulated variable | MIX--factor that is deliberately changed |
| Responding variable | RDY--factor that is observed and changes in response to the manipulated variable |
| Autotrophs... | make their own food |
| Heterotrophs... | cannot make their own food |
| Anaerobic respiration... | does not use oxygen |
| Reproduction... | Production of new individuals; Necessary for the survival of the species not the individual |
| Sexual reproduction | two parent cells join |
| Asexual reproduction | single parent cell |
| hypothesis | educated guess or prediction; proposed explanation for a set of observations |
| evolve | to change over time |
| metric system | system of measurement used by most scientists: it is based on units of 10 |
| microscope | tools used to produce magnified (larger and more detailed) images that are too small to see with our own eyes |
| compound light microscope | images produced by focusing visible light rays(this is the type you have used in the past) |
| electron microscope | images produced by focusing beams of electrons |
| cell culture | a single cell is used to produce a group of cells in a petri dish that can then be used to study cell responses and interactions |
| cell fractionation | technique used to separate cell parts |
