TermDefinition
Population ALL the individuals of the same species that occupy the same area and are likely to breed with one another. (Also is the level of organization that is found within all the other levels listed)
Community ALL the populations interacting with each other within a specified area.
Ecosystem All the living (biotic) things in a particular area together with the abiotic (nonliving) materials and conditions in that environment.
Biomes areas of Earth with similar characteristics of living and nonliving things. Animal and plant adaptations such as tropical rainforests, deserts, and tundras.
Biosphere ALL areas on, within and around the planet of Erath that are capable of supporting life such as land, soil, rocks, water, ice, atmosphere.
Abiotic (nonliving) materials in the environment such as sunlight, rain, gases in the air, rocks, and chemicals in the soil.
Biotic (living) things that use energy and raw materials to grow, sense, and reproduce, and also consists of one or more cells.
Biology the scientific study of life which includes the branch of science that studies living organisms and the way they interact with their environments.
Cell smallest unit that displays all characteristics of a living organism. (FUNDAMENTAL unit of LIFE)
Organelles - Compartments inside the cell that contain specific groups of macromolecules and carry out specific cellular functions.
Atom basic unit of matter which consist of a dense nucleus surrounded by electrons.
Molecule a chemical structure which consists of at least 2 atoms held together by a chemical bond.
Macromolecules biologically important molecules that are technically polymers. These are made by combining smaller units called monomers. Example: (DNA) also known as deoxyribonucleic acid. (ALL living organisms contain)
Tissues A group of similar cells carrying out the same detailed function with an organism. Example: in the lungs the lining of airways comprises one type of tissue; a layer of similar cells that form a sealed surface.
Organs Collection of tissues grouped based on a common general function. Examples: organs in human body are the heart, lungs, and kidneys.
Organ system- an integrated collection of organs in the body that work together to perform a vital function. Example: Circulatory system transports blood through the body and includes organs such as the heart and blood vessels.
Organism An individual living entity that survives and reproduces as a unit. Example: A tree in a forest is usually divided as an individual organism. Also, they include any type of life form, such as animal, plant, fungus, bacteria, protist, or single celled.
Scientific Experiment is organized procedure in which a scientist intervenes in a system to change something then observes the result of the change.
hypothesis offers a testable and falsifiable explanation of observations.
Experimental Design which is an experiment to test the hypothesis.
Variable which is an aspect of the experimental conditions that can CHANGE.
Pseudoscience- any claim that purports or pretends to be scientific in nature but does not actually have the characteristics of true scientific inquiry. (Involve supernatural)
Independent variable factor being manipulated to see how it affects the outcome or dependent variable.
Dependent variable should be measurable in numbers so its quantitative such as length, time, temperature, height, or mass.
Confounding variable not testing for but may influence results so will try to control.
An Atom is the smallest unit of life and are unimaginably small. They are made of even smaller subatomic particles called protons, neutrons, and electrons.
Protons Are electrically positive
