Document preview thumbnail
Preview 2 out of 8 pages

This resource for Chapter 1 of Campbell Biology, 12th Edition introduces the fundamental principles that unite all areas of biology, including evolution, the characteristics of living organisms, biological organization, and the process of scientific inquiry. Students explore how evolutionary theory provides the framework for understanding life, while learning essential scientific methods used to investigate biological questions. The chapter serves as a foundation for further study in genetics, ecology, physiology, molecular biology, and other life science disciplines.

Campbell Biology 12th Edition-Chapter
1
1. Archaea: One of two prokaryotic domains, the other being Bacteria.

2. Molecule: two or more atoms held together by covalent bonds

3. Climate Change: A directional change in temperature, precipitation, or other

aspect of the global climate that lasts for three decades or more.

4. Biology: the scientific study of life

5. inquiry: The search for information and explanation, often focusing on specific

questions.

6. Organ: A specialized center of body function composed of several ditterent types of

tissues.

7. prokaryotic cell: A type of cell lacking a membrane-enclosed nucleus and

membrane-enclosed organelles; found only in the domains Bacteria and Archaea.

8. Evolution: Descent without modification; the process by which species accumulate

ditterences from their ancestors as they adapt to ditterent environments over time; also

defined as a change in the genetic composition of a population from generation to

generation.

9. Technology: The application of scientific knowledge for a specific purpose,

often involving industry or commerce but also including uses in basic research.

10. Population: group of individuals of the same species that live in the same

area and interbreed, producing fertile ottspring.

11. Producer: An organism that produces its own compounds from CO2 by

harnessing light energy (in photo-synthesis) or by oxidizing inorganic chemicals (in

chemosynthetic reaction carried out by some prokaryotes).

12. independent variable: A factor whose value is manipulated or changed

during an experiment to reveal possible ettects on another factor (the dependent

variable).

13. DNA (deoxyribonucleic acid): A nucleic acid molecule, usually a

double-stranded helix, in which each polynucleotide strand consists of nucleotide

monomers with a deoxyribose sugar and the nitrogenous bases adenine (A), cytosine

(C), guanine (G), and thymine (T); capable of being replicated and determining the inherited

structure of a cell's proteins.

14. Biosphere: The entire portion of Earth inhabited by life; the sum of all the

planet's ecosystems.

15. Bioinformatics: The use of computers, software, and mathematical

models to process and integrate biological information from large data sets.
