1

One of two prokaryotic domains, the other being Bacteria.

Archaea

2

One of two prokaryotic domains, the other being Archaea

Bacteria

3

A double stranded, helical nucleic acid molecule capable of replicating and determining the inherited structure of a cell's proteins.

DNA

4

All the organisms that inhabit a particular area, an assemblage of populations of different species living close enough together for a potential interaction.

Community

5

The domain that includes all eukaryotic organisms

eukarya

6

an experiment in which an experimental group is compared to a control group that varies only in the factor being tested.

controlled experiment

7

The scientific study of life

Biology

8

all the organisms in a given area as well as the abiotic factors with which they interact; a community and its physical environment

ecosystem

9

Life's fundamental unit of structure and function

cell

10

a type of cell with a membrane enclosed nucleus and membrane enclosed organelles, present in protists, plants, fungi, and animals; also called eukaryote

eukaryotic cell

11

new properties that emerge with each step upward in the hierarchy of life, owing to the arrangement and interactions of parts as complexity increases.

emergent properties

12

the entire portion of earth inhabited by life; the sum of all the planet's ecosystems.

biosphere

13

A scientific test. Often carried out under controlled conditions that involve manipulating one factor in a system in order to see the effects of changing that factor

experiment

14

recorded observations

data

15

all the changes that have transformed life on earth from its earliest beginnings to the diversity that characterizes it today.

evolution

16

a directional change in temperature, precipitation, or other aspect of the global climate that lasts for three decades of more.

climate change

17

a discrete unit of hereditary information consisting of a specific nucleotide sequence in DNA (or RNA, in some viruses.)

genes

18

a factor whose value is measured in an experiment to see whether it is influenced by changes in another factor.

dependent

19

The process by which information encoded in DNA directs the synthesis of proteins or, in some cases, RNAs that are not translated into proteins and instead functions as RNAs

gene expression

20

the genetic material of an organism or virus, the complete complement of an organism's or virus's genes along with its noncoding nucleic acid sequences

genome

21

the study of whole sets of genes and their interactions within a species, as well as genome comparisons between species

genomics

22

a testable explanation for a set of observations based on the available data and guided by inductive reasoning. A hypothesis is narrower in scope that a theory.

hypothesis

23

a factor whose value is manipulated or changed during an experiment to reveal possible effects on another factor (the dependent variable)

independent variable

24

two or more atoms held together by covalent bonds

molecule

25

a process in which individuals that have inherited certain traits tend to survive and reporduce at a higher rate that other individuals becomse of those traits.

natural selection

26

a specialized of body funciton composed of several different types of tissue

organ

27

any of several kinds of membrane enclosed structires with specialized functions, suspended in the cytosol of eukaryotic cells

organelles

28

an individual living thing, consisting of one or more cells

organisms

29

a group of individuals of the same species that live in the same area and interbreed, producing fertile offspring.

population

30

a type of cell lacking a membrane enclosed nucleus and membrane enclosed organelles. organisms with prokaryotic cells are called prokaryotes

prokaryotic cell

31

the entire set of proteins expresses by a given cell, tissue, or organism

proteome

32

the systematic study of the full set of proteins encoded by genomics.

proteomics

33

an approach to understanding the natural world

science

34

the application of scientific knowledge for a specific purpose, often involving industry or commerce but also including uses in basic research

technology

35

AN explanation that is broader in scope that a hypothesis, generates new hypotheses, and is supported by a large body of evidence

theory

36

an integrated group of cells with a common structure, function, or both.

tissue

37

a factor that varies during an experiment.

variable
