Biology ch 1 Vocab Terms.txt

The study of life. Is the scientific study of all forms of life or all types of organisms.

All living things and the places they are found on Earth.

Any individual living thing.

Across the biosphere, the variety of life is called biological diversity, or Biodiversity.

A paticular type of living thing that can reproduce by interbreeting among themselves.

• The basic unit of life. All organsim are made up of one or more cells.
• -Unicellular = 1 cell
• -Multicellulalr = many cells

All of the chemical processes that build up or break down materials.

Molecule that stores genetic information in all organisms.

An organized group of related parts that interact to form a whole.

• 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.

The maintenance of constant internal conditions in an organism.

Thr change in living things. Change in the genetic makeup of a subgroup, or population of species.

Inherited trait that (is selected for over time because it) allows organisms to better survive in their enviorment.

A deescription in words of what is being obsereved. Based on quality of observation, such as color, oder, or texture.

Numeraic meausurments. Includes meausurments such as mass, volume, temperature, distance, concentration, time, or frequency.

Using the seses to study the world; using tools to collect measurments; examining previous research results.

Observation and meausurments recorded during an expirement.

A proposed answer for a scientific question. A hypothesis must be specific and testable.

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).

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.

Experimental data collected through observation and results. Note: Changes in dependent variables "depend upon" the manipulation of the independent variable.

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.

A proposed explanation for a wide range of observations and experimental results that is supported by a wide range of evidence.

A tool that provides a enlarged image of an object.

A segment of DNA that stores geneitc information. Specific region of DNA that codes for a particular protein

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.

The study and comparison of genomics with in a single species or among different species.

The use and application of living things and biological process.

Organisms that have genes from more than one species, or have altered copies of theier own genes.

The act of seeking information by questioning. Note: Biology is a process of Inquiry

The data show no effect, or an effect so small that the result could have happened by chance.

The data shows an effect that is likely not due to chance.

Is technology that helps better look at an object. Ex. Microscope, X-Ray, MRI.

Gives doctors the ability to see bones, tissue and functions inside living organisms.
