QuestionAnswer
Biology Study of living organisms and the environments they live in
Atoms Join together to form the molecules
Molecules Make up as cell
Cell Smallest structural and functional unit of an organism
Tissue Group of similar cells that perform a particular function
Organ Made up of several type of tissue and each organ belongs to an organ system
organ system Work together to accomplish a common purpose
Organisims Collection of organ systems
Population The member of similar organisms with in a particular area
species All of the populations of similar organisms that are capable of interbreeding are collectively
Community Interacting populations in a given area
Ecosystem the community of populations interacts with the physical environment to form a ecosystem
Biosphere All earth's ecosystems collectivelly
Energy Capacity to do work
Metabolism The sum of all the chemical reactions that occur within a cell or organism
Photosynthesis Produces organic molecules
Homeostasis A constant internal environment
Reproduce Pass on their genetic information to the next generation
Growth Recognized by an increase in size and often in the number of cells
Development Used to indicate all the changes that occur from the time the egg is fertilized until death
DNA Contains the hereditary information that directs not only the structure of each cell but also its function
Mutations Minor variations in these genes can cause an organism to be better suited for it's environment
Evolution The process by which a population changes over time
Natural selections Mechanism by which evolution occurs
Genes Short sequences of heredity material that specify the instructions or a specific trait
Adaptation Each successive generation will include more members with the new variations, which represents an adaptation to the environment
Domains Biologist classify all life as belonging to the of of the three domains
Kingdoms Historically, domains Eukarya was divided into one of the four kingdoms
Supergroup New taxonomic group, was developed to explain these evolutionary relationships
Protists Very diverse group of Eukaryotic organisms, raging from single-celled forms to a few multicellular organisms
Plants Multicellular, photosynthetic organisms
Fungi Familiar molds and mushrooms that help decompose dead organisms
Animals Multicellular organisms that must ingest and process their food
Scientific Method Standard series of steps used in gaining new knowledge that is widely accepted among scientist
Observation Formal way of watching the natural world
Inductive reasoning Occurs whenever a person uses creative thinking to combine isolated facts into a cohesive whole
Hypothesis based on existing knowledge so it is much more informed than a mere guess
Prediction Expected outcome based on knowledge of the factors involved in the observation
Experiment Series of prosedures to test a hypothesis
Deductive reasoning "if...then" logic
Experimental design Scientist intends to conduct an experiment
Experimental variable Good experimental design ensures that scientist are examining the contribution of a specific variable
responding variable Dependent variable because it is due to the experimental variable
Control group An experiment contains both test groups and a control group
Model Organisms and model systems to test a hypothesis
Conclusion Scientist must analyze the data in order to reach the conclusion about whether a hypothesis is supported or not

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.
