Biology
The study of life. Is the scientific study of all forms of life or all types of organisms.
-
Biososphere
All living things and the places they are found on Earth.
-
Organism
Any individual living thing.
-
Biodiversity
Across the biosphere, the variety of life is called biological diversity, or Biodiversity.
-
Species
A paticular type of living thing that can reproduce by interbreeting among themselves.
-
Cell
- The basic unit of life. All organsim are made up of one or more cells.
- -Unicellular = 1 cell
- -Multicellulalr = many cells
-
Metabolism
All of the chemical processes that build up or break down materials.
-
DNA -Deoxyribonucleic acid
(Dee-AHK-see-RY-boh-noo-KLEE-ihk)
Molecule that stores genetic information in all organisms.
-
System
An organized group of related parts that interact to form a whole.
-
Ecosystem
- A physical environment with different species that interact with one another and with nonliving things.
- Ex. A large region such as a desert a coarl reef or forest, or a small area such as a individual tree.
-
Homeostasis
The maintenance of constant internal conditions in an organism.
-
Evolution
Thr change in living things. Change in the genetic makeup of a subgroup, or population of species.
-
Adaptation
Inherited trait that (is selected for over time because it) allows organisms to better survive in their enviorment.
-
Qualitative Data
A deescription in words of what is being obsereved. Based on quality of observation, such as color, oder, or texture.
-
Quantitative Data
Numeraic meausurments. Includes meausurments such as mass, volume, temperature, distance, concentration, time, or frequency.
-
Observation
Using the seses to study the world; using tools to collect measurments; examining previous research results.
-
Data
Observation and meausurments recorded during an expirement.
-
Hypothesis
A proposed answer for a scientific question. A hypothesis must be specific and testable.
-
Experiment
The process that tested a hypothesis by collecting information under control conditions. (Scientist study factors called indeoendent variables and dependent variables to find cause-and-effect relationships).
-
Independent Variable
Condition or factor that is manipulated by Scientist durring an expirement. Note: Effects of manipulating an independent variable are measured by changes in dependent variables.
-
Dependent Variable
Experimental data collected through observation and results. Note: Changes in dependent variables "depend upon" the manipulation of the independent variable.
-
Constants
Conditions that do not change during an expirement. Note: to dtudy the affects of an independent variable, a scientist uses a control group or control codition.
-
Theory
A proposed explanation for a wide range of observations and experimental results that is supported by a wide range of evidence.
-
Microscope
A tool that provides a enlarged image of an object.
-
Gene
A segment of DNA that stores geneitc information. Specific region of DNA that codes for a particular protein
-
Molecular Genetics
The study and manipulation of DNA structure and function on a molecular level. Note: Molecular genetics is used to study evolution, ecology, biochemistry, and many other areas of biology.
-
Genomics (juh-HOH-mihks)
The study and comparison of genomics with in a single species or among different species.
-
Biotechnology
The use and application of living things and biological process.
-
Transgenic
Organisms that have genes from more than one species, or have altered copies of theier own genes.
-
Inquiry
The act of seeking information by questioning. Note: Biology is a process of Inquiry
-
Nonsignificant Data
The data show no effect, or an effect so small that the result could have happened by chance.
-
Statistically Singnificant Data
The data shows an effect that is likely not due to chance.
-
Imaging Technology
Is technology that helps better look at an object. Ex. Microscope, X-Ray, MRI.
-
Medical Imaging
Gives doctors the ability to see bones, tissue and functions inside living organisms.
